In order to determine the dates of the treatments, it was necessary to catch adult flies. The researchers used yellow 25 x 40 cm sticky traps placed on three control plots to catch the adults. Monitoring of cereal leaf miners flights in winter wheat was carried out in Babor6wko （greater Poland voivodeship）. Yellow traps were placed above the tops of wheat during vegetation period. The number of damaged wheat stems was recorded. Fluctuations in weather conditions during the research affected the dynamics of leaf miner flies considerably. The maximum flights of leaf miner flies on winter wheat crops in years of the studies took place in May. The dynamics of leaf miners flights were different in growing season 2008 and 2009. The most common species were： Chromatomyia nigra （Ztt.）, Chromatomyia fuscula （Ztt.） and Poemyza superciliosa （Ztt.）. It was also discovered that the species composition of Agromyzidae damaging the winter wheat, changes in particular years.
