Description: Das Projekt "Wirkungen und Mechanismen von Bt-Transgenen Pflanzen auf die biologische Vielfalt von Nichtziel-Insekten: Bestaeuber, Pflanzenfresser und deren natuerliche Feinde" wird vom Umweltbundesamt gefördert und von Universität Göttingen, Institut für Pflanzenpathologie und Pflanzenschutz durchgeführt. The effects of transgenic, insect-resistant (Bt-) crops on biodiversity of non- target herbivorous insects and their natural enemies, and pollinators will be investigated. Four toxin/crop combinations will be used for testing effects of insecticidal proteins from Bacillus thuringiensis expressed in the crop plants on associated insects, on different organizational levels. Both in the laboratory and in limited field experiments, effects of transgenes on the biodiversity of the associated insect community will be studied. The mode of action of Bt toxin in a beneficial insect will be studied in more detail. Molecular tools consisting of cDNA microarrays will be developed for fast and efficient observation of effects, based on changes in gene expression patterns. The project will deliver contributions to a solid scientific foundation for EU policies and regulations for release of transgenic crops, and tools for monitoring effects on biodiversity.
