| 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“,... |

| Amara ovata und A. similata, zwei im Adultstadium phytophage Laufkäferarten, wiesen in Rapskulturen im Vergleich zu Winterweizenflächen und ökologischen Ausgleichsflächen (Buntbrache und extensiven Wieslandstreifen) in der Nähe von Basel ein mit TRichterfallen gemessene, hohe Aktivitätsdichte auf. Handfänge und Beobachtungen auf fünf anderen Rapsfeldern in der Umgebung von Basel zeigten, dass Amara ovata und A. similata Schoten, Samen und Blüten der Rapskultur fressen. Aufgrund der nahen Verwandtschaft des Rapses mit anderen Brassicaceen nehmen wir an, dass Raps für A. ovata und A. similata eine bevorzugte Nahrungsquelle darstellt. Ob dadurch ein wirtschaftlicher Schaden entsteht, ist zurzeit noch nicht klar. Ein stärkerer Befall ist in der Nähe von... |

| 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... |

| 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... |

| Burgeoning consumer interest in organically produced foods has made organic farming one of the fastest growing segments of agriculture. This growth has not been supported adequately by rigorous research to address challenges such as arthropod pest management. The research that has been conducted, however, is complemented by research in aspects of conventional agriculture that may have applicability in organic systems, as well as by research in underpinning fields such as applied ecology. This article synthesizes the available literature in relation to a conceptual model of arthropod pest management strategies suitable for organic systems. The present work uses the four phases of the model to review the strategies in an agroecological context and provides a... |

| 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... |

| 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... |

| 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. |

| Semi-field and field experiments were carried out to evaluate the biological control potential of entomopathogenic nematodes (EPNs) against grubs in hazelnut, chestnut and cherry orchards. Mortality of hazelnut weevils in interred containers treated with 2.2x106 infective juveniles (IJ) m-2 of Heterorhabditis bacteriophora was 75.4%. H. indica caused 65.2% and S. feltiae 43.3% pest mortality, but numbers were not significantly different from the untreated control (33.4%). Mortality of the chestnut weevil was slightly increased in S. carpocapsae (2x106 IJ m-2) treated containers (44.6%) compared to untreated control containers (39.2%), but differences were either not significant. Soil applications against the European cherry fruit fly did not lead to any... |

| Conservation and enhancement of biodiversity are mentioned in the International Federation of Organic Agriculture Movements (IFOAM) standards and in all national guidelines as essential pillars for organic agriculture. Recent reviews show that organic agriculture enhances the number of species and the abundance of many taxa (plants, birds, mammals, earthworms, arthropods, soil microbes), compared with conventional agriculture. Considering the benefits for sustainability, a multi-criteria analysis shows that organic agriculture not only improves biodiversity but also has positive effects on soil (e.g., soil erosion, structure, biological activity), water (e.g., no pesticide residues) and climatic factors (e.g., air pollution). In organic horticulture,... |
