LABORATORY BREEDING OF ASCOGASTER CARPOCAPSAE VIER. WITH NOTES ON BIOLOGY AND LARVAL MORPHOLOGY

Abstract

Ascogaster carpocapsae Vier. was not known to have spread naturally over the mountain barriers into the apple growing districts of British Columbia, and it was considered that the introduction of this species might aid in the control of the codling moth (Cydia pomonella Linn.) which has become a serious pest in that area during recent years.
