About the Book

Les objectifs spécifiques ont été de connaitre la diversité biologique, des insectes ravageurs dans le périmètre irrigué de Maga ainsi leur répartition par stade phénologique. De voir l'effet de l'extrait aqueux de fruit de neem sur les insectes ravageurs, par variété et en fonction des stades phénologiques. D'évaluer les dégâts d'insectes pendant le tallage en fonction des variétés. D'évaluer les pertes dues aux foreurs de tiges pendant la récolte. L'étude a été menée sur deux variétés de riz, la variété de riz IR46 et NERICA3 selon un dispositif expérimental en split-splot. La capture des insectes s'est faite à l'aide d'un sweep net. Les clés d'identification des insectes d'Heinrich (1993), Hill (1983), Heinrichs et Barrion (2004) et la clé de reconnaissance des familles de Delvare et Aberlenc (1989) ont permis d'identifier les insectes capturés.Il ressort de l'inventaire que la culture du riz héberge vingt-quatre espèces d'insectes, appartenant à dix-neuf familles, reparties dans sept ordres. Treize insectes ont le statut de ravageurs. La lutte biologique s'est montrée efficace en pépinière au tallage, et à réduire les insectes ravageurs considérablement en épiaison.
