Efficacy of essential oil from Clausena anisata and its impact on biochemical changes of Sitophilus oryzae
Abstract
Essential oil (EO), from Clausena anisata, was evaluated for their efficacy (fumigant and repellent activities) against Sitophilus oryzae. Result revealed that C. anisata showed 82% fumigant toxicity (insect mortality) at 160 μL/L concentration after 24h observation period. C. anisata exhibited LC50 value of 17.84 μL/L concentration for fumigant toxicity. The insect movement behaviour (repellent) was observed in two different concentrations of 10 and 50 μL for a period of 3 h. Maximum repellent activity (- 0.25) was observed at 50 μL/L concentration against S. oryzae after 3-h observation. At 3, 6 and 12 μL/L concentrations of C. anisata oil significantly reduced the protein content and total esterase activity of S. oryzae.
