    Abstract : During 2010-2012 the research on the European corn borer (Ostrinia nubilalis Hbn) - a new corn pest for Belarus - was conducted for the first time. Its area was formed in the southern regions of the country (Gomel and Brest) where the sum of temperatures makes 2200-2600°C. In the central agroclimatic zone the European corn borer harmfulness did not exceed 18%. Focuses with high phytophage number and harmfulness were found in Brest and Gomel areas in which corn plants were damaged by 94% and grain losses made 45-60%. By the results of monitoring, the pest area expansion in the northern areas of Belarus is revealed, the quantity of high number focuses has increased. Studying corn protection measures against the European corn borer has shown that the agrotechnical methods reduced insects number and plant damage by 20%-46%., insecticides application during mass egg laying - beginning of caterpillars hatching reduced harmfulness by 76,9-98,7%, grain yield in these variants has raised by 1,62-3,79 t/ha. The obtained results can be used for biological substantiation of the integrated system of crop protection against Ostrinia nubilalis in Belarus.
