Significance of the European corn borer (Ostrinia nubilalis Hübn.) in maize production

The European corn borer (Ostrinia nubilalis Hübn.), which is to be found almost universally in Europe and America, is an extremely important pest from the economic point of view. Losses caused by the pest range from 250-1000 kg/ha depending on the degree of infestation, the year and the yield averages. This fact justifies protection measures in Hungary on the whole of the seed production and sweetcorn fields and on 40% of the commercial maize sowing area. In addition to the direct damage, indirect losses are also considerable, since the injuries caused by the pest facilitate infection by Fusarium species. For the above reasons it is worth reviewing the habits of this pest, the extent of the economic loss resulting from the damage, and ways of controlling it.
