Effect of hydrogen peroxide and paraquat treatments on the 50% survival time, maximum survival time of the last fly and mean survival time of flies fed with control and diets containing 5 and 10 mg/ml CSE.

	50% survival (hour)	Maximum survival (hour)	Mean ± SD survival (hour)
Hydrogen peroxide challenge test
Control	7	16	9.31 ± 3.77
5 mg/ml CSE	8	16	9.79 ± 3.48
10 mg/ml CSE	10	24	12.53 ± 6.36**
Paraquat challenge test
Control	14	24	16.12 ± 2.69
5 mg/ml CSE	16	30	18.80 ± 6.22**
10 mg/ml CSE	17	32	20.07 ± 8.08**

**P < 0.01 when compared to control group.
