Melia azedarach L., a deciduous tree of moderate size, grown throughout warm countries, possesses various uses in our day-to-day life. The extract of plant parts (leaves, fruits or root bark) in different solvent systems (methanol, benzene, hexane, acetone) when applied to insect-pests of field plantation crops, acts as phagorepellent, ovipositional deterrent and antifeedant and also causes morphogenetic defects. In this review, the work done by different workers on insecticidal properties of the tree has been described and discussed alongwith the LC50 \AFC50 \LC95 of extracts from different parts of the plant against the different pests of agricultural importance.
