Sažetak
European corn borer (Ostrinia nubilalis Hübner) is a very important economice pest on corn in northerneast part of Croatia. The intensity attack is very high but its control is very poor.
In Slavonia region, appearance of Europan corn borer on corn was being investigated from 1985 to 1995. Every year about 50 hybrids of corn, FAO groups 100 to 700 were investigated. The dissection of plant was done during the autumn prior the harvest. Measured factors were a foffows: number of hols, number of caterpillars and their position in esr, above the ear, and below the ear, per plant.
All hybrids are attacked by this pest every year, and the highest intensity was at FAO groups 400,500, and 600. The lowest was 17,05% and the highest was 98,4% (average 56,61%) The highest number of holes and caterpilllars was below the ear (43,30%, 61,62%) above the ear (28,91%, 26,26%) and in the ear (25,78%,12,12%).
Only agrotttecnical measurs are provided among integrated pest management. The last few yearss we tried to control European corn borer by biological insecticides on the base of Bacillus thurgiensnsis Berliner. The attack has been reduced from 9 to 42%. The investigation is very important and indicates the possibilities of biological control as one measure of integrated pest management in corn production.
