2012 Annual Report 1a.Objectives (from AD-416): Develop, field test, and refine technologies to control ticks feeding on white-tailed deer and other wild ungulate species. 1b.Approach (from AD-416): Determine comparative palatability of ivermectin and doramectin medicated corn. Demonstrate proportional free daily intake of macrocyclic lactone medicated baits vs. high protein pelleted deer ration. Field test and continue development of the 3rd generation automatic collaring device. Conduct efficiacy trial of automatically applied neckbands in controlling ticks feeding on white-tailed deer. Field test and continue development of devices to exclude non-target animals from accessing '4-Poster' Deer Treatment Bait stations. Determine behavioral interactions of white-tailed deer with medicated molasses licks intended for cattle. 3.Progress Report: During FY 2012, ARS cooperated with the Kerr Wildlife Management Area on several occasions regarding biology and ecology of white-tailed deer and the KWMA also served as a source for lone star ticks that are colonized and used for acaricide screening tests in Kerrville, TX, and also are distributed to ARS cooperators in Beltsville, MD, for their studies on tick repellents.
