鳞翅目蛾类雄性昆虫的信息素

鳞翅目雄性昆虫信息素释放器官结构及分布复杂多样。释放的信息素化学成分及其功能也复杂多样 ,具有种的特异性。求偶、避免种间交配、驱避同种雄性个体和驱避捕食者可能是雄性昆虫信息素的主要功能。性选择、生殖隔离和感觉系统利用是雄性昆虫信息素起源的 3种主要假说 ,而寄主转移和建立者物种形成可能与雄性昆虫信息素消失有关。

Research advance on the male lepidopteran pheromones

There is an extraordinary degree of diversity in both pheromone chemistry and morphology of the scent|organs from males of many species of Lepidoptera. Several functions have been postulated for the evolution of male pheromones, such as courtship, preventing interspecific mating, mating deterrent against conspecific males, predator repellent. Those hypotheses relating to the origin of the male pheromones and scent structure are sexual selection, reproductive isolation and sensory exploitation. And the loss of the male pheromones is associated with host shift and founder|effect speciation.
