Effect of Chlorpyrifos on Morphological Phenomenon of Earth Worm Lampito Mauritii (Kinberg)

Abstract

The study aimed to assess the toxicological effects of  organophospate pesticide chlorpyrifos on Lampito mauritii(Kinberg) .The lethal concentrations (LC50 ) were measured experimentally by exposing the earthworms in artificial soil test. The  study revealed that chlorpyrifos was found to be the most hazardous insecticide at a 48-hour period, with a LC50 value of  severe toxic 1to 10μgcm-2  against the earthworms. Few morphological  signs like  curling and mucus secretion bulging of clitellum were observed.
