Abstract
Volatile chemicals from apples collected during each of the two codling moth, Cydia pomonella, flights in central Washington were analyzed using gas chromatography coupled with electroantennal detection (GC-EAD) using serially diluted samples. More concentrated immature apple volatile chemical collections elicited significantly more antennal responses than less concentrated volatile chemical collections. Antennal responses of wild codling moths were compared to laboratory-reared moths at one concentration with no significant difference found. Four immature apple volatile chemicals elicited an antennal response at the lowest concentration and three of these were identified. These chemicals are: (Z)-3-hexenol, (d)-linalool, and (E,E)-[alpha]-farnesene. The fourth chemical eluted with the solvent peak during analysis preventing structural determination and indicating low boiling point and low molecular weight. These chemicals are of interest for understanding how codling moths use kairomones to find and select host for oviposition and, ultimately, developing attractants for female codling moths.
