| 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,... |

| Essential oils can have an impact on pollen beetle (Meligethes spp.) host plant location behaviour. Lavender oil (Lavendula angustifolia) showed the highest repellency value in a previous laboratory study that compared five different essential oils (Mauchline et al., 2005). However, lavender oil is one of the most expensive essential oils – a fact that could seriously hamper on-farm implementation of this strategy. To find a cheaper essential oil with comparable efficacy to lavender oil, we compared the essential oils of Mentha arvensis, Eucalyptus globulus, Melaleuca alternifolia, Citrus sinensis, Citrus paradisi, Citrus limon, Juniperus mexicana, Abies sibirica, Illicium verum, Gaultheria procumbens, Cymbopogon flexuosus, Syzygium aromaticum, and Litsea... |

| Versuche mit Gesteinsmehl Der Rapsglanzkäfer gilt als einer der wichtigsten Schadorganismen im Schweizerischen Rapsanbau. Gesteinsmehl, eingesetzt zur Pflanzenstärkung, könnte durch seine repellente, frasshemmende Wirkung den Schädlingsbefall vermindern. Die Applikation von 30 kg Klinospray mit dem Zusatz von 2 l Heliosol und 600 l Was-ser pro Hektar war problemlos mit einer normalen Feldspritze möglich. Unter den tro-ckenen Witterungsbedingungen im Jahr 2010 konnte der Besatz mit Rapsglanzkäfern durch die Applikationen um 45-50% reduziert werden, wobei der Wirkungsgrad mit fortschreitender Pflanzenentwicklung abnahm. Die Versuche wurden an 6 Standorten mit unterschiedlichen Witterungs-und Bodenbedingungen, sowie mit verschiedenen Rapsorten... |

| Obwohl der Flug der Rapsglanzkäfer im Jahr 2008 schon im Februar einsetzte, blieben die Käfer an den meisten Standorten unter der Schadschwelle. Die kühle Witterung bis Ende April bremste die Aktivität der Käfer. Ende April waren bereits die ersten Rapsblüten geöffnet, sodass die Rapsglanzkäfer kaum noch Schäden verursachen konnten. Zu kritischen Situationen kam es in nur warmen Lagen mit schwerem, kühlen Boden (Fricktal): Die warmen Temperaturen sorgten für eine starke Käferaktivität, während die kühlen Böden das Pflanzenwachstum und die Blütenentwicklung bremsten. |

| The European cherry fruit fly, Rhagoletis cerasi Loew (Diptera: Tephritidae), is a highly destructive pest of sweet cherries in Europe. Up to 100% of the fruit can be infested. Methods for controlling this pest are limited in organic agriculture as well as in integrated production, as the insecticide currently used (Dimethoate) is being challenged due to problems of ecotoxicity and residues. Alternative methods for cherry fruit fly management are therefore needed. The aim of this thesis was to develop a new control strategy for R. cerasi using entomopathogenic fungi. In a first step, the effects of six fungus isolates on the mortality of different life stages of R. cerasi were assessed in a series of laboratory experiments. All fungus isolates caused... |

| Demand for organic cherries offers producers a premium price to improve their commercial viability. Organic standards require that producers find alternatives to pesticides. Soil treatments to control the European cherry fruit fly Rhagoletis cerasi (L.)(Diptera: Tephrididae) appear to be an attractive option. However, soil treatments can only be effective if the migration of flies is low, because mature flies may migrate from near-by trees for oviposition. To examine the general potential of soil treatments and to understand the dispersal and flight behaviour of R. cerasi within orchards, experiments using netting to cover the soil were conducted in two orchards with different pest pressure during two years. The netting reduced flight activity by 77% and... |

| Autumn applications of sulphur – a new approach to control the pear leaf blister mite Eriophyes pyri. Abstract: The pear leaf blister mite can cause severe damage to pear leaves and young fruits in some regions. Due to hidden living inside leaf blisters, the mites are largely protected against the impact of plant protecting agents. Until now, treatments with mineral oil or rape oil in early spring, during the time when the mites leave their hibernation sites under the bud scales to invade the young leaves and blossoms, are the only possibility to control these mites in Swiss organic fruit growing. The aim of this study was to examine the effects of sulphur, mineral oil and Surround®WP applied after harvest during the time, when the mites leave their... |
