Juvenomimetic and larvicidal effects of Aloe vera and Bryophyllum pinnatum extracts against the larvae of confused flour beetles

Promising results obtained on the juvenomimetic and larvicidal effects of acetone extracts of two medicinal plants, Aloe Vera and Bryophyllum pinnatum on 6th instars larvae of confused flour beetle, Tribolium confusum indicated a great potential for its exploitation as insecticide. The development of larvae was completely inhibited at 1mg dose of Aloe vera leaf extract, as there was no emergence of adult at this dose. Larvae treated with extracts from Bryophyllum pinnatum did not complete their development also due to prolongation of larval period, formation of larvalpupal intermediates and abnormal pupae. Most of the adults emerging from such pupae showed deformed adults and died within a week after emergence without egg laying.
