Mating disruption (MD) is a well known efficient technical crop protection against grape berry moths used allover European vineyards. The method is specific and requires observations of non target pests like microscopic arthropods under the foliage. In 2010, a skill transfer between INRA and an agricultural supplier started in Medoc AOC region near Bordeaux. Three fauna monitoring occurred during the growing season: flowering, bunch closure and maturity. Biodiversity was always important in the monitored vineyards, and this concerned both beneficials and pests. Typhlodroms were the most represented in the leaf communities. The history of MD did not seem to influence the biodiversity observed, and we found no clear effect of weed cover occurrence. We report the others species which were counted by our methodology.
