Abstract
The toxicity of various extracts of Lantana camara L. leaves was investigated against Cadra cautella (Walker) eggs, larvae and adults. For eggs and larvae film residue method and for adults specimen tube method was followed, then it was compared with azadirachtin technical (20 %). The toxicity of various extracts on egg, larval and adult mortality was compared. The egg mortality was based on their hatchability. It was observed that through film residue, most of the extracts of L. camara showed higher mortality as compared to azadirachtin. Based on LC50 values methanol fraction of hexane extract (LC-3) and hexane extract of hexane fraction (LC-4) of L. camara were found to be most effective against different stages of C. cautella. The mortality was dose dependent and it increased with increasing concentration. The leaf extracts of L. camara were positively toxic to insects. The effects of various extracts on different stages of C. cautella are discussed.
