Evaluation of Bio efficacy of Azadirachta indica and Mentha piperita extract against Papilio demoleus L. on Citrus crop
Journal Title: International Journal of Biological Innovations - Year 2019, Vol 1, Issue 2
Abstract
Lemon butterfly (Papilio demoleus) is a serious pest of citrus crop. Present experiment was carried out in the laboratory under controlled conditions with three replications. Five concentrations of neem and mint extract were taken with solvent as petroleum ether, methanol, chloroform, and distilled water. The chloroform extract and methanol extract of Azadirachta indica and Mentha piperita were found to be effective with reduced larval survival up to 46.35%and 52.24%, respectively. With 20% neem extract concentration, survival percentage was found to be 47.8% and 46.3% in chloroform solvent after 24 and 72 hours of exposure, respectively. Methanol extract also revealed statistically at par results In control experiment, survival percentage was ranged from 97–100% in all solvent extracts. Similarly, with mint extract, survival percentage was found to be minimum with chloroform solvent (52.13%) followed by methanol solvent (58.08) after 24 hours. Similar trend was recorded after 48 and 72 hours of exposure.
