Insecticidal 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 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 کاملEvaluation of the powder of Piper guineense and pirimiphos- Methly F for the control of cowpea beetle Callosobruchus maculatus (F.)
Cowpea is major source of dietary protein in tropical region of the world and damage caused by Callosobruchus maculatus impact negatively on its economic and nutritional values. In Nigeria today, the use of synthetic insecticides has been the major means of protecting stored grains from insect pest infestation. The drawback associated with the use of insecticides has necessitated the search for...
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...
متن کاملComparative efficacy of seven plant products on the cowpea burchid, Callosobruchus maculatus F. development and damage
An experiment was conducted to investigate the insecticidal activities of seven plant materials (1-5g/100g cowpea seeds) namely: citrus peel powder (CPP), Acacia leaf powder (ALP), Occimum leaf powder (OLP), mahogany bark powder (MBP), hot pepper powder (HPP), ginger powder (GP) and mahogany wood ash (MWA) and a synthetic insecticide, pirimiphos-methyl dust (PMD) (0.1-0.5g/100g cowpea seeds) as...
