| Organic fruit growers often suffer economic losses due to insect damages. The available natural pest control products are not always effective; and most important: many organic fruit growers would prefer not to use any pesticide at all. EcoOrchard, a CORE Organic Plus project (2015-18) aims to collect existing knowledge and generate new knowledge in order to use Functional AgroBiodiversity (FAB) successfully in orchards. This includes experimental trials in seven countries on the potential of inter-row flower strips for control of key pests and natural enemy augmentation, the establishment of the EBIO-Network as a European-wide network of stakeholders for collecting, sharing and improving scientific and practical knowledge and experience in FAB... |

| 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,... |

| Vegetable production systems are highly intensive and the periodic cultivations lead to un-favourable conditions for natural enemies. Using non-crops it is possible to create ecological infra-structure offering suitable food for natural enemies, and shelter from adverse conditions. On four organic farms in Western-Switzerland, we have tested in cabbage crops if wildflower strips are an appropriate tool to reduce lepidopteran pests. Analyses of wildflower strips on parasitism of caterpillars of Pieris rapae and Mamestra brassicae indicated a pest control potential. Grid trial using reared egg batches revealed no significant effect on parasitism of exposed M. brassicae and Plutella xylostella eggs in relation to the distance of the strip. |

| Im DOK-Versuch werden seit 1978 zwei biologische und zwei konventionelle Anbauverfahren sowie ein ungedüngtes Kontrollverfahren miteinander verglichen. Regenwurm-Erhebungen von 2001 bis 2005 haben gezeigt, dass sowohl bei der Biomasse wie bei der Anzahl Regenwürmer keine gesicherten Unterschiede zwischen den mit Mist und Gülle gedüngten Verfahren D2, O2 und K2 festzustellen sind. Dabei waren die Werte generell auf einem für Ackerböden hohen Niveau. Gegenüber früheren Erhebungen konnten mit dem Verzicht regenwurmtoxischer Pflanzenschutzmittel seit 1992 die Regenwürmer auch in den konventionellen Verfahren geschont und regeneriert werden. Das rein mineralisch gedüngte Verfahren M2 wies gegenüber den Hauptverfahren eine 13 % geringere Regenwurm-Biomasse auf,... |

| Fruit growers often suffer economic losses due to insect damages. The available natural pest control products are not always effective; and for organic fruit growers options for direct control are relatively few. EcoOrchard, a CORE Organic Plus project (2015-18) tracked EU farmers knowledge of Functional AgroBiodiversity (FAB) and generated new knowledge in order to successfully use FAB in orchards by a joint field experiment across seven countries of perennial flower strips to assess impact on natural enemies, codling moths and yield. The project also established the BIONetwork as a European-wide network of stakeholders for collecting, sharing and improving scientific and practical knowledge and experience in FAB management, and developed simple FAB... |

| Determining explanatory environmental factors that lead to patterns of biodiversity in cultivated landscapes is an important step for the assessment of the impact of landscape changes. In the context of an assessment of the effect of agricultural national extensification programme on biodiversity, field data of 2 regions were collected according to a stratified sampling method. A distribution model of 3 indicator species taxa (butterflies, spiders, and carabid beetles) is related to influencing factors by means of multivariate statistics (CCA, partial CCA). Hypothetical influencing factors are categorised as follows: (1) habitat (habitat type, management techniques) and (2) landscape (habitat heterogeneity, variability, diversity, proportion of natural and... |

| Der Einfluss von eingesäten Wildblumenstreifen (Buntbrachen) auf die Laufkäfer- und Spinnenfauna der ehemaligen Flachmoorlandschaft und heute intensiv bewirtschafteten Kulturlandschaft "Grosses Moos" (Schweizer Mittelland: Berner Seeland) wurde untersucht. Drei mit einheimischen Wild- und Kulturpflanzen eingesäte Wildblumenstreifen verschiedenen Alters sowie die angrenzenden Getreidekulturen in 15 m (Randbereich) und in 70 bis 100 m (Zentrumsbereich) Entfernung vom Wildblumenstreifen wurden mittels Trichterbodenfallen während 10 Fangwochen von Mai bis Juli 1999 beprobt. Von den 123 in 44.161 Individuen nachgewiesenen Laufkäfer- und Spinnenarten wurden insgesamt 110 in Wildblumenstreifen, 85 in den Randbereichen und 82 Arten in den Zentrumsbereichen... |

| Fazit Unter Einbezug der Erkenntnisse von Betriebspaarvergleichen und Parzellenexaktversuchen (Langzeit DOK-Versuch) kommen wir zur Schlussfolgerung, dass biologischer Anbau kombiniert mit qualitativ wertvollen naturnahen Flächen eine Schlüsselrolle für eine nachhaltige Förderung der Nutzarthropodenfauna in der ackerbaulich geprägten Kulturlandschaft darstellt. Regional ausgelegte Agrarumweltprogramme müssten so ausgerichtet sein, dass nicht nur ‚punktuell’ auf Betriebsebene sondern vermehrt auf der Landschaftsebene unter Berücksichtigung der Anbauintensitäten die Kulturlandschaft spezifisch aufgewertet wird. Dies würde zur Verbesserung verschiedener Umweltfunktionen (z.B. Biodiversität, natürliche Schädlingsregulation) wesentlich beitragen. |

| Intensive agriculture and excessive use of agrochemicals have resulted in an impoverished wildlife in agricultural landscapes, especially in arable landscapes but also in perennial high input crops. The elimination of semi-natural habitats, simplification of crop rotations as well as high input of fertilisers and pesticides is considered to be responsible for the severe decline of biological diversity that has been observed (e.g. Aebischer 1991). These practices can reduce habitat quality and remove the necessary habitat structure that is important to many natural enemies. Moreover, agricultural landscapes are increasingly being simplified; with natural and semi natural areas fragmented and replaced altogether by large monocultural fields. As a... |
