Abstract Abstract: Earthworms play a crucial role in soil ecosystems, particularly agroecosystems, where they are both abundant and indispensable. Their activities enhance soil health by boosting nutrient availability, improving drainage, and fostering a more resilient soil structure all of which contribute to greater agricultural productivity. Often referred to as 'ecosystem engineers,' earthworms profoundly influence the soil's physical, chemical, and biological properties, shaping its overall profile. These changes can impact the habitat and behaviours of other organisms within the soil ecosystem. Earthworms also serve as bioindicators, playing a vital role in monitoring and assessing the health of natural ecosystems in their environment (Wang et al., 2015a, Ye et al., 2016). Soil pollution has become a growing environmental issue in agricultural regions worldwide, largely due to the extensive use of pesticides. Cyantraniliprole 7.3% w/w combined with Diafenthiuron 36.4% w/w SC is a recently introduced systemic insecticide, extensively employed to manage chewing and sucking insect pests. When sprayed on plants, these compounds are absorbed and transported within the plant, rendering parts or the entire plant toxic to insects that consume its tissue. To fully understand the ecological effects, it is crucial to conduct comprehensive studies on the application of this combined product. To assess the toxic impact of Cyantraniliprole 7.3% w/w + Diafenthiuron 36.4% w/w SC on earthworms, acute study was conducted with different concentrations viz.,10, 50,100, 250, 500, 750 and 1000 mg/ kg dry artificial soil. Mortality and Sublethal observation were done on Day 7 and Day14. No mortality was found up to 1000 mg/ kg dry artificial soil on Day 7 and Day14 but there was reduction was observed in body weight. The data was analysed using IBM SPSS Statistics Version 29. The data was normally distributed and homogeneously present. Hence, for Biomass parametric One-way ANOVA Dunnett t (2-sided) test was performed. Further research will be done to assess the toxic impact of test item on earthworms, the levels of reactive oxygen species (ROS) (Mittler, 2002); and malondialdehyde (MDA), activities of superoxide dismutase (SOD), catalase (CAT) and glutathione S-transferase (GST), Acetylcholinesterase (AChE) enzyme activity as well as DNA damage will be measured.
