RESPONSE OF THE APPLE MAGGOT, RHAGOLETIS POMONELLA, AND THE CHERRY FRUIT FLY, R. FAUSTA (DIPTERA: TEPHRITIDAE), TO PROTEIN HYDROLYSATE BAIT SPRAYS

摘要

None of five mixtures of protein hydrolysate and azinphosmethyl which were applied as foliar sprays (1.0, 2.0, 5.0% yeast hydrolysate, 2.0% corn hydrolysate, and 2.0% soy hydrolysate) killed significantly more apple maggot flies, Rhagoletis pomonella, or black cherry fruit flies, R. fausta, than a spray of azinphosmethyl alone which was used as a control. This suggests that hydrolysate bait sprays would be no more effective than a toxicant alone in controlling these flies
