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.
寄生虫-宿主关系中被广泛接受的一个观点是，前者操纵后者，以增加自身的成功。在复杂的生命周期中，这意味着寄生虫能够操纵第一宿主，使其能够传播到第二宿主。在本文中，我将形式化地说明这种情况可能适用于克氏锥虫寄生虫及其载体——三锥虫亚科的臭虫。我讨论了现有证据的来源，并提出了一些类型的操纵。这种操纵也可能发生在第二宿主，即脊椎动物中。在这里，我强调人类和家养动物。我还讨论了全球变化和抗杀虫剂性如何推动三锥虫和克氏锥虫之间以及宿主操纵的军备竞赛。
