Laboratory evaluation of some larvicidal agents against Anopheles culicifacies in Pune.

A laboratory study to evaluate some larvicidal agents against Anopheles culcifacies was carried out. The findings of this study brought out that the larvae of this species were highly susceptible to temephos, fenthion, Paris green and Mosquito Larvicidal Oil (MLO) in that order. The LC50 values in respect of these larvicides were 0.0009 ppm, 0.0081 ppm, 0.029 ppm and 0.015 ml respectively and LC90 values were 0.0018 ppm, 0.022 ppm, 0.11 ppm and 0.046 ml respectively.
