Abstract

Paederus fuscipes (Staphyilinidae) is comman in northen part of india particularly in Punjab and Haryana region. Most commonly found in maize, berseen and rice fields, also causes dermatitis in humans. It is a major polyphagous predator of several pests of agricultural importance. The leaf extract of Calotropis procera showed significant adverse effect on larvae and eggs at 1% and 5% concentration. The dry biomasses of different developmental stages treated with 5% aquous extract of C. procera revealed a significant reduction in growth rate of larvae, pupae and adults as compared to control. However, the negative growth rate was observed in pupae as they do not feed the treated diet. The phytochemical analysis of the extract revealed a wide range of secondary metabolites alkaloid, terpenoid, flavonoid, phenolic compounds and phytosterole. Thus, the present study was conducted to find out the insecticidal activity of C. procera for the control of the Paederus fuscipes.
