This project focused on the control of grubs (larvae of the brown chafer Serica brunnea) in the cultivation of Syringa and leatherjackets (larve of crane flies; Tipulidae) in the cultivation of Campanula. The main objective was to develop a framework for integrated management of these soil pests, for which the timing of possible management measures throughout the year fit the climatic conditions, the development stage of the pest and the cropping practices. First a framework was made for both crop-pest combinations in which the timing of possible (non-chemical) intervention was indicated. Subsequently, several of these possible interventions were tested. For the monitoring of adult S. brunnea beetles a funnel trap with alcohol as an attractant was shown to be a good alternative for a light trap. Soil predatory mites could be stimulated in both Campanula and Syringa fields with the addition of yeast. In the laboratory a moderate effect of two species of soil predatory mites and a predatory beetle could be observed on young leatherjackers. None of the tested soil predators could control the eggs of the crane flies. Whether soil predators can contribute to the control of leatherjackets in the field could not be tested due to low pest pressure. CO2-alginate capsules, which have been shown to attract several species of soil pests, among which wireworms and western corn rootworm larvae, could not attract leatherjackets and S. brunnea grubs.
