Abstract We applied a process-driven model to evaluate the impact of climate scenarios for the years 2020 2050 and 2080 on the life cycle of Hyalomma marginatum ticks in the western Palearctic. 8 Other strains of BKNV were isolated from a mixed pool of Aedes caspius and Culex hortensis mosquitoes in Kyrgyzstan 9 and from Ornithodoros lahorensis and Dermacentor marginatus ticks in Transcaucasia. Development rates increased mortality rates in molting stages decreased and the survival rates of questing ticks decreased in wide territories of the Mediterranean basin.

The identification of Hyalomma species is far from easy and distinguishing characteristics for H. A suitable tick climbing bioassay based on the questing behaviour of ticks was used to test for repellency. High percentage repellency range 70-100 was shown at all concentrations of the essential oil of L.

The prototypical strain of Batken virus BKNV LEIV-K306 was isolated from Hyalomma marginatum ticks collected from sheep near the town of Batken in Kyrgyzstan in April 1970. Hyalomma marginatum a two-host tick is found in North Africa and southern Europe. We generated annual models of environmental suitability for the tick in the period 19702018 using harmonic.
