Book excerpt: "The currant fruit fly, Epochra canadensis Loew, a native insect, is an important factor limiting the production of currants and gooseberries in the greater part of Canada, and in parts of the United States of America. Studies have shown this insect to be vulnerable in the adult stage to stomach and contact insecticides. Investigations to control the adult fly with contact and stomach insecticides have culminated in the recommendation of DDT (Andison et al 1951). The possible destruction of the maggot and emerging adult with contact insecticides, and the immobile pupae with soil fumigants, has received attention by some workers, but without any notable success. The development of newer soil fumigants and insecticides has provided opportunity for further study on this phase of the control problem. The present paper presents results obtainad from the use of the fumigants ethylene dibromide and DD and the insecticides BHO and dieldrin, tested in the laboratory, against dormant currant fruit fly pupae, and the insecticides BHC, DDT, and chlordane, tested in the laboratory, against the larvae entering the soil. The fumigant ethylene dibromide was further tested in the field against dormant, prediapausing and diapausing pupae at different rates, depths, and under conditions of cultivation and no cultivation. The affect of the soil temperature and soil moisture on the efficacy of ethylene dibromide was considered. ..."--
