A New Hormone, Midgut Factor(s), That Links Diet, Neuroendocrine System and Reproduction in Phormia regina (Meigen)

昆虫和哺乳动物一样，用激素来调节自己的身体 功能协调发展的 在哺乳动物中，消化系统是一个主要来源， 荷尔蒙 越来越多的证据表明昆虫的消化系统 道也分泌大量的激素;拟议的研究 将专注于这些。 初步研究表明， 黑绿头苍蝇中肠的因子， 激活大脑神经分泌活动后， 吃足够的蛋白质餐。 大脑活动导致 完成卵子的发育。 这项研究将提供 昆虫激素的比较信息以及 哺乳动物消化道 它还可以提供信息， 未来的昆虫控制计划。

Insects, like mammals, use hormones to regulate their body functions. In mammals, the digestive system is a major source of hormones. Increasing evidence indicates that the insect digestive tract also secretes a large number of hormones; the proposed study will focus on these. Preliminary studies suggest that a hormonal factor from the midgut of the black blowfly, Phormia regina, activates brain neurosecretory activity after the female fly has taken a sufficient protein meal. The brain activity then leads to the completion of egg development. The proposed study will provide comparative information on hormones from insect as well as mammalian digestive tracts. It may also provide information for future insect control programs.//
