Fig 5. Behavioral and physiological responses of E. heros after being sublethaly exposed to imidacloprid.

Walking activities (A) and respiration rates (B) of recently emerged (< 24 h) E. heros males and females sublethally exposed to imidacloprid. (C) Body masses of recently emerged E. heros males and females. Each histogram represents the mean (± SE) of 20 replicates. Vertical lines (A and B) and horizontal lines (C) indicate no differences according to a Tukey´ s HSD test (P < 0.05). Asterisks indicate significant differences between responses of imidacloprid-treated and untreated insects.
