Development and efficacy of Droskidrink, a food bait for trapping Drosophila suzukii


Abstract: Droskidrink is the name given in Trentino, Italy, to a food bait for attracting Drosophila suzukii (Matsumura) (Diptera Drosophilidae). It was originally designed in 2011 by a FEM team led by Alberto Grassi. The Droskidrink consists of a mixture of apple cider vinegar (75%), red wine (25%) and 20 g/l of unrefined sugarcane. Its efficacy in comparison with other available food baits has been evaluated in different field trials (monitoring, mass trapping, attract-and-kill) during the period 2011-2014. Results of these experiments demonstrated that Droskidrink is highly effective as food attractant for D. suzukii and suggests further efforts for the development of monitoring and control methods based on Droskidrink baits.
