Abstract: 
Water extracts, methanolic extracts and the petrol ether phase from the fruit and leaves of Melia azedarach L. were tested against different instar nymphs of Locusta migratoria migratorioides (R. & F.) under laboratory conditions. Water extracts caused various degrees of mortality and a significant delay in the development and growth of the locusts. Treatments with 3% concn of water extracts from the fruit and leaves at a rate of 40 ml/m2 gave 93% and 100% mortalities, respectively, of first instars, and a 3% concn of leaf extract resulted in a mortality of 93.2% of third instars. Antifeedant and/or stomach-poison effect(s) played an important role. MeOH extracts had the same efficacy as water extracts, but the petrol ether phase did not show much effect on the locusts.
