| The effects of six fungus isolates on the mortality of different life stages of the European cherry fruit fly, Rhagoletis cerasi (Diptera: Tephritidae), were assessed in a series of laboratory experiments to find an isolate suitable for biological control. In a first step, the effects of fungus treatments on mortality, mycosis and fecundity of adult flies at a concentration of 107 conidia/ml were evaluated. All fungus isolates caused mycosis but virulence varied considerably among the isolates. Beauveria bassiana and Isaria fumosorosea caused 90–100% mortality and had the strongest influence on fecundity. Metarhizium anisopliae also induced high rates of mortality, while the pathogenicity of Isaria farinosa was low. The effects of lower conidia... |

| Application of processed kaolin particle film repels insects without lethal effects; hence side effects on beneficial arthropods are low. Processed kaolin may be an alternative to broad-spectrum insecticides used against European pear sucker, Cacopsylla pyri (L.), in organic and conventional pear production. Trials showed that the processed kaolin showed a very high efficacy, and the population of C. pyri was kept under a damaging level over the whole season. In conclusion, kaolin shows promise as an alternative control for C. pyri in organic and orchards of Integreted Pest Management. |

| The demand for cold-pressed organic rapeseed oil is increasing. However, the organic rape cultivation is challenging, especially various pests can cause problems. This leaflet provides some general information about the cultivation of rape. Different topics about rape varieties and their needs, the right crop rotation and weed management are covered. Additionally, the main part covers the various pests and provides strategies to control them. It is shown how the pests can be detected, and which preventive and direct are proven and permitted. Finally, there is also some information about economic aspects. This leaflet was made for farmers want to begin cultivating organic rape, but it might also be of use to conventional farmers. The information about... |

| Abstract: There has been a lot of emphasis over the years on the development and use of pesticides that are specific and/or physiologically selective. This is a property of the chemistry and mode of action of the pesticide and the physiological and biochemical attributes of organisms. However, there is also the potential to make pesticides more selective through their judicious use, based on critical selection, timing, dosage, placement and formulation of pesticides (which are often broad spectrum). This paper discusses approaches to increase the ecological selectivity of pesticides and pesticide application methods, in the context of Integrated Pest Management in Brassica crops. Topics covered include minimisation of the dose applied, controlled release... |

| Eng verwandt mit der Europäischen Kirschfruchtfliege Rhagoletis cerasi sind die beiden amerikanischen Kirschfruchtfliegen R. indifferens und R. cingulata Beide Arten sind morphologisch nicht zu unterscheiden (Foote, 1981). Ein Individuum dieser Artengruppe wurde erstmals in den 80er Jahren im Kanton Tessin in der Schweiz gefangen. Zwischen 1991 und 1993 wurde diese Art dann wiederholt im Süden des Kantons Tessin gefangen (Boller and Mani, 1994). Bisher sind keine grösseren Populationen dieser Art in der Schweiz bekannt (Boller, 2000), was jedoch möglicherweise auf eine zu wenig intensive Überwachung zurückzuführen ist. Ein intensives Überwachungsprogramm im Rheintal (Rheinhessen, Deutschland) konnte zwischen 2002 und 2004 nachweisen, dass diese Art weit... |

| Mit Hilfe der kantonalen Fachstellen für Weinbau wurden 2015 und 2016 gegen 250’000 Traubenbeeren in über 600 Parzellen auf Eier der Kirschessigfl iege (KEF, Drosophila suzukii ) überprüft. Die Datenauswertung zeigt, dass die Anfälligkeit der Trauben mit der Beerenreife steigt, dass insbesondere die roten Rebsorten Acolon, Cabernet Dorsa, Cornalin, Divico, Dornfelder, Dunkelfelder, Galotta, Garanoir, Humagne rouge, Mara, Regent und Syrah stärker gefährdet sind und dass weichhäutige Rebsorten vermehrt befallen werden. |

| In organic agriculture, treatments with rock dusts for soil amendment, disease prevention, or insect control have a long tradition. Clinoptilolite (a naturally occurring zeolite) was tested against pollen beetle Meligethes spp. in organic and IPM oilseed rape fields in order to find a control strategy compatible with the guidelines for organic and IPM agriculture in Switzerland. Dust and spray applications were evaluated in several large-scale field trials from 2008 to 2011. Dust applications using 300-750 kg/ha pulverized Clinoptilolite (particle size < 0.1 mm; product Klinofeed, available from Unipoint, Switzerland) were applied using a drop-box fertilizer spreader or a Vicon pendulum spreader. For spray applications the same Clinoptilolite (product... |
