Main topic of my studies are the relationships between the leafbeetle Western Corn Rootworm (Diabrotica virgifera virgifera LeConte, Galerucinae, Chrysomelidae) and its host plants. This maize pest species has been introduced into Europe in the beginning of the 90s and is steadily spreading ever since. The new ecological setting in Europe requires intensive studies on both adults and larvae. Within an EU-research-project the adult beetles were studied regarding the use of alternative pollen resources found inside or along maize fields. The larvae which are mainly responsible for the economic damage are studied regarding host plant preference and its implications for IPM strategies. Several European maize cultivars and Bt-maize are tested regarding their suitability for WCR larval development. Furthermore monocot weeds and other crops like winter wheat are tested with regard to their potential to act as alternative hosts for the larvae.
