四川短尾鼩是其分布区内的农田小型害兽，其数量升高严重困扰着我国有害生物的防治。该动物最明显的特征是散发出浓烈的“臭味”，其生物学功能尚未可知。化学通讯是目前动物行为学研究的热点，但该领域食虫目的研究却非常稀缺。本项目采用野外测试、行为学、神经内分泌学、分子生物学、GC-MS化学分析的方法，系统地研究四川短尾鼩气味腺的性别差异、季节动态、发育特点、组织变化等生物学特征；确定气味的来源、个体识别、性别识别、社会等级、种内种间关系调节的行为功能；测定气味信息素的化学成分、下丘脑c-fos基因表达。通过研究，掌握该动物气味的基本行为功能，揭示其气味信息素的作用机制，探讨气味信号对种群数量的影响富有创新性，本研究对于四川短尾鼩等小型害兽防治的新型引诱剂开发具有重要的应用前景，是对国际食虫目气味研究的重要补充，也将开辟我国食虫目气味的全新研究，推动哺乳动物化学通讯的研究和完善种群调节理论。

The mole-shrew（Anourosorex squamipes ）is a kind of small farmland harmful mammal in its distribution area. The increase of its population number seriously plagued the pest control in our country for a long time. The most obvious characteristic of Anourosorex squamipes is releasing the “stink”. However, the biological function of the odor is still poorly understood. At present chemical communication is the research hotspot of animal behavior, but similar researches in the insectivores are scarce. In the project, we will systematically study sex differences, seasonal dynamics, development characteristics, micro-structural change of the odor glands in the Anourosorex squamipes. The methods including field experiments, behavioral research, neuroendocrine, molecular biology, chemical analysis GC-MS. We aim to dissect the behavioral functions of the odor on conspecific recognition, sex recognition, social status, intra- and inter-specific interactions. In addition, the source, chemical constituents，c-fos gene expression on the odor will be investigated. We hope to understand the basic behavior functions of the odor of the Anourosorex squamipes and reveal mechanisms of neuromodulation of the odor pheromone. Finally, the influences of the Anourosorex squamipes odor signal on population variation will be analyzed. This research has an important application prospect about the new attractants development for the Anourosorex squamipes and other pest control, and it will be supplementary to the studies on the odor signals of insectivora. Furthermore, it would promote the studies on mammals chemical communication and population regulation.
