| The Spotted wing drosophila, Drosophila suzukii, is an invasive pest in Europe and North America, infesting various soft-skinned fruits. Because D. suzukii attacks ripening fruits shortly before harvest, only insecticides with short pre-harvest intervals can be applied. Alternatively, kaolin, lime and rock dusts are non-toxic to non-target organisms, but the whitish coating on fruits potentially deters oviposition of D. suzukii. Therefore, we tested oviposition deterrence and insecticidal effects of such substances. Female D.suzukii flies were exposed to treated blueberries under laboratory conditions for 24 hours. Kaolin, clinoptilolite, clinoptilolite + Heliosol (pine-oil based wetting agent) and calcium carbonate significantly reduced oviposition,... |

| Drosophila suzukii is a major pest of soft-skinned fruits, and insecticides are often used to prevent fruit damage caused by oviposition. As D. suzukii produces many generations per year, repeated insecticide applications are required. Furthermore, D. suzukii attacks ripening and ripe fruits shortly before harvest. Therefore, the use of synthetic insecticides is limited by long pre-harvest intervals and maximum residue limits. To be able to offer producers immediate and sustainable solutions, we tested 25 natural crop protection products with three different application methods in a laboratory screening. We show that application method is an important factor for the efficacy of the tested products. Of six natural insecticides, only Spinosad was toxic for... |

| Die Kirschessigfliege hat sich in Deutschland und anderen europäischen Ländern etabliert. Auch wenn ihr Auftreten nicht in jedem Jahr einen wirtschaftlichen Totalschaden verursachen wird, gilt es trotzdem Maßnahmen zu ergreifen. Im Rahmen der Bachelorarbeit „Maßnahmen zur Bekämpfung von Drosophila suzukii im biologischen Weinbau“ wurden einerseits in einer Literaturstudie die vorbeugenden kulturtechnischen Maßnahmen zur Befallsprävention analysiert. Im Rahmen einer guten fachlichen Praxis sollten diese auf die mögliche Anwendung von den ProduzentInnen geprüft und auf individuelle Gegebenheiten in den jeweiligen Weinbaubetrieben angepasst werden. Andererseits wurde im Rahmen der Arbeit die Wirksamkeit von 28 Pflanzenschutzmitteln, die für den ökologischen... |
