In this study, we used two different types of bioassay, a contact filter paper toxicity bioassay and a soil toxicity bioassay, to compare the acute toxicity of twenty-four insecticides belonging to six chemical categories on earthworm species, Eisenia fetida. Results of the contact filter paper toxicity bioassay indicated that neonicotinoids were super toxic to E. fetida (48 h-LC(50) value ranged from 0.0088 to 0.45 μg cm(-2)), pyrethroids were very toxic (48 h-LC(50) values ranged from 10.55… CONTINUE READING
