CORTES, J. A. CHANGES ON FREQUENCY AND DISTRIBUTION OF TICKS AND ITS RELATIONSHIP WITH THE GLOBAL WARMING. Rev. Med. Vet. Zoot. [online]. 2010, vol.57, n.1, pp.48-57. ISSN 0120-2952.

The climatic change could be affect the frequency and distribution of the vector populations, like ticks, in many different places around the world, nowadays. Nevertheless, there is a number of factors explaining changes in the incidences of vector-borne diseases, e.g., rapid growth of human population, socio-economic conditions, changes of landscape, and international trading. I am presenting basic concepts about changes of the climate in a biological and epidemiological context. It has been documented that microorganisms transmission rates are higher with shorter life cycles of ticks. I am hereby presenting the main strategies designed to limit migration and abundance of tick populations. Although tick control within farm animals uses chemical acaricides, several strategies could be added by an integrated pest management program. It poses an effective and sustainable alternative.
