    In September 2011, a single Drosophila suzukii fruit fly was found in Belgium for the first time. Soft and stone fruit production is an important segment of the Belgian agriculture production, thus an intensive monitoring of the spotted wing drosophila (SWD) was initiated throughout Belgium. In 2012, several research institutes (CRA-W, FASFC, GFW, ILVO and pcfruit) collaborated in setting up a monitoring survey at 53 locations. Either a handmade trap filled with the attractants apple cider vinegar or wine & wine vinegar, or the commercially available Droso trap® were used. SWD was detected at 26% of the monitoring sites. The first SWD flies were caught starting from the second half of July. Higher numbers were found later in the growing season, with a maximum in October 2012. This survey was carried on during 2013 and 2014 by pcfruit and CRA-W (Project FLY ALERT), screening 53 locations by means of self-made apple cider vinegar traps. In 85% of the screening sites D. suzukii was present. SWD was captured on strawberry, raspberry, blackberry, cherry and grapes, but also on wild cherry trees in natural sites. Adults were also detected in traps nearby fruit trading points. As a result of the exceptionally mild winter of 2013-2014, D. suzukii was spotted throughout the winter and spring, albeit generally at relatively low numbers. In 2014, SWD was again observed up to December, yet they seemed to occur in higher numbers than in previous years. A recently started 4 year research project will further investigate the phenology, biology and other key characteristics of this new pest species in order to develop sustainable integrated pest management strategies.
