本文报告了１７一α一甲基睾丸酮和１７β一雌二醇两种类固醇激素对中国对虾幼体蜕皮和生长的影响。通过投喂含有激素的饵料进行实验，结果表明：与对照组比较，１５天实验中，１７α一甲基睾丸酮和１７β一雌二醇实验组幼体分别提前２天和１天全部进入仔虾期；１６天实验中，后１０天（第７天到第１６天）１７α一甲基睾丸酮实验组幼体生长明显加快（Ｐ＜．０５），１７β一雌二醇实验组幼体生长无显著变化（Ｐ＞０．０５）。
This article reports the effects of 17-α-methyltestosterone and 17β-estradiol on the molting and growth of juvenile P. chinensis. The results showed that compared with the control group, the larvae of 17α-methyltestosterone and 17β-estradiol experimental groups all entered the larvae stage two days and one day earlier than the control group respectively. In the 16-day experiment, the larval growth of 17α-methyltestosterone group was significantly accelerated in the last 10 days (day 7 to day 16) (P <.05), and there was no significant change in larval growth of 17β-estradiol experimental group (P> 0.05).
