The Brassica pod midge Dasineura brassicae and its facilitator, the cabbage seed pod weevil Ceutorrhynchus obstrictus, have caused serious damage in oilseed rape crops during the last few years. No locally adapted IPM strategies exist, including pesticide management thresholds with evidentiary support. Management methods for the pod midge are in conflict with management recommendations for pollinators and natural enemies of oilseed rape pests. We develop an integrated crop protection strategy to handle these urgent problems: 1) monitor the relationships between abundances of pod midge and pod weevil, their phenology and damages, to identify critical levels and time window for damages. 2) Characterize the effects of specific treatment strategies at different developmental stages of oilseed rape, in combination with pest pressure, to develop evidence-based local decision thresholds, including suitable times for spraying.
