In laboratory studies, the compound avermectin B, (MK-936) was biologically active against Anthonomus grandis grandis Boheman. The activity was expressed by arrested pupal-adult development when avermectin B1 was topically applied to newly ecdysed pupae. Depending upon the concentration applied, metamorphosis progressed to a given point in morphogenesis and then death occurred. Avermectin B1 significantly reduced pheromone production when applied topically to adults. Additional effects were observed on adults after immersion or by their feeding upon treated cotton buds. Paralysis developed and death occurred at ca. 14 days postexposure. A swollen, distended abdomen extending beyond the elytra was a characteristic symptom of avermectin B1 activity.
