狄斯瓦螨是蜜蜂的重要寄生性害螨，严重制约养蜂业的发展。国内外研究表明，狄斯瓦螨在蜂箱黑暗的环境中具有选择性寄生蜜蜂幼虫和雄蜂等行为，而这种寄主选择行为主要受蜜蜂化学感受物质和体表化合物的介导。然而，对于狄斯瓦螨的嗅觉感觉机制，特别是介导化合物的种类和化学感觉生理尚没有相关研究报道。 本项目拟采用挥发物原位化学分析等技术探明蜜蜂各虫态信息素及体表化合物组成；结合寄主选择行为反应和电生理测定，明确主要的介导化合物种类；采用昆虫生理学技术，明确狄斯瓦螨嗅觉感受部位、感受器结构与分布及对介导化合物的行为反应剂量效应，最终阐明狄斯瓦螨选择性寄生蜜蜂的化学感觉机制。 本研究对丰富昆虫（螨）寄主选择行为生理具有重要的理论意义，对蜜蜂害螨行为调控剂和螨害控制技术的研发具有重要的实用价值。

Varroa destructor is known to be the most serious ectoparasitic of Apis mellifera and has become the most significant economic threat to apiculture on a global scale. Domestic and foreign research indicates that Varroa destructor select parasitism-host of the Honeybee in the dark hive, that parasitic select drone and larvae. The honeybee pheromones and surface compounds mediated parasitic behavior.However, Olfactory mechanisms of Varroa destructor have not research report that mediate the kinds of chemical compound and physiology of olfactory. Our research adopts Volatiles in situ analysis to detect the state of The Honeybee pheromone and theSurface compounds of body. combined with the host selection behavior response and electrophysiological recording.The research indicate chemical compound.and Position, structure and distribution of olfactory of Varroa destructor. The study can rich physiology of insect ( mite ) host selection behavior in theory. The research will make for the behavior regulation agent of Varroa destructor and pest control technology .
