Abstract
Preliminary phytochemical studies have been carried out on 5 plant species, growing wildly in East Singhbhum,district of Jharkhand. The leaf extracts were prepared using organic solvent in soxlet apparatus. Three insect pests viz. storage pest, mealybugs and cut worm/caterpillar were used in the study. All the five plants studied exhibited pesticidal properties which are dose dependent. Annona squamosa and Cleistanthus collinus contains highest amount of the phytochemical and are most effective in these pest. It can be used as bio-pesticides. Blumea balsamifera was least effective as pesticides.
