AbstractBotanical pesticides are used in a variety of pest control situations. Their less-toxic nature
makes them a suitable candidate for IPM. They possess dose-dependentanti-insect
activities starting from repellency and leading to the death of insects. Their large-scale
utilization is obstructed by the non-availability of formulations. A potential botanical
Thevetia peruviana (Pers).K.schum,whose influence on various physiological systems of
Spodoptera litura was studied.Acetone fraction of hexane extract, acetone fraction of
methanol extract, and acetone fraction of ethyl acetate extract were found to possess
insecticidal activity. Among them,acetone fraction of hexane extract was the most
promising extract with LC50 of 5 percent. At LC50, the carbohydrate, protein, and lipid
contents were reduced to the tune of 80, 63, and 73 percent.
