对玻利维亚丘基萨卡西北部地区62只致病锥蝽的细胞色素B DNA部分序列进行了分析，以确定该昆虫种群的遗传变异程度。在采样地点共检测到7种单倍型。在这一地区发现的单倍型的系统发育关系和人口遗传结构，表明有更大的变化，在这个相对较小的地区的玻利维亚比以前报道的研究使用相同的基因片段，为更遥远的地理区域，这个国家。此外，通过比较农村和城郊地区的遗传变异，发现在中国北方地区的T.这两种环境之间的冲突。
Partial cytochrome b DNA sequences for 62 Triatoma infestans were analyzed to determine the degree of genetic variation present in populations of this insect in the northwest region of Chuquisaca, Bolivia. A total of seven haplotypes were detected in the localities sampled. The phylogenetic relationship and population genetic structure of the haplotypes found in this region, indicate that there is greater variation in this relatively small region of Bolivia than what has been previously reported by studies using the same gene fragment, for more distant geographic areas of this country. In addition, a comparison of rural and peri-urban localities, indicate that there is no difference in the genetic variation of T. infestans between these two environments.
