Characterization 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 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 کاملUse of micro-CAT scans to understand cowpea seed resistance to Callosobruchus maculatus
The cowpea bruchid, Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae: Bruchini), is a worldwide pest of stored cowpea grain [ Vigna unguiculata (L.) Walp. (Leguminosae)], causing tens of millions of dollars’ worth of damage annually. One method of managing this pest involves planting cultivars whose seeds are resistant to bruchids. Despite extensive research, we still do not know the me...
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 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...
