Longitudinal monitoring of Culicoides in Belgium between 2007 and 2011 : local variation in population dynamics parameters warrant cautious use of monitoring data

BACKGROUND : Several European countries suffered important economic losses during the past decade due to the emergence of bluetongue and Schmallenberg viruses. Both are viruses of veterinary importance and are spread by Culicoides spp. This triggered many European countries to start Culicoides population monitoring. Recently a one year monitoring study at 16 sites in Belgium revealed that important variation existed in Culicoides abundance and species diversity between collection sites. In order to analyze whether this variation is consistent over years, a detailed analysis of monitoring data... Mehr ...
