在北美共有40种和亚种，分属于三栖动物属(Triatoma，Partriatoma，Panstrong ylus，Dipetalogaster，Belminus)的6个属。Rhodnius prolixus(以一种非本地种Rhodnius prolixus为代表，以前仅在国内栖息地发现)；28种，仅在墨西哥(和/或中美洲)发现，8种在美国(美国)和墨西哥共享，4种只在美国独有。其中，斑点藻属的种类最多，有26种，属于长尾类，包括长尾和网状复合体；红斑藻属，包括叶状复合体、叶状复合体和双体复合体。三叶虫物种丰富度在高纬度(美国南部)和低纬度(墨西哥特万特佩克Istmus以南)都有所下降。黑斑病主要分布在农田、草地、林地草地和林地景观中。土地覆被类型在马尾藻、长叶菊属和风信子复合体中最为相似，而在叶状体和分叶菊属复合体中则相反。对大多数物种的适宜性最高的土地覆被类型是林地草地，其次是丛生植物和双子叶植物物种复合体的林地，其余三个物种复合体的开阔灌丛和封育灌丛和农田。主成分分析被用来证明环境条件的潜在使用范围的差异：长期和叶状复合体占据最广泛的生态位。本研究以物种和物种复合体为基础，并基于预测的生态位，对潜在的三聚氰胺扩散区域进行了初步分层，这一方法已被证明具有非常重要的流行病学意义。(C)2008年，爱思唯尔出版。
In all, 40 native triatomine species and subspecies occur in NA, belonging to six genera from the Triatomini (Triatoma, Paratriatoma, Panstrongylus, Dipetalogaster, Belminus. Eratyrus), and one genus from the Rhodniini (represented by one non-native species Rhodnius prolixus, formerly occurring exclusively in domestic habitats); 28 species are found exclusively in Mexico (and/or Central America), eight are shared between the United States (US) and Mexico, and four occur exclusively in the US. The genus Triatoma is the most diverse with 26 species belonging to the species groups protracta, including the species complexes protracta and lecticularia, and rubrofasciata, which includes the species complexes rubida, phyllosoma and dimidiata. Triatomine species richness declined both at higher (south US) and lower (south of the Istmus of Tehuantepec, Mexico) latitudes. Triatoma species are found predominantly in cropland, grassland, wooded grassland and woodland landscapes. Land cover types were most similar among the lecticularia, protracta, and rubida complexes, in contrast to the phyllosoma and dimidiata species complexes. The land cover types having highest suitability for most species were wooded grassland, followed by woodland for the phyllosoma and dimidiata species complexes, and open and closed shrubland and cropland for the remaining three species complexes. A principal component analysis was used to demonstrate differences in the potential range for use of environmental conditions: protracta and phyllosoma complexes occupy the broadest niches. The present study represents a primary stratification of potential triatomine dispersal areas, based on species and species complexes, and based on predicted niche, a method which has already proven to be highly significant epidemiologically.
