The effect of irrigation on the incidence of pests was investigated in two vineyards located in north-eastern Italy in 2006. Irrigation was performed 2-3 times during the experimental season by a micro-spray system. The leafhopper Empoasca vitis Göthe was the most frequent pest in the two vineyards. Its seasonal abundance was monitored by examining leaf samples. Empoasca vitis population densities were affected by irrigation, and higher levels of this pest were recorded on irrigated vines in particular.
