First records of Dermacentor albipictus larvae collected by flagging in Yukon, Canada
Abstract Background The winter tick ( Dermacentor albipictus ) has garnered significant attention throughout North America for its impact on wildlife health, and especially for moose ( Alces alces ), where high tick burdens may result in host hair loss, anemia, and can prove fatal. The environmental...
