Effect of solar drying on the biological parameters of the cowpea weevil, Callosobruchus maculatus Fab. (Coleoptera-Bruchinae), in Sahelian area
Objective: Callosobruchus maculatus Fab. (Coleoptera: Bruchinae) is a major pest of cowpea seeds (Vigna unguiculata (L.) Walp) in the Sahelian zone. The grain infestation by this insect pest starts in the field at the beginning of fructification of the plant and continues in storage where the damage can be significant if no protective measures are taken. In order to prevent the damage caused by...
متن کاملPotential of four tropical plant powders as grain protectants against Callosobruchus maculatus (Coleoptera: Chrysomelidae)
Effects of four tropical plant (Aframomum melegueta, Zanthoxylum zanthoxyloides, Piper guineense and Eugenia aromatica) were investigated under tropical laboratory storage conditions for the protection of cowpea seeds against insect infestation. The plant materials were pulverised into fine powder after air drying and admixed with 20 g of cowpea seeds at the ...
متن کاملEgg-Dumping Behavior Is Not Correlated With Wider Host Acceptance in the Seed Beetle Callosobruchus maculatus (Coleoptera: Chrysomelidae: Bruchinae)
If typical host plants are absent, some herbivorous insects “dump” eggs on unsuitable substrates, even though this can cause complete larval mortality and reduced maternal life span. In the seedbeetleCallosobruchusmaculatus (F.) (Coleoptera:Chrysomelidae: Bruchinae), the tendency to dump eggs varies genetically both within and between populations. A previous study hypothesized that egg-dumping ...
متن کاملInsecticidal activity of 2-tridecanone against the cowpea weevil Callosobruchus maculatus (Coleoptera: Bruchidae).
The effect of 2-tridecanone vapor on the cowpea weevil (Callosobruchus maculatus) development was determined. Seeds of cowpea were infested with adults and exposed to different doses of 2-tridecanone isolated from Pilocarpus microphyllus Stapf ex Holm, a plant species native from northeastern Brazil. The pure monoterpene was evaluated both undiluted as well as in the dilutions 1:10, 1:100 and 1...
متن کاملfumigant toxicity of essential oils extracted from three medicinal plants against callosobruchus maculatus adults (coleoptera: bruchidae)
fumigant toxicity of essential oils from foeniculum vulgare (apiaceae), teucrium polium (lamiaceae) and satureja hortensis (lamiaceae) were evaluated against the adults of cowpea seed beetle, callosobruchus maculatus exposed for 24h. essential oils were obtained through steam-distillation using a clevenger-type apparatus. bioassays were conducted at 28±2 °c and 60±5% r.h. in dark conditions. si...
