A new visual trap for Rhagoletis cerasi (L.) (Diptera: Tephritidae). Organic Eprints
Daniel, Claudia; Mathis, Samuel; Feichtinger, Georg.
The European cherry fruit fly, Rhagoletis cerasi (L.) (Diptera: Tephritidae), is the most important pest of sweet cherries in Europe. The aim of our experiments was to develop a new, cost-efficient, lead chromate-free and more eco-friendly trap for monitoring and mass trapping of R. cerasi. Five different-colored yellow panels and three different trap shapes were compared to a standard Rebell® amarillo trap in three experimental orchards in 2012. Trap color F, with a strong increase in reflectance at 500–550 nm and a secondary peak in the UV-region at 300–400 nm, captured significantly more flies than the standard Rebell® amarillo trap. Yellow traps with increased reflectance in the blue region (400–500 nm) were least attractive. Trap shape was of minor...

Æbler under tag er pletfri Organic Eprints
Bertelsen, Marianne.
Hvad sker der hvis man sætter et tag over æbletræer? Kan man så dyrke æbler uden at sprøjte og uden at få frugten skadet af svampeangreb? Det har Aarhus Universitet undersøgt, og resultaterne er meget positive. Et lille tag har vist at gøre en stor forskel i forhold til at forebygge svampesygdomme, der angriber æbler.

Alles Kirschessigfliege oder was? Organic Eprints
Koller, Martin; Daniel, Claudia.
Die Kirschessigfliege Drosophila suzukii wurde 2008 nach Europa eingeschleppt. Im Mittelmeerraum wurden 2011 starke Schäden vermeldet. In diesem Jahr ist mit Schäden auch nördlich der Alpen zu rechnen. Die Fliegen befallen alles Weichobst (Beeren, Kirschen, Trauben), sowie viele wilde Pflanzen. In diesem Jahr sollten alle sensiblen Kulturen mit Apfelessig-Fallen überwacht werden. Zur Befallsvorbeugung werden der Einsatz von engmaschigen Netzen (0.8 mm), sowie eine frühzeitige, vollständige Ernte und das Vernichten befallener Früchte empfohlen.

Bekæmpelse af hindbærsnudebillen Organic Eprints
Wibe, Atle; Sigsgaard, Lene.
Without effective means the strawberry blossom weevil can cause great yield losses in strawberry production. The weevils lay eggs in flower buds and partially severs the bud from the plant. By developing traps baited with pheromones and plant volatiles we search to manage weevil populations to reduce damage on the strawberry plants.

Flying doctors zur Grauschimmel Bekämpfung und als Bestäuber im ökologischen Erdbeeranbau - erste Untersuchungsergebnisse im BICOPOLL Projekt Organic Eprints
Kreipe, Victoria; Boecking, Otto.
Organic berry and fruit production suffers heavily from the lack of effective disease and pest management tools, and from inadequate insect pollination at times. As a consequence, the expanding demand on organic berries cannot be filled today. BICOPOLL expects to change this, and to significantly improve the yield and quality of organic fruit and berry production and thus, farm economics. We will use bees to (i) target deliver biological control agents to the flowers of the target crops to provide control of problem diseases, and to (ii) improve the pollination of organic horticultural crops. We will provide a pan-European case study on protecting organic strawberry from its most important disease, the grey mould. We will improve the efficiency of the...

Migration und Ausbreitung der Kirschfruchtfliege innerhalb von Obstanlagen – Möglichkeit der biologischen Bodenbehandlung Organic Eprints
Daniel, Claudia; Wyss, Eric.
The European cherry fruit fly (Rhagoletis cerasi) is the only pest insect which makes a insecticide treatment of cherry fruit necessary. With regard of residue free cherries a biocontrol method for R. cerasi by soil applications seems attractive. However, soil treatments can only be effective if the migration of flies is low. In order to examine the potential of soil treatments and to understand the dispersal behaviour of R. cerasi in orchards, experiments using nettings to cover the soil were conducted. The experiments were arranged in commercial, organically managed orchards. The nettings reduced fruit infestation by 90%. In addition, it was shown that the flies move only very short distances (less than 5 m) within orchards. Thus, soil treatments...

Pest Management in organic Apple, Pear and Stone Fruit Organic Eprints
Daniel, Claudia; Matray, Silvia; Stoeckli, Sibylle; Niggli, Urs.
Holistic approaches to pest management that aim at maximising self-regulation and resilience of orchards are a key goal in organic farming (see chapter 2). Pest management starts even before planting an orchard by site selection, orchard layout, planting systems (tree densities and pruning system), choice of cultivar and rootstock as well as cultivation techniques. Cultivation techniques and measures applied for disease control can also influence the dynamics of pest insects within orchards and need to be included in a holistic system view. In addition, the use of flowering strips to enhance natural enemies is a field of intense research. Direct control methods using biocontrol organisms or bio-insecticides are available for many pest insects. However,...

Regulierung der Kirschenfliege (Rhagoletis cerasi) - Bericht 2011 Organic Eprints
Häseli, Andreas; Daniel, Claudia.
Für einen guten Wirkungsgrad beim Einsatz von Naturalis-L müssen die Anwendungsempfehlung (Behandlung alle 7 Tage, maximal 7 Tage Wartefrist bis zur Ernte) exakt eingehalten werden. Schon kleinere Fehler führen zu einem empfindlichen Einbruch in der Wirksamkeit. In der Praxis ist das häufig nicht möglich. Zudem ist der Wirkungsgrad bei hohem Befallsdruck nicht ausreichend. Der Einsatz von Naturalis-L liefert daher unter Praxisbedingungen häufig unbefriedigende Ergebnisse.

Rhagoletis cerasi: Oviposition reduction effects of oil products Organic Eprints
Daniel, Claudia.
The European cherry fruit fly, Rhagoletis cerasi (L.) (Diptera: Tephritidae), is a highly destructive pest. Methods to control it are limited and alternatives are needed.Observations of cherry fruit flies suggest that females exert much effort to penetrate cherries at color change stage (from green to yellow) for oviposition. Therefore, the question arose as to whether a physical barrier on the fruit surface could reduce oviposition. The effects of different commercial horticultural oil products on R. cerasi oviposition were evaluated in a series of laboratory, semi-field and field experiments. In the laboratory experiments, the rate of successful oviposition on fruits treated with 0.25% v/v of the rapeseed oil product Telmion was significantly reduced by...

Tag over æblerne - Er det vejen frem for usprøjtet æbledyrkning? Organic Eprints
Bertelsen , Marianne.
I økologisk æbledyrkning leder man efter muligheder for at bekæmpe sygdomme uden brug af sprøjtning. En mulig løsning i fremtiden er måske et lille tag over træerne.
