Einfluss verschiedener Wirtspflanzen auf den Adultschlupf des westlichen Maiswurzelbohrers Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae) und Parameter der adulten Käfer

Since the late 60s it is known that larvae of the Western Corn Rootworm (WCR) Diabrotica virgifera virgifera LeConte 1868 (Coleoptera, Chrysomelidae) do not only feed on maize. Already in the late 60s and early 70s nearly twenty possible monocotyledonous host plants for the larvae of WCR were recorded, but nearly all field data known were gained in the United States. For Europe only laboratory or greenhouse data are available. For this reason field trials were carried out in Lovrin, Romania, since 2004. Five different weeds, mainly Setaria-species were identified and considered to be suitable host plants for the larvae of WCR under Romanian field conditions.
