亚洲玉米螟在河北省张家口海拔1400 m以下地区均有分布。800 m以下地区是种群的主要分布区,以 500～600 m虫口密度最大。800 m以上发生程度一般很轻,其中个别地区因局部气候适宜,发生程度较为严重。同一海拔梯度内,水浇地与盆地的种群数量显著高于丘陵和旱地。不同寄主田内种群的分布比率,在海拔 800 m以下地区,玉米田高于谷子和高粱田,900 m以上地区谷子田明显高于玉米田。
Asian corn borer in Zhangjiakou, Hebei Province, altitude below 1400 m are distributed. The population below 800 m is the main distribution area of the population, with the highest density of 500 ~ 600 m. Occurrences above 800 m are generally very light, of which some areas are more severe due to the suitable local climate. Within the same altitude gradient, the population of irrigated fields and basins is significantly higher than that of hills and drylands. The distribution ratio of population in different host fields was higher in maize fields than in millet and sorghum fields at altitudes below 800 m, and in maize fields above 900 m was significantly higher than that in maize fields.
