| Das pflanzliches Insektizid Pyrethrum ist für den ökologischen Obstbau ein unverzichtbarer Bestandteil der Pflanzenschutzstrategie. Die Breitbandwirkung und die entsprechenden Auswirkungen auf die Arthropodenfauna ist zwar zu berücksichtigen, kann aber im Freiland nicht mit Breitenwirksamkeit synthetischer Insektizide wie z.B. Pyrethroide oder Parathion verglichen werden. Der schnelle Abbau der Pyrethrine in Verbindung mit einer relativ geringen Mortalität sind gute Voraussetzungen für eine rasche Regeneration der Abundanz betroffener Arthropodengruppen. Das neu zugelassene pflanzliche Insektizid NeemAzal-T/S stellt eine sehr wertvolle Bereicherung der Pflanzenschutzstrategie im ökologischen Obstbau dar. Es gibt allerdings noch einige Zulassungslücken... |

| This report describes the working processes and results of the bachelor project “Redesign of insect trap for biological pest control”. The project is based on research on pheromones and the project SoftPest Multitrap. Copenhagen Uni-versity’s Science and Life Sciences, more specifically Department of Plant andEnvironmental Sciences has researched and developed the pheromones for mass trapping of the Strawberry Blossom Weevil (Anthonomus Rubi) and the European Tarnished Plant Bug (Lygus Rugulipennis). The user processes associated with the insect trap were analysed through fieldstudies and a participatory design process. The analysis resulted in a design brief and a product specification.The SoftPest Multitrap proved to be difficult toimplement in the... |

| The study focused on changes of rhizosphere microbial communities in apple trees in long-term replanted orchards of Central Europe, aiming at developing cropping practices to mitigate replant problems. It started from the evidence of a previous study which showed that a slight modification of root-colonizing fungal communities was responsible for a great increase of plant growth in soil samples which had previously been subjected to a gamma-irradiation cycle (25 kGy for 8 h), as compared to that observed in the corresponding untreated native soils. The study was performed on rhizospheric soil from nine multi-generation apple orchards after a plant growth assay with M9 rootstock plantlets. PCR-DGGE analysis of soil DNA was performed to evaluate fungal and... |

| Biologisch geteeld kleinfruit is enorm geliefd bij het grote publiek. Biotelers van houtig kleinfruit kampen echter met een aantal probleemplagen en -ziekten die ze zonder de krachtige chemische gewasbeschermingsmiddelen het hoofd moeten bieden. Daarom werd in 2013 in het kader van een CCBT-project in gezamenlijk overleg gezocht naar alternatieve oplossingen voor de bestrijding van deze plagen en ziekten. In de loop van dit project werden diverse overlegmomenten georganiseerd tussen telers, voorlichting en onderzoekers waarin de prioriteiten voor het onderzoek werden bepaald (dit uiteraard vooral door de biotelers zelf). Bedrijven waar proeven konden plaatsvinden werden in overleg met het Bio-bedrijfsnetwerk kleinfruit geselecteerd (het gaat dus om ‘on... |

| 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... |

| Introduction: For many insect species, pheromones and host plant volatiles are of major importance in mate finding and host plant location. Therefore, there is potential for using these interactions to develop new strategies and effective control measures. The strawberry blossom weevil (Anthonomus rubi), the European tarnished plant bug (Lygus rugulipennis) and the raspberry beetle (Byturus tomentosus) cause large losses (10->80%) in both conventional and organic strawberry and raspberry production. We investigated whether the natural semiochemical mechanisms of these key pests can be exploited to develop effective traps for their management through mass trapping. Methods: Attractive traps and lures with host plant volatiles and pheromones were... |

| Die Kirschessigfliege (Drosophila suzukii) wurde 2008 aus Südostasien nach Europa eingeschleppt 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. Holunder und Schneeball dienen als Wirtspflanzen. Der Hauptschaden entsteht durch den Larvenfrass 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 Weinreben 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 in der Schweiz im Jahr 2014 erstmals... |
