- The Asian longhorned tick (H. longicornis) was recently introduced in the U.S., and there is a lack of detailed surveillance data that affects understanding of its population and risk.
- A study conducted from May to August 2019 in Pennsylvania collected 615 samples, showing a mean density of H. longicornis at 9.2 per 100 m², which is higher than the native tick species Ixodes scapularis (8.5/100 m²).
- The tick's density was found to be significantly higher in August, particularly in recreational areas and Bucks County, providing important initial data for monitoring its distribution and potential risks.
