To know the ethiology, species distribution, epidemiology, and tick species involved as vectors of bovine tick-bome diseases in Menorca island, one year sampling of ticks and blood samples from cattle will be performed. PCR probes will be routinarily used to check for the presence of Babesia bovis, B. bigemia, Theileria annulata, and Anaplasma marginale in both ticks and bovine samples. Tick species composition and the role played in the effective transmission of diesases will be investigated by the statistical association (stepwise discriminant analysis) between the prevalence of ticks instars and several climate variables, obtained from a dedicated netwrok of computerizad climatic recorders. A simulation model will be build-up to follow up predictive analysis of tick populations. A gegraphical information system will be used to map geographic data, land use analysis, and pattems of distribution of tick species, prevalende, and seasonal activity. Geostatistical methods (standard cokriging) will be used to predictive output of epidemiological features, thus providing a toll for the control of tick-bome diseases in Menorca island. The final goal of the proposed project is to control the tick-bome diesases, to improve the diagnoses procedures, and to increase the economical performance of cattle use of integrated pest management.
