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 کاملCharacterization of cowpea genotype resistance to Callosobruchus maculatus
The objective of this work was to characterize the resistance of 50 cowpea (Vigna unguiculata) genotypes to Callosobruchus maculatus. A completely randomized design with five replicates per treatment (genotype) was used. No‐choice tests were performed using the 50 cowpea genotypes to evaluate the preference for oviposition and the development of the weevil. The genotypes IT85 F‐2687, MN05‐841 B...
متن کاملAntagonistic Regulation, Yet Synergistic Defense: Effect of Bergapten and Protease Inhibitor on Development of Cowpea Bruchid Callosobruchus maculatus
The furanocoumarin compound bergapten is a plant secondary metabolite that has anti-insect function. When incorporated into artificial diet, it retarded cowpea bruchid development, decreased fecundity, and caused mortality at a sufficient dose. cDNA microarray analysis indicated that cowpea bruchid altered expression of 543 midgut genes in response to dietary bergapten. Among these bergapten-re...
متن کاملResistance of legume seeds to the bruchid, Callosobruchus maculatus: metabolites relationship.
A study was initiated to categorize the seeds of various wild and cultivar legume varieties on the basis of their relative resistance to the bruchid, C. maculatus, and to correlate the important primary and secondary metabolites (non-protein anti-metabolites) in these seeds to the developmental parameters of the bruchid. In general, the wild seed varities showed greater amount of resistance to ...
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 ...
