The interactions between the cowpea aphid Aphis craccivora Koch, its parasitoid Lysiphlebus testaceipes Cresson and hyperparasitoid Syrphophagus africanus Gahan were assessed in the laboratory. Host age preference for hyperparasitism was evaluated using parasitized aphids of different ages (i.e. ...

The incidence of the key insect pest of cowpea (Vigna unguiculata L. Walp), the legume pod borer Maruca vitrata F., was investigated with light trap in the Sudano-Sahelian zone of Niger in 2014 and 2015. The results revealed that the first larvae appeared in August (0.03 ± 0.03 to 2.48 ± 0.32 lar...

Studies were conducted on the population fluctuations of the cowpea pod weevil, Piezotrachelus varius on cowpea at Melong, NY(lkon and Babessi, and the susceptibility of seeds of selected cowpea cultivars to its damage in the western derived savanna zone of Cameroon, during the 1999 and 2000 cowp...

Les insectes ravageurs constituent une contrainte importante à la production du niébé au Burkina Faso. La présente étude visait à fournir aux producteurs une stratégie de lutte intégrée combinant la résistance variétale vis-à-vis de Clavigralla tomentosicollis Stäl et des pulvérisations d’amandes...
Insect pests are important constraints to cowpea production in central Burkina Faso. The main goal of this study was to provide an IPM strategy based on combination of resistant varieties to the pod sucking bug, and the application of neem seed extract against flower thrips (Megalurothrips sjoste...

Plants damaged by herbivores are known to release odors attracting parasitoids. However, there is currently no information how leguminous plants damaged by the pod borer Maruca vitrata attract the exotic larval parasitoid Therophilus javanus, which was imported into Benin from the putative area o...
Cowpea is a widely cultivated and major nutritional source of protein for many people that live in West Africa. Annual yields and longevity of grain storage is greatly reduced by feeding damage caused by a complex of insect pests that include the pod sucking bugs, Anoplocnemis curvipes Fabricius ...

The population dynamics of major cowpea pests was studied in northern Nigeria during 1992-95 in both the wet and dry seasons. Rainfall cowpea is grown as a subsistence crop, mixed at low densities with cereals. Dry-season cowpea is irrigated or grown on residual moisture in monocultures as a cash...
