Abstract
Pickleworm (Diaphania nitidalis Cramer) is a major pest of cucurbits. This study investigated the potential of using squash (Cucurbita pepo L.), as a trap crop and watermelon (Citrullus lanatus [Thunb.] Matsum. & Nakai) as an intercrop in a push-pull cropping approach to manage pickleworm on cantaloupe (Cucumis melo L.). A series of oviposition and larval preference experiments were conducted. Females preferred to lay their eggs on a squash plant, to a watermelon or cantaloupe plant when presented with all three. Females were not averse to laying their eggs on watermelon; though the non-cucurbit, bean, stimulated reduced oviposition. While neonate larvae may be capable of moving between plants they do not have a feeding preference between squash, cantaloupe, or watermelon. Overall squash has the potential to be an effective trap crop, however a non-cucurbit, such as bean, would be better suited than watermelon as a potential intercrop in this system.
