Research

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.

Research-Projects:

1. The impact of plant colonizing soil microrganisms on the invasion success of the maize pest Diabrotica virgifera virgifera

2. Risk assessment of the development of resistance traits of the invasive Western corn rootworm (Diabrotica virgifera virgifera) against Bt-corn due to the use of alternative host plants

3. Resistance-screening of german maize varieties against the invasive western corn rootworm und identification of possible resisteance factors

4. Threat to European maize production by the invasive quarantine pest, Western Corn Rootworm (Diabrotica virgifera virgifera): a new sustainable crop management approach (DIABROTICA)
