Toxicity of Neem Based Pesticides (Nimbecidine and Neemazal) On the Cotton Pest, Earias vittella
Journal Title: Scholars Academic Journal of Biosciences - Year 2014, Vol 2, Issue 11
Abstract
In the present study, the toxic effect of Nimbecidine and Neemazal on the cotton pest, Earias vittella was evaluated. For Neemazal T/S the doses used were 1.0, 1.5, 2.5 and 5.0 g/insect whereas for Nimbecidine 0.9, 1.1, 1.4 and 2.0 g/insect was used. A 24, 48, 72 and 96h toxicity test was performed to determine the LD (10, 50 and 90) values. It was found that toxicity was time as well as dose dependent. The result shows that the cotton pest, Earias vittella is very sensitive to Nimbecidine as compared to Neemazal. These pesticides are eco-friendly and gives outstanding results for the control of Earias vittella. Field experiments are suggested to elucidate the effects of these biopesticides on Earias vittella.
