Effect of leaf and seed extract of custard apple (Annona squamosa L.) on ovicidal activity against Spodoptera litura F.

Panditrao Shiragave

Abstract

The ovicidal activity of Annona squamosa L. leaves and seed extracts with organic solvents 0.1-1.0% acetone and ethanol respectively were evaluated against Spodoptera litura under laboratory conditions. An experiment was conducted to find out ovicidal activity of leaf and seed extracts of Annona squamosa against eggs of S.litura. The highest ovicidal activity was found in 1% ethanol seed extract (72±0.1)) and leaf extract (52±1.0) at 96 hours after treatment. Acetone leaf and seed extract exhibited low percentage of ovicidal activity in Spodoptera litura.
