    Abstract

    The common green bottle fly, Lucilia sericata (Meigen) (Diptera: Calliphoridae), is a promising and useful managed pollinator for greenhouse agricultural crops. The fly can pollinate at lower and higher temperatures than European honeybee. However, management of the longevity of pollinators is important for growers using greenhouses. Previous studies using other insects showed that caffeine affects insect longevity and behaviors. For instance, European honeybee live longer and have increased memory after caffeine consumption. How caffeine affects the longevity and behavior of pollinators is worth investigating because it can affect pollinator’s behavior, extend longevity, or be an insecticide against pollinators. In the present study, therefore, the longevity and locomotion of L. sericata were investigated when they were given different caffeine concentrations. First, the longevity of L. sericata with five different caffeine concentrations was compared to the control. The results showed that higher concentrations of caffeine (2%, 1%, and 0.5%) significantly decreased the life span compared to lower concentrations (0.05% and 0.01%). Second, the locomotion activities of L. sericata were examined at those two caffeine concentrations with treated and control male and female flies utilizing a Drosophila Activity Monitor (DAM). Treatment with 0.05% caffeine dramatically reduced locomotion, but treatment of 0.01% caffeine did not. We also compared lipid concentrations of flies: flies treated with 0.05% caffeine had a lower lipid concentration compared to flies treated with 0% and 0.01% caffeine. These results indicate that caffeine had negative effects on the longevity and locomotion activities of the pollinator L. sericata in laboratory conditions.

  • Behavior, behavioral syndromes, and metabolism: the effects of artificial selection for death-feigning on metabolic rate Reviewed

    Abstract

    Death-feigning, or thanatosis, is an anti-predator behavioral strategy in many animals. Because individuals remain immobile while feigning death, individuals with longer durations of death feigning often show lower locomotor activity. Thus, metabolic rate, which is closely related to locomotor activity, may also be related to the intensity of death feigning. If there is a genetic correlation between death feigning and metabolism, metabolic rate may respond to selection on death-feigning behavior. Here, we tested for a relationship between metabolic rate and death-feigning using replicated populations of the red flour beetle (Tribolium castaneum) subjected to artificial bidirectional selection on the duration of death-feigning behavior. The results indicated that metabolic rate did not differ between populations selected for increased or decreased death feigning, although locomotor activity was significantly different between these treatments; populations selected for reduced death-feigning durations tended to be more active. These results suggest that death-feigning behavior is not genetically correlated with metabolic rate in T. castaneum.

    Authorship：Last author,　Corresponding author   Language：English   Publishing type：Research paper (scientific journal)   Publisher：Springer Science and Business Media LLC  

    Abstract

    Death feigning is thought to have evolved primarily as a predator avoidance behavior, and has been reported in 10 of the 31 orders of insects. However, there have been no reports of death-feigning behavior in Mecoptera species. We found that larvae of two scorpionfly species, Panorpa japonica and P. pryeri, showed death feigning in response to external stimuli by brush poking stimulation. First, we examined the frequencies of death-feigning postures. The two species showed two different postures of death feigning, “straight” and “ball.” Most of the 1st instar larvae of P. japonica and P. pryeri adopted the straight death-feigning posture. Next, we examined duration of death feigning. As the larval instar progressed, the death-feigning posture shifted from straight to ball in both Panorpa species. In P. japonica, the longest durations of death feigning were found in the 2nd to 3rd instars, while the longest duration of death feigning was found in the late 4th instar in P. pryeri larvae.

  • Reduced fitness in losers of leg-biting male combat compared to uncontested males in Zophobas atratus Reviewed

    Abstract

    Sexual dimorphism and male combat are observed in many species. Often, the outcome of male combat affects the outcome of subsequent combats, mating success, number of sperm, and fitness of the male’s offspring. Also, the quantity and quality of sperm may be regulated by winning or losing, depending on species ecology and mating system. However, very few studies have experimentally examined the influence of fight outcomes on male offspring fitness. We studied male combat in the giant mealworm (Zophobas atratus) in which males bite each other’s hind legs. We hypothesized that subsequent fitness could differ between winners and losers in the escalated male combat of this species. We measured several fitness traits including the number of eggs laid by mated females, and the number of hatches sired by uncontested males, winners, and losers in escalated and non-escalated combat, and compared the fitness of each winner and loser to that of an uncontested male. We also measured mating duration. The numbers of eggs and the percentages of hatched eggs of losers in the escalated combat were significantly reduced compared to that of the uncontested males. This reduction may be due to injuries from escalated leg- biting fights and a result of the sperm amount of the uncontested males being greater than that of the loser males.

