Global warming and biodiversity are always the matter of concern for the environmentalists and biologists. These issues have been raised on various platforms to aware masses. Vermicomposting is one of the important approaches towards its solution by using natural resources. Kota is situated in the south eastern part of Rajasthan state alongside Chambal River with very productive deep black/brown clayey soil. Maize, Wheat, Mustard and Soybean are the major crops of this region. In our research, it has been found that the main species of Earthworm in agricultural area around Kota city is Eisenia fetida. The main objective of this paper is to observe the effect of pesticides used for one Kharif season crop (Soybean). Triazophos and Pendimethalin are two popularly used insecticide and herbicide respectively for Soybean. For this, study has been conducted to observe the effect of Triazophos and Pendimethalin on avoidance behavior of Eisenia fetida in natural soil of Kota. Study of avoidance behavior of earthworm to pesticides is quick and easy to perform, and it is known to observe the sensitivity of earthworms towards a wide range of chemicals. Avoidance test has been performed by two compartment method in a container. This way optimal concentration of a specific pesticide may be determined so that farmers are encouraged to use these dosages and thus help to protect environment.
