The effects of the infection caused by the microsporidium Polydispyrenia simulii in gonads of the simuliid Simulium pertinax were evaluated. This blackfly species is the main target of control programmes in southeastern Brazil. Infected and noninfected blackflies were reared from larval stage to adults using a laboratory rearing system. There was no significant difference between the oogenic development and dimensions of ovarian follicles of healthy females compared to those reared from infected larvae. Otherwise, there was a significant difference between the fecundity of healthy females and those reared from infected larvae. In males, there was an evident reduction of motility of spermatozoids of males reared from infected larvae. The results obtained suggest that the microsporidium P. simulii have an important effect on the natural population dynamics of S. pertinax.
评估了微孢子虫多散核虫（Polydispyrenia simulii）感染蚋科昆虫佩氏蚋（Simulium pertinax）性腺所产生的影响。这种蚋类是巴西东南部控制项目的主要目标。使用实验室饲养系统将受感染和未受感染的蚋从幼虫阶段饲养至成虫。与从受感染幼虫饲养的雌性相比，健康雌性的卵子发生发育和卵巢卵泡大小没有显著差异。否则，健康雌性和从受感染幼虫饲养的雌性在繁殖力上存在显著差异。在雄性中，从受感染幼虫饲养的雄性精子活力明显降低。所得结果表明，微孢子虫多散核虫对佩氏蚋的自然种群动态有重要影响。
