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...

Aktivitäten im Bereich Obstbau-Entomologie 2002 Organic Eprints
Daniel, Claudia; Wyss, Eric.
Blattläuse im Steinobst: Die Grüne Zwetschgenblattlaus ist mit einer Austriebsspritzung Mineralöl / Pyrethrum gut bekämpfbar, während keines der geprüften Mittel eine befriedigende Wirkung gegen die Schwarze Kirschenblattlaus zeigte. Eine Zulassung von Neem als Nachblütebehandlung würde dieses Problem entschärfen. Die Wirkung von Spinosad („Audienz“) gegen den Apfelblütenstecher und den Pflaumenwickler: Spinosad zeigte in unseren Versuchen eine gute Wirkung gegen Apfelblütenstecher. Untersuchungen anderer Institutionen brachten jedoch gegenteilige Ergebnisse. Daher muss die Wirkung von Spinosad gegen den Apfelblütenstecher noch in weiteren Versuchen überprüft werden. Gegen den Pflaumenwickler konnte nur eine Teilwirkung von Spinosad („Audienz“,...

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.

Applications de soufre en automne: une nouvelle manière de lutter contre l`ériophyide à galles du poirier. Organic Eprints
Daniel, Claudia; Wyss, Eric; Linder, Christian.
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...

Approaches to pest management in organic agriculture: a case study in European apple orchards Organic Eprints
Wyss, Eric; Luka, Henryk; Pfiffner, Lukas; Schlatter, Christian; Gabriela, Uehlinger; Daniel, Claudia.
Although the European organic agriculture movement was founded by Rudolf Steiner and Hans Mueller in the years between 1924 and 1940, it was not until the 1980s that pest management researchers began to develop strategies to control pests in organic systems. Today, insect pest management in organic agriculture involves the adoption of scientificallybased and ecologically sound strategies as specified by international and national organic production standards. These include a ban on synthetic insecticides and, more recently, on genetically modified organisms (GMOs). The first phase of an insect pest management program for organic systems is the adoption of cultural practices including diverse crop rotation, enhancement of soil quality by incorporation of...

Ätherische Öle als Repellentien gegen den Rapsglanzkäfer (Meligethes spp.). Organic Eprints
Daniel, Claudia.
Essential oils can have an impact on pollen beetle (Meligethes spp.). Lavender oil (Lavendula angustifolia) showed the highest repellency value in a previous laboratory study (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 cubeba using a Y-tube-olfactometer. Essential oils were diluted 1:10 in...

Attaques en rase-mottes dans les cultures maraîchères biologiques suisses Organic Eprints
Wyss, Eric; Daniel, Claudia.
De nombreux ravageurs des légumes, comme p. ex. la mouche de la carotte, la mouche du chou ou la cécidomyie du chou, font vraiment du rase-mottes: ils se déplacent dans la végétation ou très bas au-dessus d’elle. Des filets verticaux, véritables clôtures anti-insectes, permettent de les stopper à leur entrée dans les cultures.

Aufbruchstimmung im Biokirschenanbau Organic Eprints
Häseli, Andreas; Weibel, Franco; Daniel, Claudia.
Die Produktion von Biotafelkirschen schöpft das Marktpotenzial lediglich zu 20 bis 25 Prozent aus, jene von Industriekirschen knapp zur Hälfte. Die Forschung hat in jüngster Zeit die Ertragssicherheit verbessert, die Marktpartner die Vermarktungsstrukturen. Das könnte den nötigen Schub für eine Ausdehnung der Anbauflächen geben, wobei sich eine Arbeitsteilung zwischen den Anbauformen abzeichnet: moderne Niederstammanlagen für Tafelkirschen, schüttelbare und widerstandsfähige Höchstammbäume für Industriekirschen.

Ausbreitung des Rapsglanzkäfers innerhalb eines Feldes und in der Landschaft Organic Eprints
Géneau, Céline; Schlatter, Christian; Daniel, Claudia.
Pollen beetles (Meligethes sp.) are important pests in oilseed rape (Brassica napus). In our study we wanted to determine which landscape structures have an influence on pollen beetle population in early spring. The dynamics of pollen beetle population and the damages on rape were studied on field scale level with 100 sampling points per field and on landscape scale level with 18 organic oilseed rape fields which differed by the complexity of the surrounding landscapes. The number of pollen beetle was strongly correlated with the distance to a forest. At the beginning of the flight period more pollen beetles were found close to the forest, later they migrated to the rest of the field. In addition, agricultural practices appeared to be determinant...

Autumn acaricide applications as a new strategy to control the pear leaf blister mite Eriophyes pyri Organic Eprints
Daniel, Claudia; Linder, Christian; Wyss, Eric.
The pear leaf blister mite Eriophyes pyri (Pagenstecher) causes severe damage to pear leaves and fruits. As mites are well sheltered from exposure to plant protection agents during summer and acaricide efficacy is reduced when temperatures are low in early spring, autumn acaricide applications were evaluated to control mites as they migrate to their hibernation sites. Post-harvest sulphur and mineral oil treatments were applied in September 2003 and mites were monitored in the following spring. Only the sulphur treated trees were virtually free of blisters. Sulphur treatments showed an efficacy of 95.3% (one application) to 99.6% (three applications), whereas, mineral oil treatments only had an efficacy of 12.8% (one application) to 69.6% (three...

Autumn applications of sulphur – a new approach to control the pear leaf blister mite Eriophyes pyri Organic Eprints
Daniel, Claudia; Linder, Christian; Wyss, Eric.
The pear leaf blister mite can cause severe damages to pear trees. By their hidden way of living inside the leaf blisters, the mites are protected from plant protection agents. Until now, oil treatments in early spring, when the mites leave their hibernation sites and invade the young leaves, are the only possibility to control these mites. Because of the low temperatures during this period (February/ March) the efficacy of pesticides is often not reliable. The aim of this study was to assess the effects of sulphur applied after harvest at the time, when mites are leaving the blisters and migrate to the hibernation sites. The treatments were applied shortly after harvest to benefit from the mild temperatures in September. Visual controls in...

Barrieren gegen die Kohldrehherzgallmücke Organic Eprints
Wyss, Eric; Daniel, Claudia.
Vertikale Netze haben Vorteile gegenüber Kulturschutznetzen: (1) sie liegen nicht auf der Kultur auf, (2) beeinflussen das Mikroklima kaum und (3) der Arbeitsaufwand, um die Netze für Durchfahrten (z.B. Hacken) zu öffnen, ist geringer. Die Ergebnisse müssen bestätigt, sowie die Anwendung auf weitere Schadorganismen (Möhrenfliege, Erdflöhe) ausgedehnt werden. Das Produkt «Audienz» weist, frühzeitig appliziert, eine genügende Wirkung gegen C. nasturtii auf.
