聚居在常绿矮秆竹叶鞘下的喜虫Macrope obnubilus被链翅目寄生虫Blissoxios esakii感染。为了确定昆虫-链翅目昆虫系统的生态特性，我们对大型寄生虫和异种寄生虫的自然种群进行了实地调查。链翅目成虫全年寄生率较高，雌性明显高于雄性，异种成虫主要在5月出现，新生成虫雌性在8月份释放三节幼虫。三鞭毛虫侵入寄主若虫，但随后的幼虫发育在幼虫成熟之前不会发生。由于空间限制，最多只能有两个链霉菌在一个寄主中成熟。三重或多重寄生虫的死亡率显著高于单寄生虫和双寄生虫，后者的存活时间比未感染的长。严重的链霉菌感染通过导致寄主繁殖失败而深刻地影响了寄主种群。
The blissine bugMacropes obnubilus, which lives aggregately under leaf sheaths of the evergreen dwarf bamboo, is infected by the strepsipteran parasiteBlissoxenos esakii. To determine the ecological properties of the bug–strepsipteran system, we conducted field surveys of natural populations ofMacropesbugs andBlissoxenosparasites. The parasitism rate of strepsipterans was high throughout the year and was significantly higher in female than in male bugs.Blissoxenosadult males emerged mainly in May, and neotenic adult females released triungulins in August. The triungulins invaded host nymphs, but subsequent larval development did not occur before the bugs matured. At most, two strepsipterans could mature in a host because of spatial limitations. The mortality of triply or more parasitized bugs was significantly higher than that of singly or doubly parasitized bugs, which survived longer than uninfected ones. The heavy strepsipteran infection profoundly affected the host population by causing host reproductive failure.
