Abstract This study examines earthworm behaviour by combining locomotion-based motility assessments with evaluations of acetylcholinesterase (AChE) inhibition. Motility analysis revealed significant differences in the two-dimensional movement patterns earthworms exposed to carbamate pesticides compared those control group, indicating altered trajectories. AChE assays demonstrated a pronounced inhibitory effect on enzyme activity relative unexposed individuals. Both univariate and multivariate analyses confirmed that pesticide contaminant significantly affects as well quantitative directional characteristics movement. These results suggest behavioural testing is valuable tool for understanding impact non-target organisms environment.
