对玉米不同品种清种、混种和间种不同作物后玉米螟的发生情况进行了初步研究。通过玉米清种区与混种区的玉米螟发生情况比较、分析得出，混种对降低一代玉米螟卵量有明显作用，比清种一代玉米螟卵降低幅度在13%～45%。通过玉米间种不同作物后玉米螟发生情况分析得出，间种向日葵的小区中玉米螟的蛀孔数和活虫数明显低于其它处理，认为向日葵可能对玉米螟具有一定的驱避作用。

The occur of Asian corn borer(ACB), Ostrinia furnacalis(Guenee), had been studied in this paper after normal, mixed planting with different corns alternation planting with other corps. The study showed that the mixed planting with different corns could evidently decrease the number of one generation ACB eggs for comparison with the normal planting. The mixed planting could decrease the number of one generation ACB eggs about 13% - 45% than normal planting. Through the study on alternation planting with other corps, we found that the numbers of wormhole and live larvae in area of alternation planting with sunflowers were lower than with the other corps. So we confirmed sunflower had avoidance effect to ACB.
