| Orchards, as intensive cropping systems, often have low diversity of plant species, which limits the promotion of natural enemies for pest control. The implementation of agri-environmental schemes, such as flower strips, could enhance biological control. We developed perennial, multifunctional flower strips with native plant species. In the second and third year after sowing, plant diversity and ground cover between flower strips (FS) in the drive alleys and the spontaneous orchard vegetation in control plots (Cont) were compared in 19 experimental blocks of eight organic apple orchards in six European countries. On average 73.7% of the sown plant species were established and plant diversity of FS was on average 43% higher than in Cont. Multivariate... |

| Drosophila suzukii is a major pest of soft fruits. Baited traps are widely used for monitoring and mass trapping: different commercial baits, different recipes for home-made baits as well as several literature references on attractive compounds are available. In a series of 15 laboratory experiments we compared the attractiveness of different baits for D. suzukii: the commercially available Dros’attract (Biobest Belgium NV) and the Gasser-bait (Biologische Becherfalle für die Kirschessigfliege Drosophila suzukii; Riga AG), a 4-Component-attractant (Cha et al., 2013) and a self-made wine-vinegar-bait (50 % water, 40 % apple cider vinegar, 10 % red wine, 0.05 % acetone, 0.0125 % soap). Furthermore, we tested if different bait amendments (β-Cyclocitral,... |

| 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,... |

| Même si la présence de la drosophile du cerisier (Drosophila suzukii) dans les vignobles suisses a provoqué une grande inquiétude auprès des viticulteurs en 2014, les expériences acquises ces deux dernières années montrent que la vigne doit être considérée comme une plante hôte secondaire. Malgré cela, des oeufs peuvent être pondus dans les baies de divers cépages. Avec l’aide des services cantonaux, nous avons échantillonné plus de 90 000 baies dans 500 parcelles en 2015, ainsi que 150 000 baies dans 600 parcelles en 2016. L’analyse de ces données montre que la sensibilité du raisin augmente avec la maturation, que les cépages rouges Acolon, Cabernet Dorsa, Cornalin, Divico, Dornfelder, Dunkelfelder, Galotta, Garanoir, Humagne rouge, Mara, Regent et Syrah... |

| This project evaluated the efficacy of seven different organic plant protection programs against the black cherry aphid Myzus cerasi (MYZUCE) in a low stem cherry orchard. The standard paraffin oil (Weissöl) applied after bud swelling (BBCH 03) significantly reduced the number of infested long shoots and aphid colony size, represented by the number of curled leaves. Additional treatments with Pyrethrum (Pyrethrum FS) and Neem oil (Neem Azal T/S) added no further efficacy. Neem oil and Majestik applied twice showed only limited efficacy. A test oil was clearly less efficient than the standard paraffin oil. Ant baits placed on the stems after bud swelling to prevent ants from promoting aphids offered an interesting, sustainable control approach should for... |

| Die Kirschessigfliege (Drosophila suzukii) wurde 2008 aus Südostasien nach Europa einge-schleppt und verursacht seitdem z.T. massive Ertragsausfälle. Sie befällt alle Weichobstarten, wie z.B. Beeren, Kirschen, Zwetschgen und Trauben. Auch viele wilde Pflanzen, wie z.B. Ho-lunder und Schneeball dienen als Wirtspflanzen. Der Hauptschaden entsteht durch den Larven-frass an den Früchten. Da der Generationszyklus sehr kurz ist und daher mehrere Generationen parallel auftreten, kommt es zu einem starken Befallsdruck im Spätsommer und Herbst. Da Trauben länger hängen als z.B. Beeren und die Lese erst im Herbst stattfindet, ist in Reben mit einem besonders hohen Befallsdruck zu rechnen. Aufgrund der Witterungsbedingungen wurden im Jahr 2014 erstmals starke... |

| Perennial flower strips improve the effectiveness of biological pest control by predators and parasitoids in fruit production. The guide presents results from the European EcoOrchard project and other studies, explains how the flower strips function, introduces suitable plants and describes step by step the procedure for planting and maintenance. The information is supplemented by information on the costs and possible disadvantages of the flowering strips. |

| Mit Hilfe der kantonalen Fachstellen für Weinbau wurden 2015 und 2016 gegen 250’000 Traubenbeeren in über 600 Parzellen auf Eier der Kirschessigfl iege (KEF, Drosophila suzukii ) überprüft. Die Datenauswertung zeigt, dass die Anfälligkeit der Trauben mit der Beerenreife steigt, dass insbesondere die roten Rebsorten Acolon, Cabernet Dorsa, Cornalin, Divico, Dornfelder, Dunkelfelder, Galotta, Garanoir, Humagne rouge, Mara, Regent und Syrah stärker gefährdet sind und dass weichhäutige Rebsorten vermehrt befallen werden. |

| La drosophile du cerisier (Drosophila suzukii), qui est arrivée en Europe en 2008 depuis le sud-est de l’Asie, peut provoquer des dégâts considérables. Elle s’attaque à tous les fruits tendres comme les baies, les cerises, les prunes et le raisin. Et de nombreuses plantes sauvages comme le sureau et la viorne obier lui servent de plantes-hôtes. Les dégâts sont principalement causés par les larves qui mangent les fruits de l’intérieur. Vu que le cycle de reproduction est très court et que plusieurs générations apparaissent en parallèle, c’est en fin d’été et en automne que la pression d’attaque est la plus forte. Il faut s’attendre à une pression d’attaque particulièrement forte dans les vignes puisque le raisin est récolté plus tard que la plupart des... |
