Abstract

Latest research on biodiversity in agricultural landscapes suggests that flower visiting insects (FVI) such as wild bees and butterflies are not sufficiently protected from the effects of pesticides. To counteract this situation, the implementation of appropriate risk mitigation measures might be useful. Within the research and development project “Protection of wild pollinators in pesticide risk assessment and management” (FKZ: 3715 64 409 0; funded by the German Federal Environment Agency) recommendations for risk mitigation measures which might be suitable to protect FVIs were developed. Based on current available literature these measures were evaluated (1) according to their efficacy to reduce exposure of FVIs in off-field habitats by a reduction of pesticide entries in off-field non target areas, (2) according to their efficacy to reduce the exposure of FVIs in-field, and (3) according to their potential to reduce pesticide effects on populations of FVIs by the improvement of habitats (e.g. via providing foraging habitats). Moreover, acceptability and feasibility for implementation were characterized. Most important results for selected risk mitigation measures (e.g. in-field buffer strips) are presented in the poster.