    Abstract

    Death feigning, a state of immobility observed in many animals in response to external stimuli, is an anti-predator behaviour. Although previous studies showed that death-feigning behaviours are quantitative genetic traits, the knowledge of the heritable basis of death-feigning behaviour is lacking. To investigate the heritable basis of death-feigning behaviour, we used 3 laboratory strains of a braconid parasitoid wasp, Heterospilus prosopidis. The heritable basis using half-sib analysis, and the effects of different geographical backgrounds, rearing conditions in the laboratory, and host age were evaluated. The results of the half-sib analysis showed that the frequency of death feigning varied among sires, suggesting a certain extent of additive genetic variance. Also, the frequency of death feigning varied between geographical backgrounds and among strains. Death-feigning frequency was not affected by the age of the host. Our findings highlight the importance of genetic factors underlying the basis of the death-feigning behaviour and provide support for the genetic alterations of traits from the perspective of evolution in various animal species.

    Abstract

    Death feigning is hypothesized to be an anti-predator behavior in which prey is temporarily immobilized in response to external stimuli. While death feigning may be an effective predator-defense strategy, there may be trade-offs in terms of energy and time for finding food and/or mating. The duration of death feigning is regulated by the balance of various selection pressures, and its duration is influenced by many internal and environmental factors. However, little is known about the factors that influence arousal from death-feigning behavior. Sex pheromones are important semiochemicals that affect reproductive success and may influence the duration of death-feigning behavior. In this study, we aimed to investigate the effects of sex pheromones on the death-feigning behavior of the sweet potato weevil (Cylas formicarius) by conducting laboratory experiments. The results showed that males had a significantly shorter death-feigning duration in the presence of sex pheromones because it aroused them from their death-feigning behavior, but females were unaffected. This is the first study to show that sex pheromones alter death-feigning behavior. The results of this study elucidate the factors influencing predator-avoidance behavior and reveal the impact of death-feigning behavior on prey reproduction under predation pressure.

    Abstract

    The West Indian sweetpotato weevil, Euscepes postfasciatus, a serious pest of sweet potatoes, is being eradicated by sterile insect technique (SIT) in the south-western islands of Japan. Information on the diurnal movement of the target pests on host plants and where mating and egg-laying behavior occurs on the host is important for the application of SIT, which eradicates the target pest through mating of released sterile males and wild females. However, little such information is available on this species. In this study, male and female adults were released on host plants to examine the diurnal distribution on seedlings according to sex, as well as the sites where mounting behavior and egg laying occurs. The results showed that females left the host plant more frequently at night, whereas males were more likely to remain on the host plant at night. Both males and females stayed on the nodes of the host plant during the daytime. Mounting behavior also tended to occur more often at nodes. Furthermore, compared to unmated females, mated females stayed at the vertical top of the seedlings. However, it was found that eggs were often laid close to the roots rather than at the top of the vertical stems, even when the seedlings were placed upside down. The results of previous studies and this study will be discussed from the perspective of the application of SIT against E. postfasciatus.

    Abstract

    Movement is an important behavior observed in a wide range of taxa. Previous studies have examined genes controlling movement using wing polymorphic insects and genes controlling wing size. However, few studies have investigated genes controlling movement activity rather than morphological traits. In the present study, we conducted RNA sequencing using populations with higher (WL) and lower (WS) mobility established by artificial selection in the red flour beetle Tribolium castaneum and compared gene expression levels between selected populations with two replicate lines. As a result, we found significant differences between the selected populations in 677 genes expressed in one replicate line and 1198 genes expressed in another replicate line, of which 311 genes were common to the two replicate lines. Furthermore, quantitative PCR focusing on 6 of these genes revealed that neuropeptide F receptor gene (NpF) was significantly more highly expressed in the WL population than in the WS population, which was common to the two replicate lines. We discuss differences in genes controlling movement between walking activity and wing polymorphism.

    Abstract

    Several previous studies have reported geographic variation and/or latitudinal clines of morphological sexual characteristics, but there are few studies that consider reproductive traits that are not morphological. Here, we measured the proportion of females fertilized by males, frequency of reproductive failure in males, and number of female copulations of the red flour beetle Tribolium castaneum collected from fields in Japan to investigate the relationship between reproductive traits and latitude. Our results show substantial differences in the reproductive traits of both sexes among field populations. We identified latitudinal clines for reproductive traits in males, but not females. Moreover, female, but not male, reproductive traits were correlated with body size. Our study suggests that selection for male reproductive traits varies with latitude in T. castaneum.

