• A potential evolutionary trap for the extended phenotype of a nematomorph parasite

  Yuna Sawada, Nozomu Sato, Takeshi Osawa, Kazuma Matsumoto, Ming-Chung Chiu, Ryuichi Okada, Midori Sakura, Takuya Sato

  Abstract Human activities introduce new environmental cues to wild organisms, leading to maladaptive behavioral and life history decisions known as the “evolutionary trap.” This trap is thought to be a major conservation concern for free-living organisms. However, it has never been studied in endosymbionts, one of the most successful and diverse life forms on Earth. Here, we examine this trap in the extended phenotype of a parasite that exploits the visual system of hosts to alter host behavior for its benefit. Arboreal mantids infected by nematomorph parasites are drawn to horizontally polarized light, thereby inducing them to enter the water. In this study, we found that the degree of linear polarization (DOP) of reflected light served as a reliable environmental cue for identifying perennial waters, where nematomorphs can survive in their aquatic life stage without drying out. Infected mantids exhibit attraction to horizontally polarized light with higher DOP in behavioral assays and jumped into pools reflecting light with higher DOP in field experiments. The asphalt road reflected horizontally polarized light closely resembling the polarization levels observed in perennial waters, likely leading to a higher prevalence of mantids on asphalt roads compared with those found in natural arboreal habitats. In a field experiment, we observed infected mantids walking on asphalt roads more often than on cement roads. These findings imply that evolutionary traps can endanger endosymbionts beyond their hosts that directly perceive environmental cues.

• Visual learning in tethered bees modifies flight orientation and is impaired by epinastine

  Norihiro Kobayashi, Yuji Hasegawa, Ryuichi Okada, Midori Sakura

  Abstract Visual-orientation learning of a tethered flying bee was investigated using a flight simulator and a novel protocol in which orientation preference toward trained visual targets was assessed in tests performed before and after appetitive conditioning. Either a blue or a green rectangle (conditioned stimulus, CS) was associated with 30% sucrose solution (unconditioned stimulus, US), whereas the other rectangle was not paired with US. Bees were tested in a closed-looped flight simulator 5 min after ten pairings of the US and CS. Conditioned bees were preferentially oriented to the CS after such training. This increase in preference for CS was maintained for 24 h, indicating the presence of long-term memory. Because the total orienting time was not altered by conditioning, conditioning did not enhance orientation activity itself but increased the relative time for orientation to CS. When 0.4 or 4 mM epinastine (an antagonist of octopamine receptors) was injected into the bee’s head 30 min prior to the experiment, both short- and long-term memory formation were significantly impaired, suggesting that octopamine, which is crucial for appetitive olfactory learning in insects, is also involved in visual orientation learning.

• Possible Role of Polarized Light Information in Spatial Recognition in the Cricket Gryllus bimaculatus.

  Nobuaki Matsubara, Ryuichi Okada, Midori Sakura

  Many insects are able to use skylight e-vector patterns to deduce their heading direction. Crickets have been well known to orient themselves to certain e-vector orientations to keep their walking direction. However, it is still unknown if crickets are able to utilize polarized light information for spatial recognition. Using an experimental paradigm similar to the Morris water maze for rodents, here we examine the possibility that the cricket Gryllus bimaculatus can utilize polarized light information to find the target place. Crickets were placed in a round arena with a heated floor, a portion of which was cooled, and a cross-shaped e-vector pattern was presented from the top of the arena so that the cricket could find the cool spot by walking along the e-vector direction. When the arrangement of the e-vector pattern and the cool spot were fixed throughout the experiments, the time and the walking distance to find the cool spot were significantly decreased with increasing trials, but not when the e-vector pattern was rotated between each trial. Moreover, a model selection indicated that the visual stimulus contributed to the decrease in time and distance. To investigate the cricket's exploration patterns in the arena, a test trial in which the whole floor was uniformly heated was performed before and after the training trials. In the test trial, the crickets trained with the positionally fixed e-vector pattern showed wall-following behavior for a significantly longer time than those untrained and those trained with random e-vector patterns.

