| dc.description.abstract | Earthworms play important role in soil functions like soil aeration, stabilization of soil aggregates and water infiltration by their burrowing activity. The aforesaid activities are essential for maintaining the sustainability of agro ecosystem but they are decreasing and degraded because of indiscriminate use of pesticides. The earthworms ingest organically rich soil and release vermicast which harbour more bacteria than surrounding soil. This cast has buffering action for maintaining proper functioning of soil. The pesticide induces disruption in enzymatic activities and also affects the biomolecules composition of earthworms so present study was carried out to study the impact of pesticides toxicity on biomolecules compositions, immune cells and gut bacterial population of Pheretima posthuma. Both the pesticides viz. imidacloprid and pendimethalin were used individually as well as in combination for experimentation. Maximum reduction in biomolecule compositions was22.44%, 52.04% and 40.88% in crude protein, crude lipid, and carbohydrate respectively in earthworms treated with imidacloprid along with pendimethalin @ 0.60+2.50 μl/kg of substrate. There was significant reduction (72.28%) in coelomocytes, counted in earthworm exposed to highest concentration of imidacloprid along with pendimethalin @ 0.60+2.50μl/kg. Similarly, significant reduction was observed in number of granlocyte-I, granulocyte-II, mucocytes, lymphoidocytes and in vaculocytes. Maximum reduction inbacterial population inthe gut and vermicast was also observed in the same treatment. Among the two imidacloprid(insecticide) and pendimethalin (herbicide) imidacloprid was more toxic than pendimethalin when applied individually. | en_US |