    Significance statement

    It has been established that latitudinal gradients are frequently observed in the traits of numerous animal species, of which body size is a prime example. Analogously, latitudinal gradients have been documented in the reproductive traits of several animal species, indicating that sexual selection may be influenced by latitude, although the specific understanding thereof remains elusive. In this study, we quantified the male and female reproductive traits and analyzed their relationship with latitude in the red flour beetle Tribolium castaneum. Our findings indicate that male mating efficacy was superior at lower than at higher latitudes, but no discernible latitudinal gradient was observed in female mating frequency. These results imply that selective pressure on males of this species is stronger at lower than at higher latitudes.

    Abstract

    We examined the attraction of adults to six LEDs in the red flour beetles, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), which is widespread as a stored grain insect. In the experiment, bluish green and green were more attractive than the two UVs, blue, and red LEDs only in females. On the other hand, no difference was found in attraction among the six LEDs in males. Next, we investigated the relationship between light intensity and attractiveness. No sexual difference in attractiveness in different light intensities was found, but the strongest light intensity was more attractive than other light intensities. Finally, we investigated the relationship between light attraction and strains artificially selected for the duration of death feigning. Short-strain beetles were more attracted to UV lights than long-strain beetles.

    Death-feigning behaviour is a phenomenon in which a prey is rendered motionless due to stimulation or threat from a predator. This anti-predator defence mechanism has been observed across numerous animal taxa and is considered adaptive in nature. However, longer durations of death feigning can result in decreased opportunities for feeding and reproduction, and therefore is often associated with fitness costs as compared to environments without predators. Differences have also been observed in the frequencies and durations of death feigning within populations, and these differences are thought to be influenced by the balance between survival and other fitness costs. Furthermore, this balance is predicted to vary in response to changes in environmental conditions. In this study, we examined the death feigning in 38 populations of the red flour beetle ( Tribolium castaneum ). Our results demonstrate that frequencies and durations of the death feigning in T. castaneum show geographical variations and a latitude cline, indicating that this behaviour is influenced by location as well as latitude. This study is the first to demonstrate the existence of a latitudinal cline in death feigning and suggests that death-feigning behaviour might have evolved in response to environmental factors that vary with latitude.

    Since the variables inherent to various diseases cannot be controlled directly in humans, behavioral dysfunctions have been examined in model organisms, leading to better understanding their underlying mechanisms. However, because the spatial and temporal scales of animal locomotion vary widely among species, conventional statistical analyses cannot be used to discover knowledge from the locomotion data. We propose a procedure to automatically discover locomotion features shared among animal species by means of domain-adversarial deep neural networks. Our neural network is equipped with a function which explains the meaning of segments of locomotion where the cross-species features are hidden by incorporating an attention mechanism into the neural network, regarded as a black box. It enables us to formulate a human-interpretable rule about the cross-species locomotion feature and validate it using statistical tests. We demonstrate the versatility of this procedure by identifying locomotion features shared across different species with dopamine deficiency, namely humans, mice, and worms, despite their evolutionary differences.

    Tonic immobility and escape are adaptive anti-predator tactics used by many animals. Escape requires movement, whereas tonic immobility does not. If anti-predator tactics relate to weapon size, males with larger weapons may adopt tonic immobility, whereas males with smaller weapons may adopt escape. However, no study has investigated the relationship between weapon size and anti-predator tactics. In this study, we investigated the relationship between male weapon size and tonic immobility in the beetle
    <italic>Gnathocerus cornutus</italic>
    . The results showed that tonic immobility was more frequent in males with larger weapons. Although most studies of tonic immobility in beetles have focused on the duration, rather than the frequency, tonic immobility duration was not affected by weapon size in

    <title>Abstract</title>
    Animal behaviours often dependent on age. In many insect species, walking shows an age-dependent decline, and food intake may also be dependent on age. However, few studies have investigated the relationship between age and walking or food intake. In the present study, we compared walking traits and food intake among individuals of different ages in the assassin bug <italic>Amphibolus venator</italic> (Hemiptera, Reduviidae). The present results showed an age-dependent decline in walking, similar to findings in many animal species. On the other hand, food intake showed a positive correlation with age. Therefore, the decline in walking did not lead to a decline in feeding. The positive relationship between food intake and age may be related to the type of predation, sit-and-wait, used by <italic>A. venator</italic> via alterations in investment in reproductive traits with age.

