Abstract

The grape beny moth, Endopiza viteana (Clemens), is the key pest of cultivated grapes in the eastern United States and Canada (Gleissner 1943; Ker 1990). Laboratory techniques have been developed for large-scale rearing of this tortricid (Taschenberg 1951, 1969) using grape berries of Vitis vinifera L. (Vitaceae) and locally grown varieties. The use of grape berries is unsatisfactory because berries attract fruit flies, develop mold, and rot rapidly at normal laboratory temperatures (Taschenberg 1969). In this paper, we describe a diet for rearing E. viteana and the process that was undertaken in its development.
