To maintain the practice of organic viticulture while protecting us from the grape-worm. We avoid the use of pesticides and chemicals. We attach containers to the vines which give off phéromones for 6 months.  As the male butterfly seeks the femal by the scent of pheromones, the continers that give off the scent make the female butterfly all the more difficult to find, which result in less incidence of mating in the vineyard.  The butterflies are dangerous for the vine, as their caterpillars feed off the leaves and cause marked decreased quality of the grapes, which are more prone to attack by fungi.