    Many species show rhythmicity in activity, from the timing of flowering in plants to that of foraging behavior in animals. The free-running periods and amplitude (sometimes called strength or power) of circadian rhythms are often used as indicators of biological clocks. Many reports have shown that these traits are highly geographically variable, and interestingly, they often show latitudinal or longitudinal clines. In many cases, the higher the latitude is, the longer the free-running circadian period (i.e., period of rhythm) in insects and plants. However, reports of positive correlations between latitude or longitude and circadian rhythm traits, including free-running periods, the power of the rhythm and locomotor activity, are limited to certain taxonomic groups. Therefore, we collected a cosmopolitan stored-product pest species, the red flour beetle <italic>Tribolium castaneum</italic>, in various parts of Japan and examined its rhythm traits, including the power and period of the rhythm, which were calculated from locomotor activity. The analysis revealed that the power was significantly lower for beetles collected in northern areas than southern areas in Japan. However, it is worth noting that the period of circadian rhythm did not show any clines; specifically, it did not vary among the sampling sites, despite the very large sample size (n = 1585). We discuss why these cline trends were observed in <italic>T</italic>. <italic>castaneum</italic>.

    <title>Abstract</title>
    Circadian rhythms, their free-running periods and the power of the rhythms are often used as indicators of biological clocks, and there is evidence that the free-running periods of circadian rhythms are not affected by environmental factors, such as temperature. However, there are few studies of environmental effects on the power of the rhythms, and it is not clear whether temperature compensation is universal. Additionally, genetic variation and phenotypic plasticity in biological clocks are important for understanding the evolution of biological rhythms, but genetic and plastic effects are rarely investigated. Here, we used 18 isofemale lines (genotypes) of Gnatocerus cornutus to assess rhythms of locomotor activity, while also testing for temperature effects. We found that total activity and the power of the circadian rhythm were affected by interactions between sex and genotype or between sex, genotype and temperature. The males tended to be more active and showed greater increases in activity, but this effect varied across both genotypes and temperatures. The period of activity varied only by genotype and was thus independent of temperature. The complicated genotype–sex–environment interactions we recorded stress the importance of investigating circadian activity in more integrated ways.

    <title>Abstract</title>
    Tonic immobility is an adaptive anti-predator behaviour observed in many species. This anti-predator behaviour is often correlated with a species’ movement motivation, so a relationship between the duration of tonic immobility and morphological traits supporting movement would be expected. Using the red flour beetle, <italic>Tribolium castaneum</italic>, we carried out two-way artificial selection for the duration of tonic immobility over more than 43 generations, establishing populations with longer (L) and shorter (S) tonic immobility durations compared to those of a non-selected control (C) population. Here, we investigated differences in walking motivation and leg length between the selected populations. Walking motivation was significantly higher in beetles from the S population than that in those from the L population. Moreover, S-population beetles of both sexes had significantly longer legs than those from L and C populations. The present results suggest the evolution of longer legs in response to selection pressure for a shorter duration of tonic immobility in <italic>T. castaneum</italic>.

    <title>Abstract</title>
    The molecular basis of death feigning, an antipredator behavior that has received much attention recently, was analyzed. We compared the gene expression profiles of strains with different behaviors, i.e., different durations of death feigning, in the beetle <italic>Tribolium castaneum</italic>. Beetles artificially selected for short (S) and long (L) durations of death feigning for many generations were compared thoroughly by RNA sequencing. We identified 518 differentially expressed genes (DEGs) between the strains. The strains also showed divergence in unexpected gene expression regions. As expected from previous physiological studies, genes associated with the metabolic pathways of tyrosine, a precursor of dopamine, were differentially expressed between the S and L strains; these enzyme-encoding genes were expressed at higher levels in the L strain than in the S strain. We also found that several genes associated with insulin signaling were expressed at higher levels in the S strain than in the L strain. Quantitative real-time PCR analysis showed that the relative expression levels of <italic>Tchpd</italic> (encoding 4-hydroxyphenylpyruvate dioxygenase, <italic>Hpd</italic>) and <italic>Tcnat</italic> (encoding N<italic>-acetyltransferase</italic>, <italic>Nat</italic>) were significantly higher in the L strain than in the S strain, suggesting the influence of these enzymes on the supply of dopamine and duration of death feigning.

