The selected study area is located in Warangal rural district, Narsampet mandal of Telangana State. The study includes normal field where the maize, coriander& onions will be cropped and in these field the pesticides are not used and another one is pesticide treated field where cotton crop is cultivated. The study period is one year i.e. June 2015-May 2016. In this area most of the farmers are used monocrotophos, chlorpyrifos, imidacloprid, pesticides in their cotton fields. July, August and September months (South west monsoon) highest number of soil micro arthropods were recorded and in the months of November, December and January (North East monsoon) lowest number of soil micro arthropods were recorded. The highest number of soil micro arthropods in south west monsoon is due to less amount of pesticide usage and the lowest number in north east monsoon is high amount of pesticide application. There are Eight number of soil micro arthropods were identified belongs to two major groups these are Arachnida and Myriapoda. Among the two groups Arachnida group of micro arthropods were dominated. In this group especially Cryptostigmata, Mesostigmata and Prostigmata species were dominated. Pseudoscorpionida and Chilopoda were observed in lowest number.