• Enhanced polarotaxis can explain water-entry behaviour of mantids infected with nematomorph parasites

  Nasono Obayashi, Yasushi Iwatani, Midori Sakura, Satoshi Tamotsu, Ming-Chung Chiu, Takuya Sato

  A wide range of parasites manipulate the behaviours of their hosts in order to complete their life cycle1. Alteration of phototaxis is thought to be involved in host manipulation in many cases2,3. However, very little is known about what features of the light (intensity, spectrum, polarization) alter behaviour. Here we report that arboreal mantids (Hierodula patellifera) infected by nematomorph parasites (Chordodes sp.) are attracted to horizontally polarized light, which could induce the mantids to enter water, where the parasites can then emerge and reproduce. In a two-choice test, infected mantids were attracted to horizontally but not vertically polarized light. Uninfected mantids were not attracted to either. In a field experiment, 14 infected mantids entered a deep pool, where the water surface strongly reflected horizontally polarized light. By contrast, only two mantids entered a shallow pool, where the surface reflection had higher light intensity but weaker polarization. To our knowledge, this is the first study demonstrating that a manipulative parasite can take advantage of its hosts' ability to perceive polarized light stimuli to alter host behaviour.

• Orientation to polarized light in tethered flying honeybees

  Norihiro Kobayashi, Ryuichi Okada, Midori Sakura

  Many insects exploit the partial plane polarization of skylight for visual compass orientation and/or navigation. In the present study, using a tethering system, we investigated how flying bees respond to polarized light stimuli. The behavioral responses of honeybees (Apis mellifera) to a zenithal polarized light stimulus were observed using a tethered animal in a flight simulator. Flight direction of the bee was recorded by monitoring the horizontal movement of its abdomen, which was strongly anti-correlated with its torque. When the e-vector orientation of the polarized light was rotated clockwise or counterclockwise, the bee responded with periodic right-and-left abdominal movements; however, the bee did not show any clear periodic movement under the static e-vector or depolarized stimulus. The steering frequency of the bee was well coordinated with the e-vector rotation frequency of the stimulus, indicating that the flying bee oriented itself to a certain e-vector orientation, i.e. exhibited polarotaxis. The percentage of bees exhibiting clear polarotaxis was much smaller under the fast stimulus (3.6 deg s−1) compared with that under a slow stimulus (0.9 or 1.8 deg s−1). Bees did not demonstrate any polarotactic behavior after the dorsal rim area of the eyes, which mediates insect polarization vision in general, was bilaterally covered with black paint. Preferred e-vector orientations under the clockwise stimulus varied among individuals and distributed throughout −90 to 90 deg. Some bees showed similar preferred e-vector orientations for clockwise and counterclockwise stimuli whereas others did not. Our results strongly suggest that flying honeybees utilize the e-vector information from the skylight to deduce their heading orientation for navigation.

• Neuroethology of the Waggle Dance: How Followers Interact with the Waggle Dancer and Detect Spatial Information.

  Hiroyuki Ai, Ryuichi Okada, Midori Sakura, Thomas Wachtler, Hidetoshi Ikeno

  Since the honeybee possesses eusociality, advanced learning, memory ability, and information sharing through the use of various pheromones and sophisticated symbol communication (i.e., the "waggle dance"), this remarkable social animal has been one of the model symbolic animals for biological studies, animal ecology, ethology, and neuroethology. Karl von Frisch discovered the meanings of the waggle dance and called the communication a "dance language." Subsequent to this discovery, it has been extensively studied how effectively recruits translate the code in the dance to reach the advertised destination and how the waggle dance information conflicts with the information based on their own foraging experience. The dance followers, mostly foragers, detect and interact with the waggle dancer, and are finally recruited to the food source. In this review, we summarize the current state of knowledge on the neural processing underlying this fascinating behavior.

• Polarized skylight navigation in insects: model and electrophysiology of e-vector coding by neurons in the central complex.

