Abstract
The upper and lower leaf surfaces of apple and the lower leaf surfaces of pear and peach leaves were the preferred oviposition sites of the codling moth, Cydia pomonella (L.). Eggs were not deposited close to the leaf midvein or on peach fruit where pubescence was heavy. However, the density of leaf hairs was not the only physical factor affecting egg deposition. The nature of the wax scales on some surfaces also appeared to influence the number of eggs deposited.
