Additional to determination of tick species during the research, the sex ratio and the monthly influence of microclimate conditions (temperature, relative humidity and precipitation quantity) on the dynamics of populations of ticks were followed. Obtained results indicate the importance of the impact of climatic factors on the population dynamics of some species of ticks as well as the dynamics and abundance of different sexes within established species of ticks.

Sheep production is an example of a sustainable production fully integrated within the local rural development. One of the main threats on the outdoor breeding of sheep is parasitism. Ticks are nuisances and vectors of several diseases agents. The distribution of ticks appears to be changing, with spread to previously unaffected areas. Tick and tick-borne disease control is one of the major components of animal health program protecting livestock in the developing countries, which reflects impact on the livelihood of resource-poor farming communities. Taking into consideration the negative impact on the health status of the livestock, also the direct and indirect economic losses, it is necessary to examine the tolerance and resistance of certain species against diseases. It is one of the most important elements of the strategy of selection and screening for resistant animals. The aim of this study was to determine the tick species persisting in 45 tested autochthonous Zackel sheep flocks, and examine their seasonal occurrence from March 2010 to January 2011, in the region of South Serbia. The result showed that Ixodes, Dermacentor, Ripicephalus and Haemaphysalis were the most abundant ticks found, affecting 50.40% tested sheep. The result of this study is a survey of tick species from autochthonous Zackel sheep in Serbia and implication of possible preventions measures for diseases caused and transmitted by ticks.
