Antennal and Behavioral Response of Cydia pomonella and Lobesia botrana Moths to Allyl Cinnamate

Marta Giner, Mercè Balcells and Jesús Avilla

Electroantenographical (EAG) response to allyl cinnamate were assessed on virgin and mated Cydia pomonella and Lobesia botrana adults to determine whether this compound could be used within integrated management programs (IMP). Adult behavioral reaction was later assessed in a wind tunnel, with and without the main compound of the corresponding female sex pheromone. Allyl cinnamate elicited antennae responses of C. pomonella and L. botrana, both males and females. Allyl cinnamate EAG response was as high as pheromone response, and it was not reduced after mating. In wind tunnel assays, allyl ester itself was not attractive to C. pomonella males, but its presence did not interfere with the pheromonal action when the number of contacts was compared. For females, a higher proportion of codling moths moved towards the source when allyl cinnamate was in the wind-tunnel plume. No differences were recorded depending on the mating status of codling moth adults. The same trend was observed in L. botrana males and females.
Results suggest that allyl cinnamate acts as a female behavioral modifier, but more assays are required to
determine its role in insect communication in field conditions before inclusion in integrated pest management.