  Midori Sakura, Dimitrios Lambrinos, Thomas Labhart

  Many insects exploit skylight polarization for visual compass orientation or course control. As found in crickets, the peripheral visual system (optic lobe) contains three types of polarization-sensitive neurons (POL neurons), which are tuned to different ( approximately 60 degrees diverging) e-vector orientations. Thus each e-vector orientation elicits a specific combination of activities among the POL neurons coding any e-vector orientation by just three neural signals. In this study, we hypothesize that in the presumed orientation center of the brain (central complex) e-vector orientation is population-coded by a set of "compass neurons." Using computer modeling, we present a neural network model transforming the signal triplet provided by the POL neurons to compass neuron activities coding e-vector orientation by a population code. Using intracellular electrophysiology and cell marking, we present evidence that neurons with the response profile of the presumed compass neurons do indeed exist in the insect brain: each of these compass neuron-like (CNL) cells is activated by a specific e-vector orientation only and otherwise remains silent. Morphologically, CNL cells are tangential neurons extending from the lateral accessory lobe to the lower division of the central body. Surpassing the modeled compass neurons in performance, CNL cells are insensitive to the degree of polarization of the stimulus between 99% and at least down to 18% polarization and thus largely disregard variations of skylight polarization due to changing solar elevations or atmospheric conditions. This suggests that the polarization vision system includes a gain control circuit keeping the output activity at a constant level.

• The compartment structures of the antennal lobe in the ant, Aphaenogaster smythiesi japonica.

  Midori Sakura, T Hiraguchi, K Ohkawara, H Aonuma

  Pheromones are important cues for social insects such as ants. As a first step in elucidation of pheromonal information processing mechanisms in the myrmicine ant, we investigated the morphological structure of the antennal lobe. Using autofluorescence imaging, labeling of neuronal filamentous actin, and reduced silver impregnation staining, the antennal lobe was found to consist of five compartments that, each received input from a different antennal sensory tract. Two major tracts of projection neurons, the medial and lateral antenno-cerebral tract (m- and 1-ACT), originated from a different region of the antennal lobe. The m-ACT originated from the posterior part of the antennal lobe whereas the 1-ACT originated from the anterior part. These results demonstrate a spatial segregation of function within the antennal lobe.

• De Novo synthesis of CREB in a presynaptic neuron is required for synaptic enhancement involved in memory consolidation.

  Akiko Wagatsuma, Sachiyo Azami, Midori Sakura, Dai Hatakeyama, Hitoshi Aonuma, Etsuro Ito

  Interaction between the activator type of cyclic AMP response element binding protein (CREB1) and the repressor type (CREB2) results in determining the emergence of long-lasting synaptic enhancement involved in memory consolidation. However, we still do not know whether the constitutively expressed forms of CREB are enough or the newly synthesized forms are required for the synaptic enhancement. In addition, if the newly synthesized forms are needed, we must determine the time for translation of CREB from its mRNA. We applied the methods of RNA interference and real-time polymerase chain reaction (PCR) to CREB in the cerebral giant cells of Lymnaea. The cerebral giant cells play an important role in associative learning and employ a CREB cascade for the synaptic enhancement to neurons such as the B1 motoneurons. We injected the small interfering RNA (siRNA) of CREB1 or CREB2 into the cerebral giant cells and examined the changes in amplitude of excitatory postsynaptic potential (EPSP) recorded in the B1 motoneurons. The changes in the amounts of CREB1 and CREB2 mRNAs were also examined in the cerebral giant cells. The EPSP amplitude was suppressed 15 min after injection of CREB1 siRNA, whereas that was augmented 60 min after injection of CREB2 siRNA. In the latter case, the decrease in the amount of CREB2 mRNA was confirmed by real-time PCR. Our results showed that the de novo synthesized forms of CREB are required within tens of minutes for the synaptic enhancement in memory consolidation.

• Contextual olfactory learning in cockroaches.

  Chihiro Sato, Yukihisa Matsumoto, Midori Sakura, Makoto Mizunami

  We investigated the capability of context-dependent olfactory learning in cockroaches. One group of cockroaches received training to associate peppermint odor (conditioning stimulus) with sucrose solution (appetitive unconditioned stimulus) and vanilla odor with saline solution under illumination and to associate peppermint with aversive unconditioned stimulus and vanilla with appetitive unconditioned stimulus in the dark. Another group received training with the opposite stimulus arrangement. Before training, both groups exhibited preference for vanilla over peppermint. After training, the former group preferred peppermint over vanilla under illumination but preferred vanilla over peppermint in the dark, and the latter group exhibited the opposite odor preference. We conclude that cockroaches are capable of disambiguating the meaning of conditioning stimuli according to visual context.

