Abstract
Helicoverpa armigera
larvae in their third instar were utilized to test the larvicidal activity of
ethanolic as well as aqueous extracts of Argemone Mexicana leaves at
several concentrations (5, 10, 15, 20, & 25mg/ml). Leaves of plant had been
dried, ground into a powder, and then extracted over course of a day in an
ethanol and aqueous solvent employing a Soxhlet system. Third-instar H.
armigera larvae have been exposed to varying concentrations, and after
96hours, mortality rate was noted. In ethanol, larvicidal activity of A.
mexicana leaf extract had been LD10=7.65mg/ml, LD50=20.54mg/ml, while in
water, it was LD10=10.17mg/ml, LD50=31.55mg/ml. Findings demonstrated that
mortality rose as plant extract content rose. Greater larvicidal effects
against H. armigera larvae in their third instar were demonstrated by
ethanolic solvent extract of A. mexicana. Regression equations, variance
statistics, along with 95 percent confidence limits have been displayed.
