Diapetimorpha introita

Indication of a sex attractant has also been obtained for the noctuid pupal parasitoid Diapetimorpha introita (Ichneumonidae). Antennae from D. introita males gave EAG responses to diethyl ether extracts of female head, thorax or abdomen. Antennae from females did not respond to this chemical signal and male extracts elicited no activity. This suggested the presence of an extractable female-produced pheromone, to which the males respond. While live females were able to attract males, extracts were not active. This may be due to very low levels of biologically active material in the extracts [57].
