Bioefficacy of Biophytum sensitivum (L.) leaf extracts against Dengue Mosquito Vector Aedes Aegypti (L.)
2012
Novel bioactive molecules of plant origin are very important for success of vector control programs. In the present study the larvicidal activity of Biophytum sensitivum leaf extracts were analysed on Aedes aegypti mosquito. Concentrations of 10, 15, and 25 mg/L of extract were used to determine larvicidal, pupicidal and consequent effect on adult emergence. Results show that acetone extract had a dose-dependent effect and produced higher mortality (LC50 = 21.79 and LC99 = 139.50 µg ml -1 ) in larvae. Pupicidal activities of acetone extract showing (LC50 = 13.05 and LC99 = 137.75 µg ml -1 ) the highest effect. Acetone extracts also delayed the normal
