Synthetic sex pheromone traps for the legume pod borer, Maruca vitrata (Fabricius) (Lepidoptera: Crambidae), effectively attracted males in cowpea fields at Cotonou (lat. 6°25' N) in southern Benin, where pest incidence is observed throughout the year. However, the same pheromone lures caught ver...
The Natural Resources Institute (NRI) and the International Institute of Tropical Agriculture (IITA) are collaborating to develop sex pheromone traps as monitoring tools for Maruca vitrata. The principal component of the pheromone is (E, E)-10, 12-hexadecadienal. Our trapping experiments in cowpe...
The legume pod borer Maruca vitrata Fabricius (Lepidoptera: Crambidae) is a serious pest of cowpea in West-Africa. The parasitoid Apanteles taragamae Viereck (Hymenoptera: Braconidae) that originates from Taiwan is a potential candidate for biological control of M. vitrata. We investigated under ...
Cowpea Vigna unguiculata (L.) Walp. is an important component in mixed cropping systems that are appropriate to the agro-ecological characteristics of the West African savannah. However, the contribution of cowpea to overall productivity of the systems is reduced by a number of insect pest specie...
The larval parasitoid guild of the cowpea pod borer Maruca vitrata was studied on wild and cultivated host plants in Southern and Central Benin, West Africa. A total of eight parasitoids, seven of which belonging to the Hymenoptera: Braconidae, and one to the Diptera: Tachinidae, were observed ex...
Une expérimentation a été conduite à Abomey-Calavi (Sud-Bénin) à l'aide d'un dispositif de blocs aléatoires complets en réalisant différents types d'association Vigna-Sesbania. Le dispositif expérimental représenté par six traitements et quatre répétitions a été installé à quatre dates de semis e...
Thedose-dependent mortality of second (3-4 days old),third (5-6 days old) and fourth (7-9 days old) larval instars of Marucavitrataas induced by the entomopathogenic fungal isolates, MetarhiziumanisopliaeMa 29 and BeauveriabassianaBb 115 was determined in a laboratory experiment. For ...
The effect of temperature on the development and survival of the legume pod borer, Maruca vitrata (Fabricius) (Lepidoptera: Pyralidae) was examined by rearing cohorts on a semi-synthetic diet containing cowpea grain and leaf at different constant temperatures in the laboratory. The developmental ...
Insecticidal lectins were isolated from 20 resistant Vigna and non‐Vigna legumes and tested againstn 3 pests of cowpea namely: Maruca vitrata, Callosobruchus maculatus and Clavigralla tomentosicollis. Crude lectins were separated from seeds using sodium chloride extraction, ammonium sulfate fract...
