Abstract

The behavioural responses of Goniozus legneri were investigated in a six-arm olfactometer. Among the different odours examined, carob moth (Ectomyelois ceratoniae Zeller) frass elicited the highest olfactory responses, while Ephestisa larvae, which were less suitable hosts, elicited the lowest response. The different preferences to various odours suggest that Goniozus legneri can discriminate among suitable and less suitable insect hosts.