• Impairment of olfactory discrimination by blockade of nitric oxide activity in the terrestrial slug Limax valentianus.

  Midori Sakura, Masaru Kabetani, Satoshi Watanabe, Yutaka Kirino

  The terrestrial slug Limax readily associates an innately preferred food odor with the aversive taste of quinidine. We investigated slugs' olfactory discrimination capability among structurally similar alcohols and the effects of inhibition of nitric oxide (NO) synthesis to the olfactory discrimination behavior, using an olfactory discriminatory learning task. Limax could discriminate among the odor of 1-octanol (OT), 3-methylcyclohexanol (MC) and 1-hexanol (HX). OT was perceptually more similar to HX than was MC for them. When NO synthesis was inhibited by injecting N-nitro-L-arginine methyl ester (l-NAME) shortly before the discrimination test, slugs could not discriminate between OT and HX whereas the retrieval of olfactory memory and the discrimination between OT and MC remained intact. These results indicate that the NO cascade plays a crucial role for fine olfactory discrimination in Limax.

• Classical olfactory conditioning in the cockroach Periplaneta americana.

  Hidehiro Watanabe, Yuko Kobayashi, Midori Sakura, Yukihisa Matsumoto, Makoto Mizunami

  We established a classical conditioning procedure for the cockroach, Periplaneta americana, by which odors were associated with reward or punishment. Cockroaches underwent differential conditioning trials in which peppermint odor was associated with sucrose solution and vanilla odor was associated with saline solution. Odor preference of cockroaches was tested by allowing them to choose between peppermint and vanilla sources. Cockroaches that had undergone one set of differential conditioning trials exhibited a significantly greater preference for peppermint odor than did untrained cockroaches. Memory formed by three sets of differential conditioning trials, with an inter-trial interval of 5 min, was retained at least 4 days after conditioning. This conditioning procedure was effective even for cockroaches that had been harnessed in plastic tubes. This study shows, for the first time in hemimetaborous insects, that both freely moving and harnessed insects are capable of forming olfactory memory by classical conditioning procedure. This procedure may be useful for future electrophysiological and pharmacological studies aimed at elucidation of neural mechanisms underlying olfactory learning and memory.

• Diurnal and circadian rhythm in compound eye of cricket (Gryllus bimaculatus): changes in structure and photon capture efficiency.

  Midori Sakura, Kyo Takasuga, Mami Watanabe, Eisuke Eguchi

  Day-night changes in rhabdom size of compound eyes were investigated in three groups of crickets (Gryllus bimaculatus): nymphs and adult males and females. In both adults and nymphs, the rhabdoms were larger at night than during a day. In adults, the mean rhabdom occupation ratios (RORs) of ommatidial retinulae at midnight were about two times greater than the values at midday. This change contributes to control of the photon capture efficiency (PCE) of the eye according to photic environment. The RORs of adult males at midnight were higher than those of both adult females and nymphs. This suggests that the PCE of the compound eye of adult males is the greatest of all groups. Under constant darkness, day-night changes in ROR were detected only in adult males, but neither in adult females nor in nymphs. On the other hand, no day-night changes were detected in any experimental group under constant light. These results suggest that the change in rhabdom size between day and night is an adaptation to the photic environment that is controlled mainly by the light-dark (day-night) cycle. However, the change in male adults is induced by an endogenous circadian clock.

• 2A1-A01 Study on cricket's neuronal modeling for behavior selection : Examination of application to sweeping task of behavior selection model

  FUJII Takashi, KAWABATA Kuniaki, AONUMA Hitoshi, SAKURA Midori, SUZUKI Tsuyoshi, OTA Jun, ASAMA Hajime

  An insect generates an environmental adaptive behavior by a small brain. The authors think that such ability for environmental adaptation brings useful knowledge for behavior control of a multi-robot system. Therefore, ability for environmental adaptation of a cricket was modeled as a behavior selection model. Such ability for environmental adaptation of insects is not yet elucidated enough. Therefore, in this study, the authors discuss about an engineering application of proposed cricket's behavior selection model. In particular about this paper, proposed model was discussed and compared with other behavior selection model efficiency as an example in sweeping task.

