Varietal 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 کاملInsecticidal effect of silica and silver nanoparticles on the cowpea seed beetle, Callosobruchus maculatus F. (Col.: Bruchidae)
Nanotechnology has become one of the most promising new approaches for pest control in recent years. In our screening program, laboratory trials were conducted to determine the effectiveness of silica nanoparticles (SNP) and silver nanoparticles (AgNP) on larval stage and adults of Callosobruchus maculatus on cowpea seed. Nanoparticles of silica and silver were synthesized through a solvotherma...
متن کاملOviposition decisions in the seed beetle, Callosobruchus maculatus (Coleoptera: Bruchidae): effects of seed size on superparasitism
The seed parasite Callosobruchus maculatus generally disperses eggs uniformly among seeds. We used cowpeas (Vigna unguiculata) of two class sizes (large and small) to test predictions based on a simple resource threshold model that females will distribute eggs among seeds in a manner that maximizes the amount of resources allocated to each offspring. When females were presented with multiple se...
متن کاملCondition dependence of male and female genital structures in the seed beetle Callosobruchus maculatus (Coleoptera: Bruchidae).
Theory predicts that costly secondary sexual traits will evolve heightened condition dependence, and many studies have reported strong condition dependence of signal and weapon traits in a variety of species. However, although genital structures often play key roles in intersexual interactions and appear to be subject to sexual or sexually antagonistic selection, few studies have examined the c...
متن کاملThe seed coat of Phaseolus vulgaris interferes with the development of the cowpea weevil [Callosobruchus maculatus (F.) (Coleoptera: Bruchidae)].
We have confirmed here that the seeds of the common bean (Phaseolus vulgaris, L.) do not support development of the bruchid Callosobruchus maculatus (F.), a pest of cowpea [Vigna unguiculata (L.) Walp] seeds. Analysis of the testa (seed coat) of the bean suggested that neither thickness nor the levels of compounds such as tannic acid, tannins, or HCN are important for the resistance. On the oth...
