For chlorpyrifos treated group, data represents mean ± SEM. ** p < 0.01 control vs 5% (8.4 ng/cm²) and 10% (16.8 ng/cm².) of LC₅₀. For cypermethrin exposed group, data represents mean ± SEM. * p < 0.05 control vs 5% (1.0 ng/cm²) and 10% (2.0 ng/cm²) of LC₅₀, ** p < 0.01 control vs 5% and 10% of LC₅₀ and for the earthworms exposed to combination of pesticide, data represents mean ± SEM * p < 0.05 control vs 5% and 10% of LC₅₀, ** p < 0.01 control vs 5% (3.3 ng/cm²) and 10% (6.6 ng/cm²) of LC₅₀. Here, PC: Pre-clitellar, C: Clitellar and PtC: Post- clitellar regions of earthworm.
