一、与地形的关系麦穗夜蛾在察右中旗广大麦田中虽均有分布,但主要分布在西南山地丘陵区的金盆、乌兰、七苏木、大滩、二号地、头号、蒙古寺等七个公社的山谷盆地。呼市郊区、武川县、四子王旗、卓资县的麦穗夜蛾猖獗区,因这些盆地四周均围有高山、丘陵高地作为自然屏障,因而形成相对风小、冷暖变化不激烈,比较湿润的地方性小气候,有利于麦穗夜蛾栖息越冬,故而成为麦穗夜蛾的猖獗区。这种地形与呼市郊区、武川县、四子王旗、卓资县的麦穗夜蛾猖獗区基本相似。
First, the relationship with the terrain of wheat Spodoptera in Chazhongzhongqi Although the vast majority of wheat fields are distributed, but mainly distributed in the southwestern hilly area of Jinpen, Ulan, Seven Hematoxylin, Beach, No. 2, the number one , Mongolian temples and other communes valley basin. The outskirts of Hohhot, Wuchuan County, Siziwangqi, Zhuozi County of the rampant wheat spider moth, surrounded by these basins are surrounded by mountains, hilly highlands as a natural barrier, and thus the formation of a relatively small wind, warm and cold changes are not intense, more humid place Sexual microclimate is conducive to the winter moth habitat overwintering, it has become a rampant area of the wheat thorn moth. This terrain and the outskirts of Hohhot, Wuchuan County, Siziwangqi, Zhuozi County of the Spider mite rampant area is similar.