    Costs of reproduction include costs of producing eggs and of mating itself. In the present study, we made an experimental investigation of costs of reproduction in the Mediterranean fruit fly (medfly, Ceratitis capitata). We demonstrated that virgins live longer than non–virgin females. However, in strong contrast to most findings within the Diptera, non–virginity had no detectable effect on egg production. Therefore the increased longevity of the virgin females cannot be attributed to an increase in egg production in non–virgin females, and instead indicates a cost of mating. A comparison of the life spans of normal females and those sterilized by low doses of X–irradiation, revealed an additional cost of egg production. There were no significant differences in remating levels between females that did and did not lay eggs, showing that the cost of producing eggs is independent of mating frequency. Medfly females therefore suffer a decrease in survival as a result of egg production and of mating, and these costs are independent of one another. To put our results into context, we reviewed the existing literature on the effects of mating on longevity, egg production and sexual receptivity for 64 species of Diptera, and examined the pattern of mating effects that emerged.

    The characteristics of oviposition punctures caused by sterile females of the melon fly, Bactrocera cucurbitae, and an evaluation of its economic damage were investigated in Okinawa, Japan. It was confirmed in a field-cage experiment that sterile females make oviposition punctures (sterile stings) on cucurbit fruits. The features of sterile stings were different depending on the species of fruits and were classified into five types. The punctures on cucurbit fruits collected in fields were checked and identified as sterile stings or not, using the criterion obtained from the field-cage experiment. The rates of damaged fruits by sterile females were estimated to be lower than 1% in cucumber, sponge gourd and bitter gourd.

    The overwintering aggregations of the leaf-footed plant bug, Leptoglossus australis, were observed on Okinawa Island during February through March, 1985. The aggrega-tions were formed on the withered leaves of the host plant, Luffa cylindrica, and the nonhost plants, Capsicum annuum, Lacluca longifolia, Curia papaya, and Rumex japonicus. Aggregated plant bugs gradually dispersed to fresh host plants from early March.

    当該年度は、確立したコクヌストモドキの不妊化技術を駆使して、以下の実験進化を実施した。不妊オス集団中に、不妊雄など雌にとってのハズレ雄が含まれる時、もし雌がそれを識別できるなら、雌はハズレ雄との交尾もしくはハズレ雄の精子を用いた受精を回避すると推測できる。一方で、雌がハズレ雄を識別できない場合には、多雄交尾を行う雌が繁殖失敗のリスクを低減し、適応度の減少を防ぐことができるため、雌の交尾頻度が上昇するかもしれない。本研究では、コクヌストモドキを用いて、放射線照射によって人工的に不妊化した雄を含ませた集団で当該年度は、新たに16世代に渡って累代飼育する実験進化の手法によって雌の進化的応答を調査した。その結果、処理系統の雌を１回目に正常の雄、２回目に不妊雄と交尾させたときの、雌の産んだ卵の孵化率と、対照系統の雌を１回目に正常の雄、２回目に不妊雄と交尾させたときの、雌の産んだ卵の孵化率との間に差は見られなかった。このことは、本種の雌は、不妊雄と同居させて世代を重ねた雌が不妊雄の精子を避けるように進化したことを示している。これは隠れた雌による実験的な進化を世界で初めて実証したのみにとどまらず、不妊化法においても野生雌が不妊雄の精子を選別する進化を引き起こす可能性を示唆しているため、不妊化法の応用においても重要な可能性を示唆したものである。また実験室で得られた進化実験の結果が、野外で実際に不妊化法が実施されてる現場でも同様の反応が見られるのかについて、今年度は喜界島の野生虫を入手する段取りを整えた。

    本研究では野外採集が容易で、世代を重ねた実験進化に適し、ゲノム操作系が確立したコクヌストモドキをモデルとし、ゲノムから群集まで包括的な理解を目指す。これまでの研究で天敵に出会うと死んだふりで回避し自然選択に有利なロング系統と、普段からよく動き異性との出会いと交尾が多く性選択に有利なショート系統を育種した。系統間ではチロシン代謝系遺伝子群によって制御されるドーパミンの発現が有意に異なり、さらにゲノム比較解析によりドーパミン関連遺伝子領域に系統間で高頻度の変異が見つかった。本研究では「動き」を支配するゲノムを操作した個体の適応度を測定し、自然選択と性選択に及ぼす集団レベルの影響を評価する。当該年度は、コクヌストモドキの死んだふりを長い方向に育種したロング系統とショート系統に関連する遺伝子のゲノム同士のコネクション解析を行い、本種の動きと不動行動の長さに関連する標的遺伝子を特定できた。特定できた遺伝子のmRNAをコクヌストモドキの成虫にインジェクションし、標的遺伝子をノックダウンすることに成功した。長い死にまね時間を選抜したロング系統で標的遺伝子(Hpd)をノックダウンした結果、死んだふり持続時間が有意に短くなることが明らかとなった。また標的領域のゲノムを編集するために、これまで幼虫へのインジェクションを計画していたが、今回新たに成虫にインジェクションする技術開発の準備を整えた。野外の生態学的な調査において、全国からコクヌストモドキを採集して飼育し、各形質を測定したところ、北に生息する集団ほど、死んだふりの持続時間が長く、さらに概日リズムの変異を測定するための活動性の振幅度合いが小さくなることが、本研究によって世界ではじめて明らかにできた。

