Abstract
Pheromone dispenser reduced significantly catches of male moths of spodoptera littoralis by 95% during the period from June to September than in the untreateed fields. Egg-masses were less frequent in the treated fields than in the untreated ones. The highest reduction in egg-masses occurred at the center of treated fields, and gradually decreased towards the periphery of the ex­perimental area.
