Abstract: A pilot-project was conducted in Piedmont to determine if insecticidal sprays against Scaphoideus titanus, the vector of grapevine 'flavescence dorée' disease, can be decreased in case of low populations of the leafhopper. Field samplings included a sequential sampling of nymphs on leaves and yellow sticky traps for capturing adults in vineyards subject to different pest management strategies. Population levels of S. titanus were lower in conventional than in organic vineyards, the latter being always more variable, suggesting some problems in the distribution of the active ingredient. The vineyards that were under the proposed threshold received just one spray, however no increase in the presence of S. titanus was observed. As a result, provided a suitable sampling plan, it is possible to reduce insecticidal sprays against this leafhopper vector.
