Monitoring made easy
Since the presence of Drosophila suzukii has been identified in orchards, the plots concerned have been fitted with traps. Traps are used to acquire biological knowledge about the fly, and also to help with the timing of control measures. The traps, which are easy to make, are homemade using a red plastic bottle, red being an attractive colour for D. suzukii (Figure 1). Twenty 4 mm diameter holes were drilled in half of the lower part of the bottle using a heated nail: to facilitate emptying the liquid bait inside when taking readings, part of the side of the bottle should not have holes.
