Comparative Insecticidal Activities of some Botanical Powders and Pirimiphos-Methyl Against Callosobruchus maculatus Fab.[Coleoptera: Bruchidae] Infesting Cowpea Seeds
Cowpea, Vigna unguiculata [L.] Walp. is a widely planted nutritious grain legume [1]. It is cultivated in many West African countries including Nigeria. Cowpea is a source of dietary protein, vitamins and mineral salts. It has been consumed by human since the earliest practice of Agriculture in developing countries of Africa, Asia, and Latin America [2]. The pulse beetle, Callosobruchus maculat...
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 کاملControl of Cowpea Weevil, Callosobruchus Maculatus (F.) (Coleoptera: Bruchidae), Using Natural Plant Products
A laboratory study was conducted to investigate the effects of natural products on the reproduction and damage of Callosobruchus maculatus, the cowpea weevil, on cowpea seeds at Botswana College of Agriculture in Gaborone, Botswana. The cowpea variety Blackeye was used in the study. Fifty grams of each plant product (garlic, peppermint and chilies) was added to 500 g of the cowpea seeds. Findin...
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 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 ...
