A review of resistance breeding options targeting western corn rootworm (Diabrotica virgifera virgifera LeConte)

摘要

1 This review presents the latest research regarding maize resistance breeding against western corn rootworm (WCR) in the U.S.A. and Europe. 2 Investigations in Europe on the development of maize cultivars possessing resistant mechanisms against WCR are just beginning. In 2003, the European Commission implemented measures aimed at slowing down the spread of the WCR in Europe. Nevertheless, this pest has already been found in 20 countries of the European region. To establish a sustainable production system, the evaluation of native (nontransgenic) resistance in maize cultivars is essential. 3 This review emphasizes the future challenges involved in the research of native resistance breeding in maize against the insect.
