studies on larvicidal activity of plant essential oil formulation against the eggs of important vector mosquitoes, anopheles stephensi (liston), culex quinquefasciatus (say) and aedes aegypti (l.) at laboratory condition

In the present investigation Plant Oil Formulation (POF) with different concentrations were tested for its larvicidal activity against the eggs of Anopheles stephensi (Liston), Culex quinquefasciatus (Say) and Aedes aegypti (L.). Results clearly indicated that among the five concentrations tested (15.62, 31.25, 62.5, 125 and 250 ppm) maximum cumulative mortality of eggs were obtained at 250 ppm concentration of POF against the fourth instar larvae of the selected species. The present investigation paves the way for further exploration of possible way of utilizing the POF in IPM to control the important vector mosquitoes.
