项目摘要

Social insects are among the most ecologically dominant terrestrial animals. Their success is largely attributed to division of labor among the workers that make up their colonies. Individual differences in worker behavior are governed by physiological and anatomical changes in the nervous system, particularly in the brain. However, the dynamic properties of brain neurons that influence worker behavior are poorly understood. The goal of this project is to study how changes in brain neurons are associated with division of labor among social insect workers, focusing on neural plasticity in the mushroom bodies (MB). MB are structures in insect forebrains that are involved in learning and sensory integration, and the MB may play an important role in regulating division of labor. As a first step toward understanding the evolution of MB effects on behavior, the relationships of MB neuroanatomy and worker behavior will be compared between a wasp species with small, simple societies (Mischocyttarus mastigophorus) and a species with larger, more complex colonies (Polybia aequatorialis). Three main approaches will be used. In the first study, MB neurons that are associated with individual differences in task performance will be identified. In the second study the effects of age on MB neuron plasticity and worker behavior will be measured. In the third study, colonies will be manipulated to induce changes in worker behavior, and associated neural changes will be measured. The proposed projects include graduate and undergraduate training opportunities, and will provide inter-institutional training experiences. They will also promote education for Americans and local residents in Costa Rica, including biology guides (Monteverde Cloud Forest Reserve), and students on graduate and undergraduate field courses. Ongoing investigations in Monteverde will enhance the visibility of basic investigation at this important tropical research and conservation site. The research findings may also have relevance to the control/management of social insect pests and beneficial insects.
社会性昆虫是最具生态优势的陆生动物之一。他们的成功很大程度上归功于组成殖民地的工人之间的劳动分工。工人行为的个体差异是由神经系统,特别是大脑的生理和解剖变化决定的。然而,影响工人行为的大脑神经元的动态特性知之甚少。该项目的目标是研究大脑神经元的变化如何与社会昆虫工人的劳动分工相关联,重点是蘑菇体(MB)的神经可塑性。MB是昆虫前脑中参与学习和感觉整合的结构,可能在调节劳动分工中发挥重要作用。作为了解MB对行为的影响的演变的第一步,MB神经解剖学和工人的行为之间的关系将比较小,简单的社会(Mischocyttarus mastigophorus)和一个更大,更复杂的殖民地(Polybia aequatorialis)的黄蜂物种。将采用三种主要方法。在第一项研究中,将确定与任务表现的个体差异相关的MB神经元。在第二项研究中,年龄对MB神经元可塑性和工人行为的影响将被测量。在第三项研究中,将操纵蜂群以诱导工蜂行为的变化,并测量相关的神经变化。拟议的项目包括研究生和本科生培训机会,并将提供机构间培训经验。他们还将促进对美国人和哥斯达黎加当地居民的教育,包括生物指南(蒙特韦尔德云雾森林保护区),以及研究生和本科生实地课程的学生。正在蒙特韦尔德进行的调查将提高这一重要热带研究和保护地点的基础调查的可见度。研究结果也可能与社会害虫和益虫的控制/管理有关。
