Studies conducted in the years 2005–2010 showed that maize plants (Zea mays L.) in the south-eastern part of Poland are damaged by a large number of harmful insects. In addition to the insect species occurring on maize for many years, the presence of new species, not recorded yet was also stated in the studied region. The conducted studies confirmed that maize is an attractive source of food for many harmful organisms, including those ones causing no serious damage to maize plants, and thus not directly affecting the yield.
