保幼激素调节蜜蜂的变态、繁殖和行为发育,由幼虫和成蜂食道两侧的两个球形器官咽侧体合成。咽侧体和其他两个内分泌器官由神经相连,脑部通过神经内分泌信号调节咽侧体的活性。体外实验中,血液里的保幼激素滴度与咽侧体的合成速率相关,说明循环的保幼激素的数量主要由合成速率决定。保幼激素和蜕皮激素一起控制幼虫和蛹的成长和
Juvenile hormones regulate bee metamorphosis, reproduction and behavior development, by the larvae and into the bees on both sides of the two spherical organ pharynx side body synthesis. The pharyngeal side and the other two endocrine organs are connected by nerves, and the brain regulates the activity of the pharyngeal side through neuroendocrine signals. In vitro experiments, the juvenile hormone titers in the blood correlate with the rate of synthesis of the pharyngeal body, indicating that the amount of circulating juvenile hormone is mainly determined by the rate of synthesis. Juvenile hormones and ecdysteroids control the growth of larvae and pupae
