Acid DNase activity in the testes and fat body is high during the early larval instars which may be correlated with the extensive cell division seen in both the tissues during these stages. The increased enzyme activity, observed in the testes of the pupal stage, might be involved in the in vivo degradation of DNA in a large number of degenerating spermatocysts which occur during this stage. Total activity of acid DNase in the fat body is highest in pupal stage. Like acid phosphatase, this enzyme may also be involved in the process of remodelling of the fat body during metamorphosis. 20-Hydroxyecdysone (20-HE) does not have any effect on acid DNase activity in the testes but it alters the enzyme activity in the fat body. Juvenile hormone-I (JH-I) has no effect on the enzyme activity in the fat body.
在幼虫早期龄期，睾丸和脂肪体中的酸性脱氧核糖核酸酶活性较高，这可能与这两个组织在这些阶段出现的广泛细胞分裂有关。在蛹期睾丸中观察到的酶活性增加，可能参与了此阶段大量退化精囊肿中DNA的体内降解过程。脂肪体中酸性脱氧核糖核酸酶的总活性在蛹期最高。与酸性磷酸酶一样，这种酶也可能参与变态过程中脂肪体的重塑过程。20-羟基蜕皮激素（20-HE）对睾丸中的酸性脱氧核糖核酸酶活性没有任何影响，但它会改变脂肪体中的酶活性。保幼激素-I（JH-I）对脂肪体中的酶活性没有影响。