• Foraging behavior of multiple mobile robots using fighting model in crickets

  ASHIKAGA MASATOSHI, KIKUCHI MIKA, HIRAGUCHI TETSUTARO, SAKURA MIDORI, AONUMA HITOSHI, OTA JUN

  In this paper, we propose a model of foraging behavior in multiple mobile robots. In this model, robots select behavior using their activities, which adjusted by interaction between other robots. And this model is using a mechanism of fighting behavior in male crickets. We simulate this model, and which shows that this model is better than a model of multiple robots without their activities about the working efficiency at dynamical working space.

  本研究では、コオロギの偏光定位行動と罰学習を組み合わせた新たな実験パラダイムにより、特定のe-ベクトル方向への定位を学習する際の中心複合体偏光感受性ニューロンの応答変化を調査し、ナビゲーションに関わる方向選択の神経基盤を明らかにすることを目的としている。 今年度はまずコオロギを用いた場所学習の評価を行った。モリスの水迷路学習を応用した「熱迷路」学習の実験系を確立し、特定の偏光パターンとゴールとの位置関係を学習させた。その結果、コオロギは訓練を繰り返すに従って、より早く短い軌跡でゴールにたどり着くようになった。このような行動変化は偏光パターンとゴールとの位置関係が試行ごとに変化するような条件では観察できず、彼らが偏光情報に基づいて空間を認識することが明らかとなった。また、場所学習の訓練によって空間内での探索行動パターンが変化し、より効率的な探索を行うようになることも確認できた。これらの結果はコオロギが事前の経験によって偏光刺激に対する行動を柔軟に変化させ得ることを示しており、今後の罰学習実験の基礎的データとなるものである。現在は、ナビゲーション行動の観察と脳神経細胞からの活動記録を同時に行うため、同様の実験系をトレッドミル上で再現できるように、レーザーによる熱刺激とトレッドミルの回転からクローズドループで偏光刺激を制御できるシステムを構築し、上に示したような学習行動が再現できるかどうか確認中である。


• Source of various behaviors of living things that understands from zombification of insects

  In this study, we proposed a methodology for obtaining zombie crickets that specifically and pharmacologically inhibit the function of crickets in the cranial nerve system. This zombie cricket has minimal cranial nerve function embedded in it for gait. Therefore, we sought a mathematical model of the control structure that causes the zombie cricket to walk in various places by external stimuli and produces the gait changes that may exist in the interaction of the brain, body, and environment at that time. , Tested that hypothesis with an incompetent robot.


• Cascading effects of the proximate mechanisms of host manipulation on the ecosystem energy flow

  We recently proposed the “switcher paradigm”, a framework to understand the trophic consequences of the varying degree of host-manipulation strategies used by trophically transmitted parasites. In this framework, we shed light on the sequential developmental stages of parasites switching from predation suppression to enhancement over their life histories. In this study, we tried to elucidate the proximate mechanisms of the switching strategy by examining behavior, biogenic amine and gene expressions. Furthermore, we found that arboreal mantids (Hierodula patellifera) infected by nematomorph parasites (Chordodes sp.) are attracted to horizontally polarized light, which could induce the mantids to enter the water, where the parasites must emerge to reproduce. To the best of our knowledge, this is the first study demonstrating that a manipulative parasite can take advantage of its hosts’ ability to perceive polarized light stimuli to alter host behaviour.

