基本信息

项目摘要

Social insects feature highly complex interactions that add to their enormous ecological impact and success. Chemical communication plays an important role in task sharing and regulation of reproduction. In the bumblebee Bombus terrestris (Hymenoptera: Apidae) the development of worker ovaries and worker reproduction is inhibited by a primer pheromone of the queen as well as so-called signals of fertility. The queen uses both chemical signals to uphold reproductive dominance and thus maintain the social structure of the annual colonies. A characteristic of B. terrestris colonies are two distinct stages of reproductive regulation. In the initial stage the queen is the only reproductive female within the colony. After the so called “competition point” dominant workers with developed ovaries compete with their queen and other workers for the production of male offspring. Despite extensive research, it is still unknown how certain workers overcome the pheromonal inhibition of ovarian development. The aim of this project is to investigate the role of different endogenic and exogenic factors that are suggested to influence the reproductive behaviour of workers in B. terrestris. An integrative approach including chemoecological, neurophysiological, endocrinological and morphological methods will be applied to determine the physiological mechanisms and/or ecological factors that influence the individual decision of a bumblebee worker to lay eggs or not and thus its performance of social tasks.
社会性昆虫具有高度复杂的相互作用,增加了它们巨大的生态影响和成功。化学通讯在任务分配和生殖调控中起着重要作用。在熊蜂熊蜂terrestris(Hybritera:蜜蜂科)的发展,工人卵巢和工人的生殖抑制的引物信息素的女王,以及所谓的生育信号。蚁后利用这两种化学信号来维持繁殖优势,从而维持一年生蚁群的社会结构。B的特征。terrestris群体是生殖调节的两个不同阶段。在最初的阶段,女王是殖民地内唯一的生殖雌性。在所谓的“竞争点”之后,卵巢发达的占优势的工蜂与它们的蜂王和其他工蜂竞争生产雄性后代。尽管进行了广泛的研究,但仍然不知道某些工人如何克服卵巢发育的信息素抑制。该项目的目的是调查不同的内源性和外源性因素的作用,这些因素被认为会影响B中工人的生殖行为。terrestris。本研究采用化学生态学、神经生理学、内分泌学和形态学等综合研究方法,探讨影响工蜂个体产卵行为的生理机制和/或生态因素。
