Optimal Collection Methods for Asian Longhorned Ticks (Ixodida: Ixodidae) in the Northeast United States

Abstract The Asian longhorned tick, Haemaphysalis longicornis Neumann, is an invasive species in the United States. Since its earliest recorded presence West Virginia 2010, H. has been reported from 15 states. While public health significance States unclear, globally it transmits pathogens that infect livestock and humans, causing economic losses substantial morbidity. Management control of requires knowledge biology, ecology, distribution. Here, we address need for effective collection methods host-seeking as important step accurately assessing tick abundance potential disease risk. number collected were compared across three (dragging, sweeping, CO2 traps) check distances (5 m, 10 20 m) dragging sweeping. Field collections conducted June through August 2019 Westchester County, New York, ticks grouped by life stage to assess method efficiency. Results indicated implementing shorter distance was ideal adult nymphal collections. proved better than sweeping collections; however, there no significant difference between collections, at any evaluated. traps attracted longicornis, but additional research necessary devise retaining before can be implemented field. results are presented inform support surveillance programs nation.
