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...
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...
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 ...
The effect of four host plant species of the herbivore Maruca vitrata Fabricius (Lepidoptera: Crambidae) on development time, longevity, fecundity and sex ratio of the parasitoid Apanteles taragamae Viereck (Hymenoptera: Braconidae) was investigated under laboratory conditions. The larvae were pa...
Apanteles taragamae Viereck is a larval parasitoid introduced in Benin for classical biological control of the cowpea pod borer Maruca vitrata Fabricius. In the laboratory, we evaluated the effects of A. taragamae on non-target herbivore species, and on another parasitoid of M. vitrata, i.e. the ...
