Abstract:

The present study was carried out for comparative assessment of imidacloprid and pendimethalin on the bacterial population of gut and cast of Pheretima posthuma. The samples of gut and cast from earthworm treated for 90 days were cultured on five different culture media viz. King’s B media, YEMA media, Malate media, Jensen's media and Nutrient agar.Dose dependent decrease in bacterial population was observed in the entire population of treated earthworm’s gut and their cast in comparison to control. Maximum reduction in bacterial colonies of gut and cast were 53.13% and 58.53 %for Rhizobium(YEMA media)whereas minimum reduction15.52% and 24.89%for total viable bacterial colonies(Nutrient agar media) in earthworm’s gut and its cast respectively when the wormswere exposed to combined dose of imidacloprid and pendimethalin@0.60+ 2.50 µl/kg of substrate. Results revealed that combined doses of these pesticides were more harmful than individual doses and among the two pesticides; imidacloprid was more harmful than pendimethalin.
