Abstract

The relative susceptibilities of 43 cowpea varieties to damage by Cydia ptychora (Meyrick) under chemical protection with monocrotophos, were investigated in field trials at Ile-Ife, Nigeria. The results revealed significant varietal differences, with the moderately resistant varieties ER-7, BPL-3-1 and EW/1 consistently showing relatively low damage. These varieties may be useful in planning an integrated pest management programme involving minimum insecticide treatment.

Résumé

Les susceptibilités relatives de 43 variétés de pois dolique vis-à-vis des dégâts causés par Cydia ptychora (Meyrick), sous protection chimique par le monocrotophos, ont été étudiées au cours de différents essais en campagne à Ile-Ife au Nigeria. Les résultats ont mis en évidence des différences significatives selon les variétés, les variétés modérément résistantes ER-7, BPL-3–1 et EW/1 subissant des dégâts relativement faibles. Ces variétés pourraient s'avérer utiles dans la planification d'un programme intégré de contrôle des parasite ne comprenant qu'un traitement minimum par insecticide.
