| Aporrectodea caliginosa | Chlorpyrifos and azinophos-methyl | ChE | Inhibition of cholinesterase (ChE) | [14] |
| Eisenia andrei | Carbaryl | ChE | Inhibition of ChE observed even at lowest dose | [68] |
| Aporrectodea caliginosa | Chlorpyrifos and Diazinon | ChE | In juvenile, ChE activity was inhibited when exposed to 12 (75% inhibition) and 60 (90%) mg/kg of Diazinon. ChE depression of 35% and 70% was observed w. r. t. control when exposed to 4 and 28 mg/kg, respectively | [69] |
| Eisenia fetida | Monocrotophos | AChE | AChE inhibition was observed Dose-dependent. AChE activity co-related with morphological damage | [70] |
| Eisenia andrei | Carbaryl | AChE | Dose-dependent AChE activity was observed | [71] |
| Drawida willsi | Butachlor, Malathion and Carbofuran | AChE | When exposed to butachlor, no variation of AChE activity; on malathion exposure, maximum AChE inhibition (41% and 46%) after 9d and after 12d (54% and 62.9%) of carbofuran exposure | [72] |
| Pheretima peguana | Chlorpyrifos | AChE | AChE acitivity is significantly inhibited (>60%) at two concentrations of pesticide | [73] |

| Eisenia fetida | Carbofuran | TChE | Protein content and total cholinesterase activity increased in low level and vice-versa | [75] |
| Eisenia fetida | Atrazine and chlorotoluron | SOD | Chlorotoluron is less toxic to atrazine. Synergistic effect observed when combined.SOD activity is enhanced. | [76] |
| Eisenia fetida | Carbofuran | SOD | When pesticide concentration is increased, SOD is reduced and vice-versa | [75] |
| Eisenia fetida | Chlorpyrifos and fenvalerate | SOD, Cellulase and CAT | Inhibition of SOD and cellulase whereas CAT activity increased first and then decreased. | [77] |
