Abstract Solutions of 0.1%, 0.2% and 0.4% α-Tomatine were tested respectively on larvae of Pieris rapae crucivora Boisduval by spraying on the cabbage leaves used as an antifeedant. In the no-choice test or choice test, solutions of α-Tomatine showed slight or strong inhibitory activities on the feeding of larvae.
