Vers la sélection de plantes de service pour une gestion agroécologique des pucerons en culture de melon

Abstract : Aphids are serious pests in melon crops inducing important direct damages. Besides, it is the main vector of melon viruses and can indirectly induce massive epidemics. Chemical management shows its limits and current alternative methods are not efficient enough yet, especially in field. To control aphid populations and reduce the use of chemicals at the same time, diversification of agroecosystems is a main work axis. It aims to favour natural crop-beneficial biotic interaction mechanisms, convertible in aphid management tools. In this context, this study takes particular interest in chemical ecology through repellent plants, and in biological conservation with the implementation of flower strips. It aims to characterise eleven plant species according to the behaviour of three aphid species and four main melon viruses. Thus this work focuses on the detection of potential repellent companion plants, and evaluates eventual side effects induced by each plant within melon crop. The results lead to preselect some plants to use in chemical ecology and/or within flower strips; some other plants appeared to be unsuitable.
