Abstract
The western corn rootworm Diabrotica virgifera virgifera has invaded large parts of the maize growing areas of Central Europe since it was first detected in 1992 near Belgrade, Serbia (eDWarDS et al., 2011). In 2002 the beetle arrived in the eastern parts of Austria and extended in 2012 into the southern and western parts. Only a few cases with observed economic damages have been recorded since in those areas. Official control measures according to EU Decision 2003/766/EG are in place to prevent the further spread of the western corn rootworm. Crop rotation as the most efficient strategy to suppress the western corn rootworm should be applied either alone or in combination with insecticide treatments. In our study we aimed to test the effects of Styrian oil pumpkin rotated with maize on the reproduction of Diabrotica in isolation cages in the field.
