Unravelling chemical cues used by Diachasmimorpha longicaudata (Hymenoptera: Braconidae ) during host search

Abstract

Parasitoid wasps are attracted to their hosts using associated volatile compounds. In an static air olfactometer, it was shown that Diachasmimorpha longicaudata females oriented towards oranges with direct or indirect signs of infestation with host larvae, The identification of attractive volatile compounds will allow the development of effective baits for population monitoring in IPM programs. Aim: To confirm previous results using a dynamic olfactometer and to identify relevant volatile compounds related to wasp attraction
