Effect of leaf extract of Azadirachta indica treated diet fed to adults of Spodoptera litura on fecundity and egg hatching

Abstract

The present investigation focus on Effect of leaf extract of Azadirachta indica treated diet fed to adults of Spodoptera litura on fecundity and egg hatching. Results show that when adult females of S. litura were fed on extract treated diet, drastic reduction in fecundity and egg hatching was observed. Maximum reduction in fecundity (68.93%) was observed when females were given A. indica seed extract treated honey solution as food. The effect was dose- dependent and increased with increasing concentration of extract. Egg hatching was adversely affected when adult females were fed on extract treated food. This indicate that ingestion of extracts with food by adults of S. litura have strong inhibitory effect on fecundity and also on egg hatching.
