The effect of an experimentally increased octopamine content (feeding flies with OA) on the levels of juvenile hormone (JH) degradation, dopamine (DA), and 20-hydroxyecdysone (20E) contents, oogenesis, and fecundity of wild type Drosophila flies has been studied. OA feeding of the flies was found to (1) cause a considerable decrease in JH degradation in females, but not males, of D. melanogaster and D. virilis; (2) have no effect on DA content in D. melanogaster and D. virilis; (3) increase 20E contents in D. virilis females; (4) decrease to a large extent the number of vitellogenic (stages 8-10) and mature (stage 14) oocytes in D. virilis; and (5) decrease the fecundity of D. melanogaster and D. virilis. A possible mechanism of action of OA as a neurohormone on the reproductive function of Drosophila is discussed.
研究了实验性增加章鱼胺含量（用章鱼胺喂养果蝇）对野生型果蝇幼体激素（JH）降解水平、多巴胺（DA）、20-羟基蜕皮酮（20E）含量、卵子发生及繁殖力的影响。结果发现，用章鱼胺喂养果蝇会：（1）导致黑腹果蝇和粗壮果蝇雌性（而非雄性）的JH降解显著降低；（2）对黑腹果蝇和粗壮果蝇的DA含量无影响；（3）增加粗壮果蝇雌性的20E含量；（4）大幅减少粗壮果蝇中卵黄生成期（8-10期）和成熟期（14期）卵母细胞的数量；（5）降低黑腹果蝇和粗壮果蝇的繁殖力。文中讨论了章鱼胺作为神经激素对果蝇生殖功能的可能作用机制。
