A botanical insecticide formulation containing seed extracts of Annona squamosa and Annona glabra belonging to Annonaceae has been developed to control four species of stored product insect pests, Callosobruchus chinensis (Coleoptera:Bruchidae), Oryzaephilus surinamensis (Celeoptera:Silvanidae), Sitophilus oryzae (Coleoptera:Curculionidae), and Tribolium castaneum(Coleoptera:Tenebrionidae). Botanical insecticide formulation was applied by topical application method at the dosage of 1, 5, 10, 20, 50, and 100 microgram/insect and residual effect method at the concentration of 0.01, 0.05, 0.08, 0.1, 0.2, and 0.4%. By topical application method, botanical insecticide formulation yielded more than 80% mortality of C. chinensis and O. surinamensis at 20 microgram/insect, while by residual effect method, the formulation yielded 80% mortality of C. chinensis and S. oryzae at 0.1%.
