Host selection, reproductive biology, host-specific development and mortality of the codling moth, Cydia pomonella (L.) (Lepidoptera: Torticidae), in apple and pear

Creator:

Marti, Santiago Marti

Abstract:

The biology and behavior of the codling moth, Cydia pomonella (L.), was studied to determine factors responsible for differences in susceptibility to moth damage among apple and pear cultivars. In release experiments, codling moth adults were intercepted in significantly greater numbers in host (apple, pear) than in non-host (maple) trees,...

An individual tree is taken to be the community habitat with arthropod subcommunities developing on leaf, fruit and...
