ORGANOPHOSPHATES AND CARBAMATES AS INHIBITORS OF ACETYLCHOLINESTERASE IN EISENIA FETIDAJYOTI YADAV, DHARAMBIR SINGH, JAYANT YADAV AND DEEPAK KUMARAbstract Scientific literature addressing the impact of pesticides especially organophosphates and carbamates on the acetylcholinesterase commotion of earthworm is reviewed. Earthworms being the biotic indicators of soil health play an imperative role in refining soil fertility. To increase their number in agrarian ecosystems it becomes crucial to keep in mind their health too. With the upsurge in soil pollution due to heavy metals and pesticides, the numbers of earthworms as well as species are under the verge of riddance. So, it becomes obligatory to evaluate the mode of action of various pesticides on earthworm species. Organophosphates and carbamates are being extensively used in agriculture. These groups of pesticides mark their effect on earthworms by altering the neural transmission by targeting the acetylcholinesterase. Thus, acetylcholinesterase acts as biomarker for assessing earthworms health. Eisenia fetida, being more adaptable and tolerant towards the environmental fluctuations is the most utilized species for vermicomposting.
