Abstract :

The study deals with evaluating insecticidal efficacy of a desert plant, Aerva tomentosa (family:Amaranthaceae), different parts of which were formulated using different extracts and at various concentrations against Tribolium castaneum. The results showed that the ether extracts at highest dose concentration of 10% were the most effective in increasing adult mortality, retarding rate of development, reducing egg laying, adult emergence and weight loss in host grains of Triticum vulgare. Among the plant parts the leaf was found to be most effective followed by fruit, root and stem
