Several biological parameters were evaluated to determine the capacity of Pimeliaphilus plumifer as biological control agent of Triatominae bugs. When P. plumifer and bugs of a variety of triatomine species were forced together in cages in the laboratory, the incidence of mite infestation was the following: Meccus pallidipennis > M. bassolsae > Triatoma rubida > M. longipennis > M. picturatus, and practically no mites were found on T. infestans and Rhodnius prolixus. Adults and hexapod larvae of P. plumifer were the only stages found to parasitize on M. pallidipennis. Fourth and fifth instar nymphs of this bug appeared most susceptible to mite infestation. P. plumifer mites located preferably on the coxae, ventral abdomen and pronotum of M. pallidipennis bugs. The number of blood meals, amount of ingested blood, and resistance to starvation of M. pallidipennis were similar in both the control and the mite infested groups. On the other hand, mite infection reduced molting rate in nymphs and longevity in adults, increased mortality in third-fifth instar nymphs, and fewer viable eggs were laid by females infected with P. plumifer. These effects could be related with nutritional deficiencies. Our results support the use of P. plumifer mites as control agents of host Triatominae species.
为了确定多毛嗜皮螨作为锥蝽生物防治剂的能力，对几个生物学参数进行了评估。当在实验室中将多毛嗜皮螨与多种锥蝽属昆虫放在笼子里强制放在一起时，螨感染的发生率如下：苍白麦蝽>巴萨尔麦蝽>红带锥蝽>长翅麦蝽>斑纹麦蝽，而在大劣按蚊和南美锥蝽身上几乎没有发现螨。多毛嗜皮螨的成虫和六足幼虫是唯一被发现寄生于苍白麦蝽的阶段。这种锥蝽的四龄和五龄若虫似乎最易受到螨的感染。多毛嗜皮螨主要位于苍白麦蝽的基节、腹面和前胸。在对照组和螨感染组中，苍白麦蝽的吸血次数、吸血量和耐饥饿能力相似。另一方面，螨感染降低了若虫的蜕皮率和成虫的寿命，增加了三至五龄若虫的死亡率，感染多毛嗜皮螨的雌虫产的 viable 卵较少。这些影响可能与营养缺乏有关。我们的结果支持将多毛嗜皮螨用作宿主锥蝽属物种的防治剂。 （注：“viable”此处可能有误，原文可能是“viable”，意为“可存活的”，推测可能是“viable”的拼写错误，暂按“viable”翻译）
