| 摘 要： | 在河南棉区，第１代玉米螟在棉田为害严重，第２、３代很少为害棉花。不同类型田相比麦棉套种田受害较重。采用频次比较，聚集度指标判别等方法对棉田玉米螟的空间分布型进行了探讨。结果表明，麦棉套田螟卵块呈均分布，其余田块玉米螟卵、幼虫均属聚集分布。 |

| Abstract: | Severe damage of 1st generation and little of 2nd and 3rd generations of Asian corn borer(ACB)Ostrinia furnacalis Guenee to cotton in Henan cotton area.Wheat interplanted with cotton suffered more heavy damage when compared with different cropping systems associated with cotton.The spatial distribution pattern of ACB was studied using the methods of the discrete frequency distribution test and judging by indices of aggregation and so on.The results on the distribution patterns showed that egg masses of corn borer in wheat intercropping with cotton fields were of uniform patterns,the others were of aggregated patterns.According to the investigation results,the integrated management tactics and technical mesure, determined as taking agricultural mesures as the dominant factor. |
