Institut für Pflanzenschutz in Obst- und Weinbau
The challenge for modern plant protection in fruit and viticulture is to strike a balance between crop management, fertilisation and plant protection on the one hand and nature conservation and resource conservation on the other.The present project develops urgently needed information on the influence of management measures on the biodiversity of insects in fruit-growing and viticulture through three complementary approaches: (A) Through a systematic investigation of vineyards and fruit crops with different management, the factors that limit insects are identified. (B) The Institute's own permanent observation plots will be established in order to be able to follow developments over time under known conditions as a basis for long-term monitoring. (C) Historical data on the occurrence of insects will be researched and made available as a reference for current stocks and their development. Which insects will be evaluated?The number of all captured insects on order-level is captured. Hymenoptera are examined more closely.Aculeate hymenopterans (bees, wasps, ants) are important predators and pollinators of cultivated and wild plants. Limited by food animals, flower supply but also by structural elements and therefore of high conservation interest.Terebrante hymenopterans (ichneumon wasps, proctotrupoid wasps, chalcid wasps) are important as natural opponents of pests and indifferent phytophagous insects.The locations are compared in space and time using multivariate methods.
