Abstract
Development and maintenance of laboratory tick colonies provides reliable access to a variety of tick species at multiple life stages. Advances in techniques for the membrane feeding of ticks reduce the number of laboratory animals needed for colony maintenance. In the present study, modifications to the existing protocol for in vitro feeding of the argasid species Ornithodoros tartakovskyi were made. Adult O. tartakovskyi ticks of both sexes were allowed to feed to engorgement using a novel membrane feeding apparatus in a six-well plate format with well-inserts of laboratory-grade, wax sealing film. Of the 193 ticks placed on the membrane, 89% (n = 172) fed until engorgement and subsequently detached. The modified feeding method described will aid in future laboratory tick-based research because it allows for increased containment, ease of sorting, successful in vitro feeding, easy replacement of blood meals and a reduction in the total volume of blood meal required.
