Abstract

The one-host biological north form / ecotype of Hyalomma scupense Schulze, 1919 (Acari, Ixodidae) is reported for the first time in Turkey herein. Following the first detection of the tick, a longitudinal field study was carried out to fill gaps in the data concerning its biological features. This study also aimed to determine how the monthly activation dynamics of this relatively cold climate-adapted species is characterized under the influence of the warm summer subtype of the Mediterranean climate. During this study, which was carried out on a monthly basis in 2014, H. scupense was found on cattle from 5 out of 18 villages screened in Thrace (the European part of Turkey). The field study revealed that i) this north ecotype of H. scupense exhibits winter one-host behavior beginning in October (with larval stages) and ending in April (with engorged adults); ii) engorged females detach from the cattle, drop on the floors of barns during night and accumulate on piled bedding contaminated with slurry manure; iii) in the late spring, engorged females lay eggs, and larvae hatch in the same area; and iv) larvae become active in autumn as the weather grows cooler. The results indicated that although one-host H. scupense is known to be distinctly adapted to cold conditions, it can also be effectively established in relatively temperate regions and complete its life cycle with some modifications in the timing of its monthly activation dynamics.
