Identification of host volatile compounds attractive to codling moth Cydia pomonella , a most important insect of apple, will contribute to the development of safe control techniques. Synthetic apple volatiles in two doses were tested for antennal and behavioural activity in codling moth. Female antennae strongly responded to ( Z )3‐hexenol, ( Z )3‐hexenyl benzoate, ( Z )3‐hexenyl hexanoate, (±)‐linalool and E , E ‐ α ‐farnesene. Two other compounds eliciting a strong antennal response were the pear ester, ethyl ( E , Z )‐2,4‐decadienoate, and its corresponding aldehyde, E , E ‐2,4‐decadienal, which is a component of the larval defence secretion of the European apple sawfly. Attraction of codling moth to compounds eliciting a strong antennal response was tested in a wind tunnel. Male moths were best attracted to a blend of ( E , E )‐ α ‐farnesene, ( E )‐beta‐farnesene and ethyl ( E , Z )‐2,4‐decadienoate. The aldehyde E , E ‐2,4‐decadienal had an antagonistic effect when added to the above mixture.
