Abstract: In 1993, BASF ampulla dispensers containing pheromone of grape vine moth L. botrana, were hung exclusively along a 16 ha rectangle in a vineyard situated at Perroy in the Lake Geneva Region. Pheromone and bait traps were distributed inside and outside of the dispenser belt. Virgin females were tethered throughout the vineyard. Tagged males were released inside the dispenser belt.
During first and second generation flight periods, male catches and tethered female matings inside the dispenser belt were reduced by more than 90% compared to the outside. About 5% of the tagged males released inside the dispenser belt were caught in pheromone traps: most of them outside of the belt, some more than 800 m from the release point. First generation damage was 29.3% outside and 24.5% inside. Compared to reduction of catches in traps or matings by tethered females, damage reduction inside the belt was low: on the average 16.5%. However, this trial shows that mating disruption techniques could eventually be conducted by distributing a high density of dispensers along the edge, and by adding a large spaced grid of dispensers inside vineyards.
