A widely accepted idea in parasite-host relationships is that the former manipulates the latter so that it increases its own success. In the case of complex life cycles, this means that the parasite is able to manipulate the first host which allows its transmission to the second host. In this paper, I formalize the idea that this may be the case for the Trypanosoma cruzi parasite and its vectors, bugs of the subfamily Triatominae. I discuss the sources of existing evidence and propose some types of manipulation. This manipulation could also occur in the second host, that is, a vertebrate. Here, I emphasize humans and domesticated animals. I also discuss how global change and insecticide resistance may drive the arms race between both, triatomines and T. cruzi, and host manipulation.

在寄生虫-宿主关系中，一个广泛接受的想法是，前者操纵后者，从而增加自身的成功。在生命周期复杂的情况下，这意味着该寄生虫能够操纵第一宿主，从而使其传播到第二宿主。在本文中，我正式提出了一种想法，即克鲁氏锥虫寄生虫及其媒介，亚纲Triatominae的虫子可能就是这种情况。我讨论了现有证据的来源，并提出了一些类型的操纵方法。这种操纵也可能发生在第二个宿主，即脊椎动物中。在这里，我强调人类和家畜。我还讨论了全球变化和杀虫剂抗性可能如何推动三角藻素和克氏锥虫之间的军备竞赛以及宿主操纵。
