Sažetak
The resistance of sweet corn to the European Corn Borer is lower than in field corn. The chemical treatment by the insecticides should be done in the short period, from the attack of the Borer to the technical ripening of the cobs. This is particularly the case when it becomes necessary to repeat the treatment against the second generation of the Borer. The appearanc of the second generation is becoming more and more widespread in Vojvodina and Slavonija. The larvae attack manily the cobs. Cur investigation were carried out under artificial infestation of the plants in 1972 and 1973 in Zemun Polje. The results are obtained on the base of the data for 6 experimental hybrids and 8 inbreds, their parental components.
