Abstract
Using male antenna as the sensing element three electroantennographic detection EADactive peaks were detected from pheromone gland extracts of the citrus leafminer Phyllocnistis citrella Based on gas chromatography GCmass spectrometry and GCinfrared data the semiochemicals were tentatively identified as a novel pheromone ZZE71113hexadecatrienal a previously identified attractant ZZ711hexadecadienal and Z7hexadecenal in a ratio of 30101 respectively Identification was confirmed with synthetic compounds which gave retention times identical to those of the natural products on three capillary columns with polar and nonpolar phases While traps baited only with the previously identified attractant alone did not catch any males in Brazil binary and tertiary mixtures with the major constituents caught significantly more male moths than traps baited with five virgin femalesALPP was supported by scholarships from Coordenação de Aperfeiçoamento de Pessoal de Nível Superior CAPES and the Conselho Nacional de Desenvolvimento Científico e Tecnológico CNPq in Brazil and the USA respectively This research was support in part by a gift from Fuji Flavor Co Ltd Work in Brazil was supported by FAPESP and FUNDECITRUS We thank Andres Gonzalez Paul Whetestone and Zain Syed for careful reading of the manuscript
