项目摘要
We plan to study the biosynthetic origin, sensory reception, neuronal processing and behavioral effect of multi-modal signals and cues in 5 insect species that offer particularly intriguing research opportunities, as follows: (1) Having recently shown that bed bugs use a unique 6-component aggregation pheromone, we will test the hypothesis that 4 components stem from biosynthetic precursors in human blood. (2) Honey bees can sense local geomagnetic fields. We will test the hypothesis that the bees' magnetic sense is based on single-domain ferromagnetic particles and plays a crucial role in their life history. (3) Bilateral symmetry with paired sense organs is common in all animals that depend on a comparison between left and right sensory input to locate prey or mates. We will test the hypothesis that the short-lived males of the strepsipreran Xenos peckii can "map" even a "3-dimensional odor space" when seeking a mate in a mobile host wasp. In high-speed films, we noticed that males project the branches of their bifurcated antennae in all directions. If, as predicted, olfactory receptor neurons from each antennal branch were to converge onto separate primary olfactory centers in the brain, then males could form a 3-dimensional "road map" to the microlocation of a mate. (4) In eusocial insects, individuals give up reproduction to help rear offspring of relatives. One explanation for this reproductive altruism emphasizes costs and benefits. Taking photo- and thermographs of a paper wasp nest, we noticed one wasp being much warmer than her nest mates. This "hot" wasp may have been the nest's guard on high alert to mount an immediate attack if needed. We will test the hypothesis that wasps save energy by assigning the energetically-costly guarding duty to few select nest mates. (5) Host and mate recognition cues between parasitoid wasps at the 3rd and 4th trophic level have hardly been studied. We have recently shown that males of Pimpla disparis, a primary parasitoid of gypsy moth (pre)pupae, sense parasitized pupae, memorize their location, visit them frequently, track developmental progress, and arrest on them when a prospective mate (PM) nears emergence. Both females and males of Theronia atalantae, a hyperparasitoid of P. disparis, also arrest on gypsy moth pupae parasitized by P. disparis, suggesting that both female and male T. atalantae, like male P. disparis, respond to sound and vibratory cues from a prospective host or mate inside a gypsy moth pupa. We will test the hypotheses that (a) female T. atalantae rely on vibratory host cues to sense gypsy moth pupae parasitized by P. disparis; (b) male T. atalantae exploit characteristics of vibratory cues to discern between gypsy moth pupae containing a P. disparis pre-pupa or a prospective T. atalantae mate; and (c) P. disparis PMs discern between the cues associated with a visiting P. disparis male (prospective mate) and a T. atalantae female (prospective enemy).
我们计划在5种昆虫中研究多模态信号和线索的生物合成起源、感觉接收、神经元加工和行为效应,这提供了特别有趣的研究机会,如下:(1)最近发现臭虫使用独特的6组分聚集信息素,我们将测试4组分来自人类血液中的生物合成前体的假设。(2)蜜蜂可以感知当地的地磁场。我们将测试蜜蜂的磁感觉是基于单畴铁磁颗粒的假设,并在它们的生活史中起着至关重要的作用。(3)具有成对感觉器官的双侧对称性在所有依赖左右感觉输入之间的比较来定位猎物或配偶的动物中是常见的。我们将测试的假设,即短寿命的男性的Strepsipreran Xenos peckii可以“映射”,甚至是“三维气味空间”时,寻求伴侣的移动的主机黄蜂。在高速摄影中,我们注意到雄性向各个方向伸出分叉的触角。如果像预测的那样,来自每个触角分支的嗅觉感受器神经元会聚到大脑中不同的初级嗅觉中心,那么雄性就可以形成一个三维的“路线图”,以确定配偶的微观位置。(4)在真社会性昆虫中,个体放弃繁殖以帮助抚养亲属的后代。对这种生殖利他主义的一种解释强调成本和收益。我们对一个纸做的蜂巢进行拍照和温度记录,注意到一只黄蜂比它的同伴要暖和得多。这种“热”黄蜂可能是巢穴的守卫,处于高度戒备状态,如果需要,可以立即发动攻击。我们将测试的假设,黄蜂节省能源分配精力昂贵的警卫职责,以少数选择巢队友。(5)寄生蜂在第3和第4营养级之间的寄主和配偶识别线索的研究还很少。我们最近表明,男性的丘疹,主要寄生的舞毒蛾(前)pupelies,感寄生pupelies,记住他们的位置,经常访问他们,跟踪发展的进程,并逮捕他们时,准伴侣(PM)接近出现。舞毒蛾的重寄生蜂-像雄性的P. tagiis一样,atalantae对来自舞毒蛾蛹内潜在宿主或配偶的声音和振动信号做出反应。我们将测试的假设,(a)女性T。(B)雄蛾通过振动信号感知寄生于舞毒蛾的舞毒蛾; atalantae利用振动线索的特征来辨别含有P. dalanis预蛹的舞毒蛾蛹或潜在的T.(c)P. atalantae交配;和(c)P. tagliis PM辨别与来访的P. tagliis雄性(预期交配)和T. atalantae female(prospective enemy).
