TUCSON, Ariz. — Two University of Arizona Cooperative Extension experts are available for comment on recent reports of tick epidemics in the U.S. and Mexico.
The brown dog tick has been found throughout the U.S. and Mexico, and is driving an epidemic of Rocky Mountain Spotted Fever in northwest Mexico. Concerns in the U.S. center around the border states of California and Arizona.
At the same time, the Asian longhorned tick is spreading throughout the East Coast.
"The Asian longhorned tick is spreading rapidly in eastern states. This tick species is remarkably adaptable — females can reproduce without males, laying thousands of eggs at a time. They utilize an extremely broad host range including mammals and birds, and serve as effective vectors of numerous disease causing pathogens. It really has almost all of the worst-case characteristics a tick could have," said Dawn Gouge, an entomologist with UA Cooperative Extension.