    The study of how behavioral traits controlled by organismal movement affect fitness was conducted using insects as material. Behaviors targeted were mainly predator-prey strategies, predation strategies, movement-dispersal strategies, and reproductive and mating strategies. The target organisms were mainly insects of the order Coleoptera. In particular, we conducted artificial selection experiments for walking and immobility among the movement traits of Tribolium beetles, and examined correlation responses among established breeding lines. The results revealed that a group of genes in the tyrosine metabolism system mediated by dopamine is involved in the movement of the organism.

    コクヌストモドキの「動き」が異なる選抜系統より、活動量の多い系統（H系統）と少ない系統（L系統）の成虫をそれぞれ任意に5個体抽出し、脳を摘出し、RNAseqによるトランスクリプトーム比較を行った。その結果、系統間で518の発現の異なる遺伝子を検出できた。選抜した系統間では、当初予期していなかった遺伝子領域にも発現差があったが、これまでの生理学的な研究の結果から発現の違いが予期されていたチロシン代謝系に関連する遺伝子（ドーパミンの前駆体物質）にも系統間で差が見られた。これら関連遺伝子のエンザイム遺伝子はH系統よりもL系統でより多くの発現が見られた。そこで、リアルタイムPCR解析を行ったところ、Tchpd (Hpd) とTcnat (Nat)がH系統に比べてL系統で、相対的な発現量が高かった。このことは活動量とドーパミン供給に関する酵素の影響を示唆している。そのうち、リアルタイムPCRで発現量の差が2倍以上であったHpd遺伝子についてRNAiを行った。L系統の成虫よりRNAを摘出し、逆転写によりｃDNAを合成し、LinearDNAを作成した。それによって合成したdsRNAをL系統の秀麗幼虫にインジェクションした。純水及びVermilionも同量インジェクションし、コントロールとした。リアルタイムPCRの結果、dsHPDのインジェクションによって、HPDの発現量が半分以下に抑制されていたが、成虫の活動量に変化は見られず、成虫の分散距離（ナビゲーション形質）を比較したがノックダウンによる効果は認められなかった。これと並行して、①確立した系統間で生活史形質の比較解析、②工学および計画班A02との連携研究において、昆虫類の移動と活動量の解析、③野外コクヌストモドキ集団の歩行軌跡の測定と地域集団の系統間推定、④計画班B01と連携して海鳥が海上で捕獲する昆虫種類の同定を行った。

    Locomotor activities and circadian rhythms of long-reared (more than 35 years) and wild populations of Tribolium castaneum (Coleoptera: Insect) were compared. We found significantly higher percentages of arrhythmic individuals in the long-reared population compared to the population caught in the wild. Only males were compared because no difference between the sexes was found in the percentage of arrhythmic beetles. Next, comparison of the circadian rhythms of wild and long-reared beetle populations showed no significant difference between the populations. The result suggests that the circadian rhythm in T. castaneum has been lost during long-rearing under an artificial condition. We will discuss arrythmicity in organisms.

    Walking behavior of a model beetle, the red flour beetle, Tribolium castaneum, has been artificially selected for over 20 genertaoions. The strains selected for longer (WL) and shorter walking (WS) ability have been established. WL strains had higher mating success than WS strains only in males but WS strains had lowewr attack rates from predator than WL strains. The investigation of sexual traits showed that WS strains males had higher sperm competition ability than WL males, indicating these have different strategies for pre-mating and post-mating in the two strains. Also, the two strains had different shape in their gential organs, suggesting reproductive isolation concering for dispersal ability by walking in insects.

    The relationship between lose-win of male combat and memory was examined in the broad horned beetle, Gnatocerus cornutus. Experience-dependent tactics of males trying to gain access to females were examined. Losing decreased a male's rate of fighting for four days, and few defeated males fought any males. The experience of losing not only decreased a male's aggressiveness but also switched the male behavior from fighting to dispersal from the fighting arena. The volume of ejaculation by loser males increased when they met a female and copulated with her. In Riptortus pedestris, male combat behavioral patterns changed during a day.

