Mule Deer Hair loss in Yakima: Dr. Briggs Hall and Region 3 staff visited a landowner who reported hair loss in the mule deer for which he was providing winter feed. Staff immobilized a subject with mild hair loss and collected lice and sent samples in to Dr. Jim Mertins at the National Veterinary Services Laboratory. Dr. Mertins has identified the lice as Bovicola tibialis, another exotic louse species separate from the exotic louse Bovicola cervicola, which is causing hair loss in the black tailed deer. Bovicola tibialis is the common louse of fallow deer. B. tibialis has been identified in North America on only four previous occasions. The locations were California and British Columbia. Per Dr. Mertins, B. tibialis is a parthenogenic species (no male required for reproduction) and as such can spread more efficiently. The other louse samples sent were all from black tailed deer suffering from hair loss and were identified as B. cervicola.
