Extracts of Lantana Camara Induced Toxicity and Acetylcholinesterase Inhibition Against Rice Pest Leptocorisa Oratorius.

Abstract

The present study aims to find the toxicity of different extracts of Lantana camara against the rice pest, Leptocorisa oratorius. It also intends to evaluate the acetylcholinesterase inhibitory property of the most active extract under study. Contact toxicity studies showed that 15% of the ethanol extract showed a high mortality rate of 92%, followed by methanol and aqueous extracts. Toxicity increased in a dose-dependent manner.Likewise, the plant ethanol extract causes 87.25% inhibition of acetylcholine esterase activity in insect physiology. It was determined that the L.camara plant extract has substantial insecticidal properties and acetylcholinesterase inhibitory effect against  L.oratorius.
