Lumpy skin disease (LSD) is among a number of vector-borne diseases (VBDs) threatening the Balkans and therefore, preventing feeding of insects on cattle would reduce the spread of VBDs. In order to test the efficiency of Livestock Protective Fences (LPF) in the protection of dairy cattle from insect bites, a case-control study was conducted, in the districts of Nišava, Pirot and Pčinja, Southern Serbia. It consisted in comparing the number of biting flies collected within time, between 10 farms protected with LPF and 10 non protected ones. The insects were collected using two types of traps; the monoconical Vavoua trap set outside in between forested areas or rivers and the actual farm, and the BGsentinel trap baited with CO2, placed in proximity of the cattle but outside the stable. Vectors were collected every 15 days for 48 hours from May to October 2018 and kept in vials containing 70% of ethanol. Catches per trap were separately stored and for each trap, insects were classified according to species and sex and then counted. Data on milk parameters were analyzed separately, on data collected within protected farms, before and after the LPF deployment, and on data without protection at all. It was not possible to detect a direct impact of LPF on vector densities but the number of bacteria colonies (CFU) values were reduced. Some corrections/adaption in the methodology used may lead to better impact.
