Sterilization of the Cabbage Maggot with Apholate

Abstract

Adults of the cabbage maggot, Hylemya brassicae (Bouché), were sterilized and oviposition was reduced when apholate was introduced into their diet of 10% sugar solution. Concentrations of 1.0% apholate fed for 24, 48, and 72 hours to females suppressed oviposition by 50, 75, and 90%, respectively. Males were sterilized in certain treatments by a 24-hour ad lib. feeding period on 0.5:1 prolate. They were sterilized also by a single feeding of 1.25%.
