This blue-black beetle with red pronotum is a major crop pest in Europe, Asia, and parts of north Africa. The beetle is controlled by using a number of parasitoids as biological control include the parasitic wasps Diaparsis carinifer, Lemophagus curtus, and Tetrastichus julis, which attack larvae, and Anaphes flavipes, which is an egg parasitoid, and ladybirds eat the eggs and larvae.
