Pubescence as a Factor in Codling Moth, Oviposition, and Fruit Entry in Five Apple Selections

Significant differences (P = 0.05) in fruit infestation by codling moth larvae were found when fruit of 5 apple selections, with different levels of leaf pubescence, were evaluated. No differences in entry into fruit were found when larvae were placed on the relatively glabrous upper leaf surface. Selections having a pubescent lower leaf surface had significantly (P < 0.05) reduced numbers of entries. Females allowed to oviposit freely on fruit and leaves preferred to oviposit on the glabrous upper leaf surface. In all but one selection, more eggs were laid on the leaves than on the fruit. About 70% of larval entries were found in the midsection of the fruit, with 14% and 15% occurring at the calyx and stem ends, respectively. Larval entry was increased on the side of the fruit closest to the light source. Leaf pubescence seems to be a factor in 1st brood codling moth preference of apple cultivars.
