22 November 2017 – We had to wait until an official joint press release was issued by the NJ Dept. of Agriculture and NJ Dept. of Health yesterday, but on November 9 Andrea, using the barcode mtDNA sequence, identified an unknown tick that had been found in Hunterdon county, NJ back in August. The tick was brought to our attention by Jim Occi, who was contacted by the Hunterdon Department of Health that shrewdly had figured out the tick was “something different”. Shortly after, Andrea’s tick ID was confirmed by USDA-APHIS. It is Haemaphysalis longicornis, the “longhorned tick” or “bush tick”. This species is native to northeast Asia (China, Russia, Japan) but expanded into Australasia (Australia, New Zealand, Pacific islands) in the 1800’s or early 1900’s. While H. longicornis had been intercepted several times in United States ports of entry, there are no known established populations in the New World. This tick is decidedly an agricultural (livestock) pest and disease vector and it has been associated with human pathogen transmission, particularly in farmers and those handling livestock. The question in everyone’s mind is: will it survive the NJ winter? That will likely depend on where it came from.
