Abstract

The populations of Laspeyresia pomonella (L.) on two cultivars in an insecticide free orchard showed similar trends over a 12-year period. Infestation of fruit was greater on the cultivar with the larger annual crop. Predation of eggs on the cultivar Delicious was greater than on the cultivar McIntosh. Mortality of neonate larvae was greater on McIntosh. Egg-to-egg survival ratios varied from 0.23 to 6.83. The average generation survival of egg to adult for the 12-year period was near 10% which confirms an earlier value established empirically.
