Average ( ± SE) HPG acinus diameter after 24 h, 48 h or 72 h of: (A) imidacloprid; or (B) coumaphos treatment. Sample sizes are n = 10 − 30; Same letters indicate that LSD tests (P < 0.05) established that HPG diameters after 24, 48 or 72 h exposed to imidacloprid or coumaphos were not significantly different.
