Studies on the Insecticidal Activity of LeucasAspera against the Rice Weevil, Sitophilus Oryzae
Abstract: The present study was aimed to analyze the insecticidal activity of extracts of Leucas aspera on (Rice weevil) Sitophilus oryzae. On analysis, a concentration of 250 mg/ml of the plant extract showed highest mortality. Certain secondary metabolites present in plant such as alkaloids, phenolic compounds and saponins were found to be responsible for the toxic effect, contributing inhibitory activity. A remarkable inhibitory effect was observed on the activity of Acetyl Choline esterase and Glutathione S transferase in the insect.
Keywords: Leucas aspera, Acetyl Choline esterase, Glutathione S transferase, insecticidal activity
