Several of the pathophysiological responses made by the beetle Tenebrio molitor, when infected with metacestodes of Hymenolepis diminuta, may be attributed to a parasite-induced reduction in host juvenile hormone titre. It has been suggested that production of this hormone by the corpora allata may be inhibited in parasitized insects. This hypothesis was tested using an in vitro radiochemical assay to compare the biosynthesis of juvenile hormone by single pairs of corpora allata taken from mated 12- and 15-day-old infected and control female insects. The results demonstrate, however, that there was no difference in hormone production associated with metacestode infection. Other possible mechanisms for parasite interference in this host endocrine system are discussed.
当黄粉虫被微小膜壳绦虫的中绦期幼虫感染时，它所产生的几种病理生理反应可能归因于寄生虫诱导宿主保幼激素滴度降低。有人提出，在被寄生的昆虫中，咽侧体产生这种激素的过程可能受到抑制。本研究采用体外放射化学分析法，比较了从12日龄和15日龄已交配的感染和对照雌性昆虫中取出的单对咽侧体合成保幼激素的情况，对这一假说进行了验证。然而，结果表明，与中绦期幼虫感染相关的激素产生并无差异。本文还讨论了寄生虫干扰该宿主内分泌系统的其他可能机制。
