The Asian longhorned tick is spreading across Arkansas. The tick can infect cattle with Theileriosis, a disease that can lead to weakness, jaundice, miscarriage, and sudden death in livestock.
Andrew Fidler is Arkansas’ head veterinarian. Speaking to farmers at a webinar in May, Fidler said veterinarians are required to report confirmed cases of the disease to state or federal agencies.
"However there’s no state or federal action associated with theileriosis in terms of the animal or the herd that the animal comes from," Fidler said.
Female Asian longhorned ticks can lay eggs without a mate. This allows them to form large infestations on a single animal and rapidly spread to new areas.
Farmers can manage the pest with insecticides or prescribed burns, says Kelly Loftin, an entomologist with the University of Arkansas’ Division of Agriculture.
"Maintain tick control the best you can, treat all animals in the herd, brush all the pastures, and you may consider testing symptomatic animals when you start talking about theileriosis" Loftin said.
The tick has established itself in ten northern counties since Arkansas’ first confirmed sighting in 2018. Fifteen have reported confirmed cases of Theileriosis, including Arkansas and Cleveland counties, both in the southern part of the state.
