Abstract

Haemaphysalis longicornis (Acari: Ixodidae), the Asian longhorned tick, is invasive in the United States. Originally from East Asia, this tick rapidly expands its range to include most of the habitats where it is introduced. From initial detection in New Jersey in 2017, H. longicornis has invaded over 18 states and 195 counties. The goal of this study was to determine if H. longicornis is established in Georgia, USA. Existing research into habitat suitability and reports of existing collections informed the selection of field sites for this study. Sites selected changed over both field seasons based on new data available from the USDA about H. longicornis in the USA. Over 10,000 ticks collected over 2 years were dichotomously identified, and then suspected samples of H. longicornis received molecular confirmation. The 2022 field season involved collecting ticks from 42 State parks and wildlife management areas throughout Georgia. From all sites surveyed, we collected 3 H. longicornis nymphs in Buck Shoals wildlife management area in White County, Georgia. This is the first collection of H. longicornis on public land. This difference in habitat indicates that the general habitat in Georgia could be suitable for H. longicornis establishment. Further research will occur at this location and the locations previously identified as suitable to understand the establishment of this species within Georgia.
