Genetic variability and resistance of cultivars of cowpea [Vigna unguiculata (L.) Walp] to cowpea weevil (Callosobruchus maculatus Fabr.).
The cowpea weevil (Callosobruchus maculatus Fabr.) is the most destructive pest of the cowpea bean; it reduces seed quality. To control this pest, resistance testing combined with genetic analysis using molecular markers has been widely applied in research. Among the markers that show reliable results, the inter-simple sequence repeats (ISSRs) (microsatellites) are noteworthy. This study was pe...
متن کاملFunctional Response of Dinarmus Basalis (rond.) (hymenoptera: Pteromalidae) Parasitizing Callosobruchus Maculatus (f.)
The functional response of the parasitoid Dinarmus basalis (Rond.) (Hymenoptera: Pteromalidae) is determined to evaluate its potential as a biological control agent. Four female wasps in the presence of males parasitoids, were allowed to oviposit during their life span or hosts at different densities. The data were fit by Rogers′ (1972) parasitoid model. The rate of parasitoid search was a′= 0....
متن کاملVarietal Susceptibility Of Cowpea (Vigna Unguiculata L.) To The Storage Beetle, Callosobruchus Maculatus F. (Coleoptera: Bruchidae)
Twenty-two cowpea genotypes, comprising eighteen elite lines from the CSIR-Savanna Agricultural Research Institute, and three improved cultivars from the International Institute of Tropical Agriculture were evaluated for their susceptibility to infestation and damage by the storage beetle, Callosobruchus maculatus F. The assessment of their relative susceptibilities was based on oviposition, me...
متن کاملGenetic Distribution of the Cowpea (Vigna Unguiculata (L.) Walp) Bruchid (Callosobruchus Maculatus F., Coleoptera, Bruchidae) Populations in Different Agro-Ecological Areas of West Africa
Cowpea [(Vigna unguiculata L.) Walp. (Fabaceae)] is the most important food legume grown throughout West Africa. The seeds of this legume protein source are the least expensive for most African populations. However, cowpea production is severely limited by the losses (60-70%) caused by Callosobruchus maculatus F. (Coleoptera: Bruchidae). Whereas many studies have been devoted to the ecology of ...
