Geographic ranges of ticks and tick-borne pathogens within North America are shifting due to environmental changes and human-driven activities, with species of public health concern presenting a multifaceted risk to human health. Innovative strategies and continued collaboration to control tick populations are needed to combat this growing threat. We conducted a scoping review of the literature to describe the nature of applied tick control research conducted in North America (Canada, Mexico, and the United States) to date, with the goal of describing key concepts and identifying gaps in this research area.

Ixodid ticks serve as hosts and transmission vectors for several obligate intracellular bacteria, including members of the spotted fever group (SFG) of . Although ticks generate an immune response to bacterial insults, many of the signaling molecules associated with the response and how they may contribute to vector competence for are undefined. In this study, we isolated a full-length transcript from , which encoded a Relish-type NF-κB.

Diatomaceous earth (DE) recently was shown to rapidly kill ticks. Proof of concept for use of DE to kill the American dog tick, Dermacentor variabilis, the most widely distributed native three-host tick in North America, has not been investigated. Unfed D.
View Article and Find Full Text PDFOff-host periods are critical for ticks, representing a period when environmental stress, particularly dehydration, can impact tick survival. To prevent dehydration, ticks must be able to detect and move into high humidity areas to allow for water vapor uptake. Ionotropic receptor 93a (Ir93a), which is highly expressed in the front forelegs (location of Haller s organ), increases expression following dehydration, suggesting a role in humidity detection.

Article Synopsis
- Anaplasma bovis is a disease-causing agent primarily affecting ruminants and has been mostly found in Asia, the Middle East, and Africa; rare human infections have been reported, mainly due to Anaplasma phagocytophilum.
- A study aimed to check the prevalence of an A. bovis-like agent in the Southcentral U.S. found it in 3.1% of ticks from Oklahoma, but no presence was detected in cattle blood.
- The results suggest that the A. bovis-like agent is likely present in the U.S. and could be a potential zoonotic threat, highlighting the need for further research to identify its reservoirs and assess the human infection
