Commonly Used Acaricides Found Effective on Invasive Tick
The Asian longhorned tick (Haemaphysalis longicornis), an invasive species in the U.S., is a threat to cattle and other livestock. A new study finds several pesticides used to manage other tick species are equally effective against the new arrival.
Interagency Cooperation Drives Discovery of Lyme Disease Spirochete in Exotic Tick
Analysis of Asian longhorned ticks collected in Pennsylvania found just one—out of more than 250 tested—carrying the bacteria that causes Lyme disease. The invasive tick is unlikely to play a role in Lyme transmission, but the research underscores the importance of active tick and pathogen surveillance and collaboration among agencies at local, state, and national levels.
Be On the Lookout: There’s a New Tick in Town
The Asian longhorned tick (Haemaphysalis longicornis) was discovered in the U.S. in 2017, and it poses health threats to both animals and humans. A new guide in the Journal of Integrated Pest Management outlines the different management strategies that are being developed, and surveillance and prevention are key to reducing this non-native arthropod's impact.
Lab Study Shows Asian Longhorned Tick Can Spread Rocky Mountain Spotted Fever
Researchers at the U.S. Centers for Disease Control and Prevention have found that the invasive Asian longhorned tick (Haemaphysalis longicornis) can, at least under lab conditions, acquire and transmit the bacteria that cause Rocky Mountain spotted fever.