    Timing of reproduction including flowering, spawning, or mating of many organisms has restricted time-zone during a successive organism action, for example, particular seconds, hours, days, seasons or years. We cloned the clock gene period from two strains of melon fly, in one individuals mate early in the day, whilst in the other individuals mate later. The deduced amino acid sequences of PERIOD proteins for these two strains were reported to be identical. We cloned another clock gene cryptochrome (cry) from the two strains, and found two stable amino acid substitutions in the strains. The results suggest the influence on allochronic reproductive isolation of clock gene.

    今年度は,昆虫の活動性と関連のある生体アミン等物質のうち、ドーパミン以外のオクトパミン・チラミン・セロトニンなどの生体アミンの脳内存在量を調べた。その結果、長い時間死にまねするロング系統と短い時間死にまねするショート系統では、これらの存在量に有意な差はなかった。これまでの研究結果をまとめると、両系統ではドーパミンの脳内存在量に有意な差があること、ドーパミンのアクチベータであるカフェインの経口摂取および体内へのインジェクションが、ロング系統の死にまね時間を有意に短縮することから、コクヌストモドキの死にまね持続時間を左右している神経伝達物質がドーパミンであると結論づけた。またコクヌストモドキは、天敵であるアダンソンハエトリグモに襲わせたときには, ベンゾキノンを放出しないことが明らかとなり、死にまね行動の動かないという動作自体が有効であること。さらに、集団で暮らす本種では、不動という行為は、死にまねを行う個体の近隣に生息する同種他個体もしくは異種の個体が動き回ることで、天敵の興味をそちらに向ける効果のあることが判明した。このことは死にまねが、集団で暮らす個体にとっては利己的な行為として進化しうること、さらにこの効果が集団サイズをより大きくする可能性を示唆した。さらに死にまね行動と交尾行動には、遺伝的基礎を伴うトレードオフが存在することも証明した。

    イネの害虫であるニカメイガChilo suppressalisは、イネだけでなくイネ科雑草のマコモにも寄生することが知られている。そしてイネ個体群とマコモ個体群の間では、近縁な昆虫種間の生殖隔離機構の重要な要因の1つである交尾時刻が異なっている。すなわち、イネ系統は日没直後に交尾し、マコモ系統では日没約6時間後に交尾する。キイロショウジョウバエでは、交尾時刻の違いは測時機構の影響を受け、生殖隔離に時計遺伝子が関与する可能性が示唆されている。それゆえ交尾時刻の違う本種の個体群間では体内時計と測時機構に変化が生じている可能性がある。そこで本研究では、琵琶湖を有するため農薬散布が少なく本種の両ホストレースの同所的生息が確認された滋賀県で採集した両個体群を用いて、アクトグラフ装置による歩行活動の概日リズム計測を行なった。イネ個体群の概日リズムの自由継続周期(τ)は23.71±0.128時間、マコモ個体群の概日リズムのτは25.96±6.028時間で両ホストレース間に有意な差が見られた。この約2時間のずれはオスの活動時間帯のピークのずれと一致していることもわかった。
    これらの発見は、ニカメイガの両ホストレースが、概日リズムに支配される測時機構を介した同所的な時間的生殖隔離(アロクロニックな生殖隔離)の状態にあることを示す。
    そこで、概日リズムを制御する時計遺伝子period(約100bp)およびdoubletime(ほぼ全長:約1000bp)の塩基配列解析を行った。その結果、個体間およびホストレース問でいくつかのアミノ酸置換が発見された。今後、ホストレース間の交尾時刻の違いの原因遺伝子としての、概日リズム時計遺伝子の特定への道を築くことができ、将来の生殖隔離候補遺伝子の探索への可能性が開かれた。

    The number of males which a female mates with shows a large variation among animal species. This interspecific variation has been studied for a long time, based on hypotheses that invoke benefits of polyandry for females. We studied the evolution of monogamy/polyandry by using a species that has the genetic variation of the degree of polyandry among populations. This feature makes the crossing among populations with different levels of polyandry possible. We used the adzuki bean beetle (Callosobruchus chinensis). First, we examined the possibility that factors in one sex is responsible for the different levels of polyandry among populations. There were three possible case : only females are responsible, only males are responsible, and both are responsible. We also showed that there was a genetic variation of levels of polyandry among populations. Artificial selection experiments showed no correlated response in the rates of mating in two sexes. This suggested that the no genetic correlation in the rates of mating of two sexes. The direct benefit of polyandry for females was not shown. Several components of offspring fitness did not show the indirect benefit of polyandry for females. Males in the population with a higher level of polyandry showed a larger ability of sperm competition over males of the population with a lower level of polyandry. The level of polyandry was also affected by conditions including the time in a day and substrate for oviposition.

