Crop-damaging wireworms are the soil-dwelling larvae of click beetles. Wireworms have emerged in Europe over the last 15 years. There is actually few efficient control solutions, and actual control options use toxic pesticides. There is therefore a need for safer control techniques. A survey of 341 maize fields by Saussure et al. shows that wireworm damage is decreased by the occurrence of hedges and cultivated crops at the maize field border. Whereas wireworm damage is increased by the occurrence of grassland at the maize field border or during the rotation.
