Genotoxicity evaluation of pesticide profenofos by applying dominant lethal test on Culex quinquefasciatus
Journal Title: Journal of Applied and Natural Science - Year 2011, Vol 3, Issue 2
Abstract
The present paper deals with the genotoxicity evaluation of profenofos by applying dominant lethal test (DLT) on Culex quinquefasciatus taken as an experimental model. For this, the males hatched from the larvae treated with LC 20 of pesticide were crossmated with normal females and the results were based on the number of hatched and unhatched eggs laid by these females. Mean percentage frequency of unhatched eggs was as low as 3.97 in the normal stocks as compared to treated stocks in which the frequency of unhatched eggs had increased to 9.50. The statistical analysis of the data from treated groups gave values of 9.50±1.35 as against 3.97± 0.38 in the control groups. Profenofos induced significant (p<0.05) dominant lethality.

Estimation of population mean in two– stage sampling under a deterministic response mechanism in the presence of non-response
In the present paper, we have considered the problem of estimation of population mean in the presence of non-response under two-stage sampling. Two different models of non-response with deterministic response mechanism h...
Study on mitigation of ammonia volatilization loss in urea through adsorbents
Volatilized ammonia loss (VAL) and toxicity are major disadvantages on urea amendment. In order to mitigate, slow (or) controlled release urea based fertilizers are prepared with low cost materials. Therefore, micro and...
