Due to its vast diversity the Chagas vector, Triatoma dimidiata, has been merged and split into species and subspecies since its first description in 1811. Across its geographic range from Southern Mexico to Northern Peru populations differ in their biology and ethology in many ways including those that directly affect vector capacity and competence. Recent phenetic and genetic data suggest that T. dimidiata can be divided into at least three clades and in fact may be a polytypic species or species complex. To effectively target this vector, it will be necessary to clearly understand how "T. dimidiata" is genetically partitioned both at the taxonomic and population level.
由于其巨大的多样性，恰加斯病病媒——二色锥蝽自1811年首次被描述以来，经历了合并和划分为不同物种及亚种的过程。在其从墨西哥南部到秘鲁北部的地理分布范围内，不同种群在生物学和行为学方面存在诸多差异，包括那些直接影响病媒能力和传播力的方面。最近的表型和遗传数据表明，二色锥蝽可至少分为三个进化枝，实际上可能是一个多型种或物种复合体。为了有效针对这种病媒，有必要清楚了解“二色锥蝽”在分类学和种群水平上是如何进行基因划分的。
