Corpora allata of Locusta migratoria 5th stage larvae synthesize J.H.1, J.H.2 and J.H.3 in vitro. The C.A. of insects of different ages exbit different rates of J.H. synthesis. J.H.1 and J.H.2 synthesis is less than 1 ng/48 h/gland. During the same time the J.H.3 production may be as much as 25.6 ng/gland. J.H. synthetic activity is the same between right and left C.A. The release of J.H. from the C.A. occurs immediately following synthesis. These results are compared with in vivo haemolymphatic J.H. levels.
飞蝗五龄幼虫的咽侧体在体外合成保幼激素1（J.H.1）、保幼激素2（J.H.2）和保幼激素3（J.H.3）。不同年龄昆虫的咽侧体表现出不同的保幼激素合成速率。J.H.1和J.H.2的合成量小于1纳克/48小时/腺体。在同一时期，J.H.3的产量可能高达25.6纳克/腺体。左右咽侧体之间的保幼激素合成活性相同。保幼激素从咽侧体的释放紧跟在合成之后。这些结果与体内血淋巴中的保幼激素水平进行了比较。
