Abstract

Excerpts from the report: The grape berry moth, a small brownish moth, is a major pest of grapes over most of the Eastern United States. Damage by the grape berry moth to grapes can be greatly reduced by following certain cultural control practices. In general, they include using tillage implements to bury overwintering cocoons under a layer of soil. The moths, therefore, are unable to make their way out in the spring. They die without reaching the grapevines to lay their eggs. Although cultural control practices cannot be expected to eliminate the grape berry moth, they will reduce the amount of injury it causes. They affect only the first brood, but any reduction in the first brood will reduce the numbers in the second brood. Thoroughness and timeliness in carrying out these practices are essential.
