Abstract: 【Objective】 Ostrinia furnacalis is the main pest on corn. The relationship between Ostrinia furnacalis occurrence and crop distribution was studied in the hope of providing a theoretical basis for ecological prevention and control of the pest. 【Methods】 In the typical occurrence area of Ostrinia furnacalis in Shule County, the effect of crop distribution experiment was conducted in which the amount of moth, eggs dropping amount, larvae, alfalfa and the index of decay rate of stem, the number of holes on stalks and cluster and living insects were used to evaluate the population dynamics and damage of Ostrinia furnacalis under maize+cotton (Tr1), maize+melon (Tr2) and maize+wheat (Tr3) intercrop patterns. 【Results】 In terms of population dynamics, there were some differences in the amount of trapped moths, dropped eggs, larvae and alfalfa under different crop distribution (P < 0.005). The amount of moth (overwintering, 1st and 2nd generations), eggs, larvae and alfalfa of Tr1 adjacent field were significantly higher than those of Tr2 and Tr3 (P < 0.005); Moreover, the amount of dropped moths, dropped eggs, larvae and alfalfa in the Tr2 adjacent field were higher than those in the Tr3, while the difference was not significant (P > 0.005); In terms of hazard: There were some differences in the occurrence and damage of Ostrinia furnacalis (P < 0.005) under different crop distribution; In addition, the average rate of corn stalk rate was 18.03% and the difference was significant (P < 0.005), and the total number of holes and living insects from large to small was Tr1>Tr3>Tr2 and Tr1>Tr2>Tr3. 【Conclusion】 After emergence of overwinting adults of the Ostrinia furnacalis, they preferred to migrate to the Tr1 neighboring field and the 1st and 2nd generation adults preferred the field of corn planting around the cotton. Above all, occurrence and damage of the Ostrinia furnacalis could be regulated by crop distribution and rational chemical control.
