Abstract:

The insecticidal and repellent activities were observed by residual film method and surface film application methods respectively. Leaf, stem and root of Mimosa pudica L. were screened through Petroleum ether, chloroform, ethyl acetate and methanol extracts against flat grain beetle, Cryptolestes pusillus (Schon.). The plant extracts showed less to high mortality by using 0.25, 0.50, 1.0 and 2.0 mg/cm2 doses and the root extract showed most potency. In 72 h of exposure, chloroform extract of root showed the lowest LD50 value (2.024 mg/cm2) and 95% confidence limit was 1.730-2.292. In case of leaf, stem and root the highest mortality was recorded in chloroform extracts were 73.3, 70.0, 80.0%; 80.0, 76.7, 90.0% and 90.0, 86.7, 96.7% respectively in 24, 48 and 72 h. The repellency response among the three parts of the tested plant was different (p<0.05) and dose effect was more effective than exposure effect. The root extracts showed strong repellent activity than leaf and stem. The highest F-value was found 189.6542 and 83.48169 for dose and time effect respectively for petroleum ether extract of root. The order of dose-mortality effect of M. pudica extracts was root > leaf>stem and the susceptibility of contact toxicity in intensity of solvents was chloroform> petroleum ether > methanol > ethyl acetate. The order of intensity of repellent activity was root (petroleum ether) > leaf (petroleum ether) > stem (ethyl acetate).