  本研究は、ミツバチの巣内でのコミュニケーション行動と野外での採餌飛行を継時的に観察し、その関係を解析することで、個体における空間認識の様式とそれが形成される過程を明らかにすることを目的としている。ドイツ・ベルリン自由大学との共同研究により、高調波レーダーシステムを用いて、ミツバチの野外での採餌飛行軌跡を記録をトラッキングし、採餌・コミュニケーション履歴と環境中のランドマークや餌場の質との関連を探る計画であった。 2019-2021年度にわたる新型コロナ肺炎の感染拡大のため、予定していたドイツでの野外実験は遂行できていない。そこで今年度も引き続き、これまでに同様の実験環境で取得した既存のデータを用い、巣内でのコミュニケーションと採餌飛行の履歴との解析をドイツおよび日本双方で分担してすすめた。日本側では、巣内のおよそ500個体の継続観察データを用いて、各個体のダンス行動、ダンス追跡行動および餌場訪問の履歴を網羅的に解析した。その結果、初めての餌場に訪問する場合と既知の餌場に訪問する場合とで巣内でのダンスおよびダンス追随の行動パターンに違いがあること、特に個体の初めての採餌成功の直前にダンス追随行動の顕著な増加が見られること、初採餌成功の直後から巣外活動時間の顕著な減少が見られることが明らかとなった。この巣外活動時間の減少は、探索経路の変化を反映していると考えられれることから、ドイツ側で解析中の飛行軌跡の変容を定量的に解析中である。以上の結果を総合し、個体のナビゲーションの経路選択に関わる巣内、巣外の要因について考察する予定である。

  本申請研究は、ミツバチの尻振りダンスで符号化された蜜源の方向情報を、情報受信者である追従蜂がどのように検出し、その情報を脳内でどのように解読するのかを調べるものである。今年度は、片側触角を局所被覆することで、尻振りダンスに対する追従行動にどのような影響があるかを調べることにより、追従行動の開始と持続に触角のどこからの入力が必要であるのかを評価した。具体的には、成虫羽化後のセイヨウミツバチの片側触角の鞭節先端、鞭節中央、梗節を局所被覆した個体群に加え、触角被覆なし群を用い、尻振りダンスへの追従数、連続追従数、出巣数を解析した。その結果、以下の事が分かった。 ①被覆なし群では、16～20日齢で最も尻振りダンスへの追従数、および出巣数が増加する。また、尻振りダンスへの連続追従数は、1回で終了する追従から5回以上持続する追従まで見られた。②鞭節先端被覆群は、被覆なし群に比べて追従数、および出巣数のピークが遅れた。連続追従数は、1回で終了する追従から5回以上持続する追従まで見られた。③鞭節中央被覆群は、被覆なし群に比べて追従数が減少し、 出巣数のピークが遅れた。連続追従数は、1回で終了する追従から5回以上持続する追従まで見られた。④梗節被覆群は、被覆なし群に比べて追従数、出巣数ともに低く、特に被覆なし群で最も追従数・出巣数の多かった16～20日齢で、追従、および出巣はほとんど見られなかった。連続追従数は、1回のみしか起こらず、連続追従を行わないことが分かった。これらのことから、追従開始や追従持続、さらに出巣を引き起こすための重要な入力が触角両側の梗節を通して行われている可能性が示唆された。

• Neural mechanism of the time compensation for the detection of a navigating direction using the polarized light in the honeybee

  The central complex is a crucial area in the insect brain for navigation using polarized light. Electrophysiology from the central complex exhibited that some central complex neurons responded to polarized light with a specific e-vector preference. Immunohistochemistry in the central complex was performed against iono- and metabotropic GABA receptors, and showed a different distribution between the two types of receptors. Strong positive signals for the ionotropic GABA receptor were found in the central complex while very few and fair signals were found for the metabotropic GABA receptor. This strongly suggests that ionotropic GABA receptor is dominant for information processing in the central complex compared to metabotropic receptor.

• Role of the nitric oxide signal in the information processing pathway of the insect cuticular pheromone.

  Male crickets Gryllus bimaculatus show intensive aggressive behaviors when they come across another male and start to fight each other. After the fight, the subordinate does not fight any more in his second encounter with other males, but shows escape behavior from the opponent. In this study, we aimed to clarify the neuronal mechanism underlying the aggressive behavior elicited by the cuticular substances. First, we found that the antennal input was crucial to exhibit aggressive and avoidance behavior correctly. Next, pharmacological studies showed that the nitric oxide signal suppressed aggressiveness whereas the octopamine signal enhanced. We concluded that nitric oxide and octopamine concertedly worked in the brain and controlled the aggressiveness of the male crickets.
