In the present study the ovicidal effect of leaf extracts and seed extract of Azadirachta indica was
evaluated against Spodoptera litura. The results show that the plants induced mortality in the eggs,
however the efficacy of plants varied. The ovicidal property of the leaf and seed extracts may be
attributed to the chemical compounds present in the plants. Results obtained in present investigation
show that seed extract of Azadirachta indica was most effective and caused highest mortality in
treated eggs. Results were obtained in the present work where 2 % seed extract of Azadirachta
indica caused 94.66 percent egg mortality. Leaf and seed extracts evaluated in the present study
caused mortality in the newly emerged larvae. Highest mortality within 48 hours of hatching was
observed in larvae emerged from eggs treated with leaf extract and seed extracts of Azadirachta
indica at the concentration of 2 %(83.82 and 100 percent respectively).
Key words: Azadirachta indica, leaf extract , seed extracts, Spodoptera litura.
