Abstract

There are many natural/plant products, which can serve as an alternative to chemical pesticides. In this study efforts were made to find the optimal and effective dose of Neem and Karanj oil reportedly having pesticidal value against the cowpea beetle, Callosobruchus maculatus, on stored cowpea. The non-edible oils (Neem oil and Karanj oil) were evaluated for their efficacy in management of cowpea beetle. Treatments with different doses of Neem oil (0.10%, 0.25%, 0.5% and 1.0%) and Karanj oil (0.25%, 0.5%, 0.75% and 1.0%) were given. The data was recorded for % seeds with eggs laid, number of eggs per seed, perforations per seed, % damaged seeds as well as Weevil Perforation Index (WPI). The efficacy of the treatment has been worked out on the basis of adult emergence holes and WPI. Neem oil (0.5 and 1.0%) and Karanj oil (1.0%) provided absolute protection of stored seeds as these treatments did not show a single damaged seed. The percent germination in all treated seeds was also worked out. The results of this study suggested that the non-edible oils (Neem oil and Karanj oil) were found to be able to provide protection from seed weevil. So non-edible oils can be explored as an alternative to chemical insecticides against pulse beetle, Callosobruchus maculatus fab. in cowpea seed under storage.