    A diamondback moth (DBM) strain resistant to fenvalerate was established and the effects of sublethal dose of the insect on egg size and fecundity were examined. The eggs of the selected strain were significantly smaller than those of non-selected strain. The fecundity of females of the selected strain tended to be higher than that of the non-selected strain. The survival rate of the selected strain was lower than that of the non-selected strain.
    To determine mode of inheritance of resistant development and of reduction of egg size in DBM, F_1 offspring of reciprocal crosses were compared with their parental lines for these traits. Several fitness components were also compared between F1 offspring of reciprocal crosses as well as the resistant and susceptible lines to detect maternal effects on the components including egg size. The dose-mortality regression lines of the F_1 hybrid of susceptible females and resistant males (SR) and resistant females and susceptible males (RS) were roughly intermediate between that of parental lines, i.e., SS and RR. This result indicates that the mode of inheritance of fenvalerate resistance was neither complete dominant nor recessive with no sex-linkage. The egg size of RR lines was significantly smaller than that of the SS lines. The RS and SR lines have an egg size close to that of their own matrilineage. It was considered that the mode of inheritance of resistance and that of egg size were different from each other, although the selection experiment showed that there is a negative correlated response between these parameters.
    The recovery of susceptibility to fenvarelate in resistant strains of DBM was examined through 10 generations after freeing then from insecticide selection under harsh-rearing (Harsh lines) and optimal-rearing conditions (Optimal lines). The LD_<50> values were lower for the Harsh lines than for Optimal lines in all the generations. Egg size of both lines increased gradually through 10
    Generations. Comparisons of these two lines show that the egg size increased more rapidly in Harsh lines than in Optimal lines in early generations.
    Comparison of immature survivability of Harsh and Optimal lines reared under those conditions showed that the survivability of Harsh line individuals was significantly lower than for those of Optimal lines. These results suggest that susceptibility might recovery more quickly in Harsh lines than in Optimal lines because resistant insects with small eggs had lower susceptibility than susceptible insects with normal eggs.

    The mechanism by which a clock gene pleiotropically controlling life history and behavioral traits causes reproductive isolation is explained using a model species, the melon fly, Bactrocera cucurbitae (Coquillett) (Diptera : Tephritidae). Melon flies mate once a day, at dusk. The population selected for life history traits exhibits correlated responses in the time of mating during the day. For example, the fly populations selected for faster (slower) development have an earlier (later) time of mating. A circathan rhythm controls the time of mating. The circadian periods in constant darkness were about 22h in lines selected for a short developmental period and about 31 h in lines selected for a long developmental period. The data on crosses between the selected lines indicated that the developmental period is controlled by a polygene, whereas the circadian period may be controlled by a single clock gene. These results suggest a clock gene pleiotropically controls developmental and circadian periods in the melon fly. Reproductive isolation may often evolve as an indirect (pleiotropic) consequence of adaptation to different environments or habitats. For example, niches that are temporally or seasonally offset can select organisms with different developmental characteristics. These development differences can inadvertently cause reproductive isolation by a variety of means including shifts in mating activity patterns. The difference in time of mating between populations selected for developmental period translated into significant prezygotic isolation, as measured by mate choice tests. If the mating time between populations differed more than 1 h, the isolation index was significantly higher than zero. These findings indicate that premating isolation can be established by a pleiotropic effect of a clock gene. There are many examples in which the difference in timing of reproduction prevents gene flow between populations, such as the egg spawning time in marine organisms, the flowering time in angiosperms, and the time of mating in insects. In, such, organisms ; if genetic correlations between circadian rhythm and reproductive traits exist, multifarious divergent selection for life history traits would often accelerate the evolution of reproductive isolation through clock genes. Natural populations may diverge in reproduction time through drift, direct natural selection for time of reproduction, or as a by-product effect of genetic correlations. In any case, clock genes are keys in reproductive isolation. We also analyzed sequence of amino-acid of period and doubletime genes, so called as clock genes, in short and long developmental period lines. The difference in a point amino-acid difference in doubletime was detected between short and long lines, and this difference might be related to the difference in mating time of Bactrocera cucurbitae. To examine this, we need to identify Drosophila melanogaster transjenic system, a null mutant of doubletime.
