摘要
Extracts of newly emerged virgin females and newly emerged virgin males of the parasitic wasp ltoplectis conquisitor were highly active in eliciting sexual behavior in older males. Newly emerged males did not respond to the extracts. A reliable biological assay was devised in which the responses of males to extract could be evaluated under varying conditions. Optimum male responses to female extract were obtained at 27 degrees C and at 1.0 female equivalents (the amount of pheromone extractable from the body surface of a female). A decrease in sexual response was observed when males were repeatedly exposed to pheromone. Males also learned to associate bioassay conditions with the presence of pheromone.
