Resumen:
We studied the behavioural and electrophysiological responses of drosophilid parasitoids to
volatiles from SWD-infested strawberries. Fruit volatiles were analysed by GC-MS and evaluated by GC-EAD
with antennae of Trichopria anastrephae (Hymenoptera: Diapriidae) and Leptopilina boulardi (Hymenoptera:
Figitidae). Behavioural responses were studied for T. anastrephae by olfactometry bioassays. Both parasitoid
species showed consistent EAD responses to common fruit esters that were more prominent in volatiles from
SWD-infested fruit, in comparison with healthy fruit. In behavioural studies, T. anastrephae females showed
clear preference for fruit odours from SWD-infested strawberries over odours from healthy fruit. These results
are the first report of GC-EAD responses of potential SWD parasitoids to host-associated chemical cues.
