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 کاملDeterrent Effects of Alstonia boonei Oil on Oviposition and Progeny Development of Callosobruchus maculatus (Fab.) [Coleoptera: Bruchidae].
BACKGROUND: Botanicals insecticides has remained the major weapons amongst tropical zones farmers to combat hexapods infestation of stored cowpea seeds in lieu of expensive synthetic chemical insecticides that have toxic effects on our environment. OBJECTIVES: Deterrence of cowpea bruchid oviposition and emergence on seeds treated with Cheese wood, Alstoni...
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 کاملEfficacy of plant extracts on the toxicity, ovipositional deterrence and damage assessment of the cowpea weevil, Callosobruchus maculatus (Coleoptera: Bruchidae)
A laboratory experiment was conducted to investigate the efficacy of different plant derivatives against the development of the cowpea weevil, Callosobruchus maculatus (F) (Coleoptera: Bruchidae) fed on cowpea, Vigna unguiculata (W) seeds. The leaf extracts of romatic plants, Murraya koenigii and Azadirachta indica (A.Juss) were evaluated for their growth, adult mortality and oviposition inhibi...
