| 1. Ants provide ecosystem services to agriculture by controlling arthropod pests. Plant diseases, however, can be more detrimental to plant production than herbivory. Here, we investigate a new type of potential ant service – namely that ant hygiene may extend beyond the ants themselves to also cover their host plants, potentially resulting in protection against plant diseases. 2. We review the literature for support to the idea that ant hygiene, including ant-derived antibiotics, can protect plants against pathogens, and we provide empirical pilot data from a Danish apple plantation further supporting this idea. 3. In a literature search, we found nine studies showing ants reducing pathogen incidence on host plants. These studies cover nine ant species... |

| Zielsetzung des beantragten Projektes ist die Bewertung der ökosystemaren Leistung natürlich vorkommender Gegenspieler (Parasitoide, Viren, Bakterien, Pilze) des Apfelwicklers in wichtigen Apfelanbauregionen Deutschlands (Altes Land, Kraichgau, Bodensee). Neben dem regionalen Vorkommen sollen auch saisonales Auftreten und ökologische Interaktionen dieser Organismen untersucht sowie potentielle Nebenwirkungen unverzichtbarer Pflanzenschutzmittel im Kernobstanbau auf die Leistung der Antagonisten geprüft werden. Darauf aufbauend werden Strategien für ihre achhaltige Erhaltung und Förderung entwickelt.Das Forschungsvorhaben besitzt zwei miteinander eng verknüpfte Aktionsbereiche: Teilprojekt A: "Invertebrate Nützlinge" (Leitung Dr. Annette Herz) und... |

| Orchards, as intensive cropping systems, often have low diversity of plant species, which limits the promotion of natural enemies for pest control. The implementation of agri-environmental schemes, such as flower strips, could enhance biological control. We developed perennial, multifunctional flower strips with native plant species. In the second and third year after sowing, plant diversity and ground cover between flower strips (FS) in the drive alleys and the spontaneous orchard vegetation in control plots (Cont) were compared in 19 experimental blocks of eight organic apple orchards in six European countries. On average 73.7% of the sown plant species were established and plant diversity of FS was on average 43% higher than in Cont. Multivariate... |

| L'objectif de ce projet était de comparer la facilité de gestion et à l'efficacité à favoriser la biodiversité fonctionnelle de deux mélanges d'espèces florales, l'un dit sauvage, l'autre dit cultivé, en verger commercial. L'expérience s'est déroulée à Victoriaville et à Frelighsburg, où un premier semis a été effectué au printemps 2012. L'établissement des mélanges étant très faible à Victoriaville en 2012 dû à un envahissement majeur par les mauvaises herbes, un deuxième semis a été réalisé au printemps 2013 sur la moitié des parcelles. La floraison et l'établissement des mélanges de plantes ont été suivis, ainsi que les populations et les dégâts de carpocapses de la pomme (Cydia pomonella) dans les parcelles avec bandes florales ainsi que dans des... |

| Ants can function efficiently as biocontrol agents in open field horticulture. Temperate wood ants can control forest pests, including species damaging forest regeneration plots and fruit plantations. Thus, they possess potential as biocontrol agents in open field horticulture, if they can persist in these systems. Here we present observations on activity and survival of wood ants transplanted from forests into different types of plantations. Mound fragments were transplanted into a conifer seedling plot, an organic and a conventional Christmas tree plantation, and into an organic apple plantation. Colonies survived at least one year in all types of plantations. In some cases, however, ants moved to new locations or migrated between mound fragments,... |

| Perennial flower strips improve the effectiveness of biological pest control by predators and parasitoids in fruit production. The guide presents results from the European EcoOrchard project and other studies, explains how the flower strips function, introduces suitable plants and describes step by step the procedure for planting and maintenance. The information is supplemented by information on the costs and possible disadvantages of the flowering strips. |
