构筒天牛交配行为生物学和性信息素的研究

STUDY ON THE MATING BEHAVIOR AND THE SEX PHEROMONE OF LONG-HORNED BETTLE,Oberea fuscipennis V rufotestasea Pic.(Coleoptera:Cerambycidae)

对构筒天牛成虫的交配行为的观察研究表明,化学信息是构筒天牛成虫两性活动的主要通讯方式,雄虫的视觉和机械感觉对异性的辨识并不重要。雌虫经特殊腺体分泌,释放挥发性化合物,通过空气传递给雄虫,从而完成突配。这种中距离作用的化学信号物质,与构筒天牛成虫善飞行但不善爬行的习性相适应,保证了异性的寻找和交配的顺利进行。

This paper deals with the mating behavior and the male responses tofemale body extraction in long-horned beetle,Oberea fuscipennis Vrufotestasea Pic..In the communication between two sexes,the chemicalfactor is most important while the visual and mechanical senses of malebeetles perform less function on female recognition.Under the guidanceof sex pheromone relased by gland or female body,male beetles Can findfemales and copulate with them.This kind of chemical signal materialfunctioning in middle distance adapts to the flying and crawling behavio-ries in the mating of the beetle.
