Botanical Pesticides for the Management of Callosobruchus chinensis Infesting Chickpea during Storage

Abstract

The present research on efficacy of botanicals against pulse beetle in stored chickpea was conducted under laboratory conditions at Department of Entomology, SHUATS, Prayagraj, India during 2020-2021. The experiment was carried in the Completely Randomized Design with twelve treatments (Neem oil, Castor oil, Pungam oil and plant powders neem leaf powder, neem seed kernel powder, Vasambu rhizome powder, Turmeric powder, Custard apple leaf powder, Eucalyptus leaf powder, Lantana camara leaf powder, Notchi leaf powder, insecticide (Rynaxypyr) and untreated control. The results were evaluated on the basis of adult mortality, weight loss and Feeding Detterent Index. Vasambu rhizome powder, Neem oil, Castor oil, and Pungam oil were discovered to be the most successful treatments, demonstrating 100% adult mortality, negligible weight loss, and 100% Feeding Detterent Index.The effectiveness of the plant oils is due to their repellency and ovipositional detterent effects on stored products and the effeciency of vasambu rhizome powder was due to the presence of active principle, keta osarone which induces premature death of insects.
