ABSTRACT

Excessive use of synthetic pesticide formulations has become an indispensable requirement in modern agricultural executions, to fulfill growing demands of food for continuously increasing human population. Consequently, the genotoxicity evaluation of corresponding xenobiotics has become crucial prerequisite, to assess their drastic and substantive effects on the integrity of genetic imprints of exposed organisms. The present investigation is attributed to the genotoxicity evaluation of ethion, employing hereditary material of Anopheles culicifacies exposed to sublethal aliquot, LC20 for continuation of 24 hours, implementing an in vivo approach viz: polytene chromosome aberration analysis. Exposure of concerned pesticide, ethion was given to second instar larvae, subsequently, larvae were reared upto fourth instar stage which were sacrificed for the study of salivary gland polytene chromosomes.
