Evaluation of commercial and prototype traps for Xylotrechus arvicola (Coleoptera: Cerambycidae), an insect pest in Spanish vineyards

Background and Aims An important factor for the success of a mass capture strategy to control cerambycids involves the selection of an effective trap–lure combination. Therefore, the aim was the evaluation of traps with lures and their efficacy for monitoring and mass trapping of Xylotrechus arvicola. Methods and Results Three trap types, Crosstrap, Delta and Screen‐adhesive, with lures baited with ethanol, were evaluated during 4 years in vineyards of two cultivars. The Crosstrap obtained the greatest catches during 2013 in Tempranillo (29.6 adults/trap) and Prieto Picudo (12.9 adults/trap). All trap types showed similar periods of greatest catches in both cultivars. Conclusions The Crosstrap achieved the greatest number of adults captured in both cultivars. The Delta and Screen‐adhesive had few catches. The Tempranillo has proved to be more susceptible to attack by this insect than Prieto Picudo. The capture period varies from 30 to 50 days in the same cultivar in different years. Low temperature during spring delays the appearance of adults. Significance of the Study The Crosstrap baited with ethanol captured the greatest number of X. arvicola adults. This trap can be used to improve monitoring of adult emergence and for controlling this pest by mass trapping.
