病媒对宿主的利用对于了解人畜共患病的传播十分重要，人畜共患病可影响人类、野生动物和家畜。在这里，合成的主机开发模式的接吻错误，南美锥虫病的载体，提出。对于这种合成，进行了广泛的文献综述，仅限于通过沉淀素试验分析的饲养来源。从社区生态学和多元统计的现代工具被用来确定隔离主机使用的模式。接吻虫对宿主的使用不是天生的偏好，而是受到它们所殖民的栖息地的影响。关于吻虫觅食的研究的主要局限之一是只关注主要的病媒物种。我们建议，扩大觅食研究，考虑社区的载体将大大增加南美锥虫病传播生态的理解。我们的研究结果表明，主机的可访问性是一个主要因素，形状的血液觅食模式的接吻错误。因此，从应用的角度来看，旨在中断人类与接吻虫之间接触的措施，如住房改善，是控制恰加斯病最可取的战略之一。
Host use by vectors is important in understanding the transmission of zoonotic diseases, which can affect humans, wildlife and domestic animals. Here, a synthesis of host exploitation patterns by kissing-bugs, vectors of Chagas disease, is presented. For this synthesis, an extensive literature review restricted to feeding sources analysed by precipitin tests was conducted. Modern tools from community ecology and multivariate statistics were used to determine patterns of segregation in host use. Rather than innate preferences for host species, host use by kissing-bugs is influenced by the habitats they colonise. One of the major limitations of studies on kissing-bug foraging has been the exclusive focus on the dominant vector species. We propose that expanding foraging studies to consider the community of vectors will substantially increase the understanding of Chagas disease transmission ecology. Our results indicate that host accessibility is a major factor that shapes the blood-foraging patterns of kissing-bugs. Therefore, from an applied perspective, measures that are directed at disrupting the contact between humans and kissing-bugs, such as housing improvement, are among the most desirable strategies for Chagas disease control.
