The defensive glands of beetles, Tenebrio molitor, infected with metacestodes (cysticercoids) of Hymenolepis diminuta are everted less frequently upon stimulation, and contain less toluquinone (methylbenzoquinone) and m-cresol, than glands of uninfected controls. These differences, as shown in predation trials with wild rats, increase the likelihood that both cysticercoids and beetles will be ingested by the tapeworm's definitive host. This is the first documented case of a parasite inhibiting the chemical defence of an intermediate host, and one of only a few reports of parasite-induced manipulation of host biology supported by empirical evidence implicating facilitated parasite transmission between host species.
感染了微小膜壳绦虫的成虫期幼虫（似囊尾蚴）的黄粉虫的防御腺，在受到刺激时外翻的频率较低，并且与未感染的对照虫体的腺体相比，所含的甲苯醌（甲基苯醌）和间甲酚更少。如在对野生大鼠进行的捕食试验中所示，这些差异增加了似囊尾蚴和黄粉虫被绦虫终末宿主摄入的可能性。这是有记录的第一例寄生虫抑制中间宿主化学防御的案例，也是少数几例有经验证据支持的寄生虫诱导宿主生物学改变从而促进寄生虫在宿主物种间传播的报告之一。
