Chromosomal studies were carried on six larval populations of Simulium (Chirostilbia) pertinax from different locations in Brazil. Larvae were collected in the states of Paraná, Rio Grande do Sul, Rio de Janeiro and São Paulo. Polytene chromosome map comparisons within and among populations showed no differences in banding pattern, except for some limited polymorphism (secondary NOR and four band polymorphisms). There were no chromosomal variations associated with the resistance or susceptibility of the larvae to temephos. The chromosomal homosequentiality found among the six populations suggests that S. pertinax may be a monomorphic species.
对来自巴西不同地点的六个 Pertinax 蚋（Chirostilbia 亚属）幼虫种群进行了染色体研究。幼虫采集于巴拉那州、南里奥格兰德州、里约热内卢州和圣保罗州。种群内部和种群之间的多线染色体图谱比较显示，除了一些有限的多态性（次缢痕和四个带型多态性）外，带型模式没有差异。幼虫对特丁磷的抗性或敏感性与染色体变异无关。在这六个种群中发现的染色体同序列性表明，Pertinax 蚋可能是一个单态物种。
