Sažetak
The corn is most dominant crop in Croatia and from 1992-1996 approximately 400 000 ha were cultivated every year, with corn seed production of 1.784.000 tones (4,49t/ha).
In Croatia, the European Corn Borer (Ostrinia nubilalis Hübner) is a major pest on corn, having two generation per year. The highest crop losses are due to the stem and ear attack. The average attack of 37,08% of ECB was determined during 25 years (1971-1996) in east part of Croatia.
Until 1985 attack of ECB was under 50% and from 1992 to 1996 it was 62,39%. Last few years, intensity of attack is very jigh and it is very difficult to find out tolerant hybrids for this pest. It was noticed, that FAO groups 300, 400, 500 and 600 are infected more than 50% by ECB. Averafe attack of ECB from 1992-1996 per FAO groups are following FAO 100 34,25%; FAO 200 45,83%; FAO 300 56,25%; FAO 400 66,01%; FAO 500 65,14%; FAO 600 71,76% and FAO 700 55,57%. Only agrotehnical measures are used in ourcountry to control ECB. In 1995, the trials were carried out with biological preparation Biobit XL and attack were reduced for 41%. This kind of measures should be continued in the future together with integrated pest management.
