Multiple Introductions of the Asian Longhorned Tick (<i>Haemaphysalis longicornis</i>) to the United States Revealed Using Mitogenomics.

ABSTRACT: The Asian longhorned tick (ALT), Haemaphysalis longicornis, is a three-host hard tick native to East Asia. Its opportunistic feeding habits make it an acute agricultural and medical threat, capable of spreading various zoonotic pathogens. An affinity for livestock and companion animals has allowed parthenogenetic populations of ALT to travel to and establish in overseas locations including the United States. To better understand the population dynamics of this rapidly expanding species, we sequenced the complete mitogenome of specimens collected from native and invasive ranges and performed phylogeographic analyses. As well as illustrating the diversity of Australasian and US ALT haplotypes, these methods have allowed us to estimate the source and frequency of successful introductio
