The codling moth, Cydia pomonellaL. (Lepidoptera, Tortricidae) is the key pest in apple growing worldwide. Its increasing resistance against various insecticides, including granulosevirus based plant products, initiate the search for supporting tools for natural control, e.g. the activity of parasitoids. The Chelonine species Ascogaster quadridentata, an egg-larval parasitoid, does not host-feed, but requires sustainable access to sugar resources for nutrition. In the framework of the European CoreOrganic Plus project EcoOrchard (http://coreorganicplus.org/researchprojects/ ecoorchard/)weestablished flowering strips in the rows between trees with the aim to support natural enemies. In adjacent laboratory tests we explored which kind of flowering plants and... |

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... |

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,... |

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... |

In many crops, the intensive use of pesticides causes major problems both for the environment and for natural ecosystem services. Apple is Europe's most frequently produced orchard fruit, requiring high pesticide input to combat the most important apple insect pests, Dysaphis plantaginea (Passerini) and Cydia pomonella (L.). Here we sought to control these pests by promoting natural enemies using sown perennial flower strips. We trialled these in the alleyways of organic apple orchards in seven European countries. Visual assessments over two years revealed a higher number of natural enemies on plant parts, and specifically in D. plantaginea colonies on trees, in flower strip plots than on trees in control plots with standard orchard vegetation. Trees in... |
