Author(s): Jadhav UB and Pardeshi AB
Abstract: The Callosobruchus chinensis L. is the most widespread and a dreadful pest of stored legumes. The conventional use of synthetic pesticide causes severe threats to life forms and not safe environmentally. Botanicals have broad range of spectrum as alternative to the synthetic pesticides. Therefore, the aim of this study was to evaluate the toxicity effect of aqueous, methanol and benzene leaves extract of Coleus amboinicus were studied against Callosobruchus chinensis. The plant leaves were dried, powdered and extracted with aqueous, methanol and benzene solvent in Soxhlet apparatus for 24 hrs. The 20 pulse beetles were exposed to various concentration (5.0 to 20 mg/ml) of aqueous, methanol and benzene plant extract of Coleus amboinicus and evaluated the toxicity after 96 hrs. The insecticidal activity of leaves extract of Coleus amboinicus were in aqueous (LC10 =16.6878, LC50 =20.0770 and LC90 =24.1546 mg/ml), in methanol (LC10 = 7.4920, LC50 =10.7176 and LC90 =15.3320 mg/ml) and in benzene (LC10 = 10.4592, LC50 = 13.6772 and LC90 = 17.8895 mg/ml) solvent respectively. The insecticidal activity of leaves extract of Coleus amboinicus were in aqueous (LC10 =16.6878, LC50 =20.0770 and LC90 =24.1546 mg/ml), in methanol (LC10 = 7.4920, LC50 =10.7176 and LC90 =15.3320 mg/ml) and in benzene (LC10 = 10.4592, LC50 = 13.6772 and LC90 = 17.8895 mg/ml) solvent respectively.
