Effect of Solvent Extracts of Pesticidal Plants for their Toxicity Against Aedes aegypti (L.)

摘要

Six plant's (Tridaxprocumbens Linn., fatropacurcas L., Annona squamosa L., Solatium xanthocarpum Schrad & WendL, Citrus limon (L.) Burm. and Menthaarvensis L.) were evaluated for their toxicity against Aedes aegyptii (L.) at different concentrations under laboratory conditions during 2013. The investigations resulted that S. xanthocarpum acetone extract exhibited higher level of larval mortality which registered the lower LC0 value (227.28 ppm) within the 148.95-346.80ppm (UCL and UCL) with the regression equation (Y = 2.2159x - 0.2206& R2=0.9357) followed by A squamosa and/, curcasvnth 350.18 and 445.12 ppm respectively. The minimum effect was registered by T. procumbens with the LC50 value of 905.81 ppm.
