Effect of the two realistic indoxacarb concentrations on glutathione-S-transferase (GST) activity of Theba pisana after different time intervals of exposure

Days after exposure	GST activity (µmol/min/mg protein)
	Control	0.02 µg/mL		0.2 µg/mL
	Mean ± SE	Mean ± SE	% of control	Mean ± SE	% of control
7	0.385 ± 0.04a	0.392 ± 0.01a	101.81	0.435 ± 0.01b	112.98
14	0.728 ± 0.06a	0.802 ± 0.02ab	110.16	0.855 ± 0.04b	117.44
21	0.830 ± 0.07a	0.927 ± 0.08b	111.68	0.979 ± 0.09c	117.95
