Abstract


The project aims to develop a risk avoidance strategy targeting four principal, legume-specific insect pests in faba bean and field pea. Based on the analysis of empiric field data the effects of crop spacing and sowing date on pest incidence are explored in its potential for preventive cultivation planning. The project is embedded into an ongoing joint study (CYDNIGPRO; http://orgprints.org/29220/) addressing pea moth in field- and fresh peas. Here, the four partner institutions Uni-Kassel-FÖP, Gäa e.V., ZEPP Bad Kreuznach und LLG are covering additional key-pests, namely pea leaf weevil, broad bean– and pea weevil, as well as pea midge. Data sets from three distinct model regions concerning the infestation dynamics in space and in time, corresponding crop phenology as well as climatic data in three consecutive cropping cycles are augmented by climate chamber experiments to assess degree day estimates for the respective crop/herbivore interactions. Infestation/crop spacing correlations between previous and present fields are calculated employing GIS-tools as a) minmal distance (MD) and b) crop abundance index (CA-index) in graduated circles around actual legume sites. The derived situational risk avoidance strategy aims to support both organic- and integrated farmers in reducing direct control needs and to stabilize grain legume yields.
