Abstract
Preliminary studies using the leaf extracts of Azadiraehta indioa A, Juss (Melia azadirachta L., Melia indiea, neem or nim tree) collected in Mombasa, Kenya, showed that when the crude extract was applied to coffee leaves, its potency in causing morphological changes in Antestiopsis (coffee bug) was stronger than that of an equivalent weight of β-ecdysone (insect molting” hormone). It was during attempts to isolate the active compound that we encountered azadirachtin.
