If introduced into Germany, Diabrotica virgifera would find maize in all regions of the country. Climatic conditions in winter would favour establishment. Though conditions in the growing season would be suboptimal, they would still be sufficient for development and completion of a full generation. D. virgifera has good potential for adaptation to different conditions and a high reproductive rate facilitating establishment in a new area. The type of maize grown would have no substantial effect on establishment of the pest. Crop rotation is important as a method for suppressing populations of the pests and restricting losses, but would not prevent establishment. Further containing factors (such as antagonists) are not available. So it can be concluded that D. virgifera is able to establish in Germany and could become an important maize pest.
