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 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 کاملارزیابی تاثیر دزهای اشعه گاما روی مراحل زیستی سوسک چهارنقطه‌‌ای حبوبات (Coleoptera: Bruchidae) Callosobruchus maculatus (F.)
سوسک چهار نقطه‌ای حبوبات، ازآفات مهم لوبیا چشم بلبلی در انبار می باشد. استفاده از روش‌های پرتودهی باعث کنترل پیوسته آفت، کاهش مسایل بهداشتی و زیست‌محیطی میشود. تاثیر دزهای مختلف پرتوگاما کبالت 60 روی مقدار ازت و درصد پروتیین، میزان خسارت و مراحل زیستی حشره آفت در شرایط آزمایشگاهی ارزیابی شد. نتایج نشان داد اشعه گاما بر درصد پروتیین و مقدار ازت لوبیا چشم‌بلبلی اثر منفی ندارد. در حالی که خس...
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 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...
