The median and maximum life spans of Zaprionus paravittiger are 43 and 79 days, respectively, for males and 52 and 91 days for females at 24 +/- 2 degrees C. Sodium selenite (SS), an antioxidant, feeding prolongs the median as well as maximum life span of both the sexes. Antioxidative enzymes, catalase and peroxidase showed greater activity during the developmental stages. Females, at most of the age intervals, exhibited greater enzymatic activities as compared to their age-matched males. Both the sexes showed a statistically significant increase in the baseline activity of these enzymes as consequent upon SS feeding. It is suggested that SS acts by strengthening the antioxidative enzymes, namely catalase and peroxidase.
在24±2摄氏度条件下，副带蚤蝇雄性的平均寿命和最长寿命分别为43天和79天，雌性分别为52天和91天。喂食抗氧化剂亚硒酸钠（SS）可延长两性的平均寿命和最长寿命。抗氧化酶过氧化氢酶和过氧化物酶在发育阶段表现出更高的活性。在大多数年龄区间，雌性比同龄雄性表现出更高的酶活性。两性在喂食SS后，这些酶的基础活性均出现统计学上的显著增加。研究表明，SS通过增强抗氧化酶（即过氧化氢酶和过氧化物酶）发挥作用。
