Suspect archival specimens that were available among previously collected ticks were also examined. Through these efforts, enhanced vector and animal surveillance were implemented to detect additional tick infestations. The USDA Animal and Plant Inspection Service coordinated cooperative efforts through telephone conference calls with various local, state, and federal agricultural and public health agencies. Department of Agriculture, personal communication). ports of entry at least 15 times on imported animals and materials (James W. longicornis ticks were intercepted at U.S. In some regions of New Zealand and Australia, this tick can reduce production in dairy cattle by 25% ( 6). In addition, parthenogenetic reproduction, a biologic characteristic of this species, allows a single introduced female tick to generate progeny without mating, thus resulting in massive host infestations. Studies in Asia identified ticks infected with various species of Anaplasma, Babesia, Borrelia, Ehrlichia, and Rickettsia, and all of these pathogen groups circulate zoonotically in the United States ( 4, 5). In China and Japan, it transmits the severe fever with thrombocytopenia syndrome virus (SFTSV), which causes a human hemorrhagic fever ( 2), and Rickettsia japonica, which causes Japanese spotted fever ( 3). Where this tick exists, it is an important vector of human and animal disease agents. It is an introduced, and now established, exotic species in Australia, New Zealand, and several island nations in the western Pacific Region. longicornis is native to eastern China, Japan, the Russian Far East, and Korea. longicornis to serve as a vector for a range of potential pathogens, and evaluation of effective agents and methods for the control of H. longicornis currently harbors, determination of the capacity of H. longicornis, detection of pathogens that H. To forestall adverse consequences in humans, pets, livestock, and wildlife, several critical actions are indicated, including expanded surveillance to determine the evolving distribution of H. The hosts included six species of domestic animals, six species of wildlife, and humans. In the spring of 2018, the tick was again detected at the index site, and later, in other counties in New Jersey, in seven other states in the eastern United States, and in Arkansas. This was the first detection in the United States outside of quarantine. longicornis was discovered on a sheep in New Jersey in August 2017 ( 1). Haemaphysalis longicornis is a tick indigenous to eastern Asia and an important vector of human and animal disease agents, resulting in such outcomes as human hemorrhagic fever and reduction of production in dairy cattle by 25%.
