【Abstract】 Comparison and analyzation of female sex pheromone that had been identified in Noctuidae suggested that the sex pheromones were composed by five types of components: esters,alcohols,aldehydes,hydrocarbons and epoxides.These chemicals had simply structure.Overlapping components exist in separate subfamilies,and with the increasing in the number of subfamily which contented sharing components,the species of insects whose sex pheromone content overlapping components increased.Sex pheromone components were highly similar among species in the same genus and largely sharing among different genera in the same subfamily.Sex pheromone components were full homology among the species in the same genera.更多还原
