Comparision of Anti-Larvacidal Activity of Cassia occidentalis, Bamboosa vulgaris and Sapindus mukurossi

The present study evaluates the Anti-larvacidal of methanolic extract of Cassia occidentalis leaf, Bamboosa Vulgaris and Mukundus Saprossi at various concentrations against malarial vector. The various plant extracts exhibited larvacidal activity at different time intervals (24 hrs and 48 hrs). The mosquito larva of LC 50 and LC 90 values of Cassia occidentalis for I instar larvae 60.69%, 119.74%, the II instar 64.76%, 121.60%, III instar 67.78%, 123.35%, IV instar 70.56%, 122.81% and pupa 92.21%, 162.52% respectively.
