摘　　要：[目的]探索利用性诱剂防治主要危害烟叶的斜纹夜蛾、烟青虫、棉铃虫、小地老虎的诱捕器的最佳设置高度和筛选符合生产需求的诱捕器.[方法]在烤烟生长季节设置蛾类诱捕器、新型飞蛾诱捕器诱芯/进虫口与烟田墒面的垂直距离为70、110、150、190 cm 4个高度处理,调查诱蛾量.[结果]2种诱捕器诱蛾量最多的高度是70 ～ 150 cm,结合烤烟封顶后株高一般为1 m左右、诱芯/进虫口必须与作物顶部保持20 cm左右的特点,诱芯/进虫口初始高度应设置为120 cm.[结论]蛾类诱捕器具有购买成本相对低廉的优势,新型飞蛾诱捕器则有使用简单方便和管理成本低的特点.斜纹夜蛾优先选用蛾类诱捕器,烟青虫、棉铃虫首选新型飞蛾诱捕器,小地老虎可选用新型飞蛾诱捕器,也可选用专用蛾类诱捕器.云南烟区主要危害烟叶的4种夜蛾种群基数排列为斜纹夜蛾＞小地老虎＞棉铃虫＞烟青虫,但实际生产中对烟叶造成危害较大的是棉铃虫、烟青虫和小地老虎,所以生产中对4种夜蛾都应重视防治.[ Objective ] The aim was to explore optimal trapping settings height by using sex lures to control main pests like Spodoptera litura, Helicoverpa assulta, Helicoverpa armigera Hubner and Agrotis ypsilon in tobacco, and screen out the trapper which could meet the demand of production. [ Method] In the flue-cured tobacco growing season, heights that sex lures/insect-entrance of moth trapper and new moth trapper with the soil vertical distance of tobacco field had were set as 70, 110, 150 and 190 cm, and trapping quantity was investigated. [ Result] The height of maximum trapping moth quantity for two types of trappers was 70 - 150 cm. According to flue-cured tobacco stem height after topping was usually about 1 m, the distance of sex lures/insect-entrance and the top of crops must keep 20 cin, so the initial height of sex lures/insect- entrance should be set as 120 cm. [ Conclusion] Moth trapper has the advantage of purchase cost, while new moth trapper is simple to use convenient and has the characteristic of low management cost. Trapping S. litura should be optimizing moth trapper; trapping H. assulta and H. armigera should be optimizing new moth trapper; trapping A. ypsilon can choose new moth trapper, and also can choose special moth trap- per. The population base Of four main pests in Yunnan tobacco area is in order of S. litura 〉 A. ypsilon 〉 H. armigera 〉 H. assulta, but H. armigera, H. assulta and A. ypsilon have bigger harm in practical production, so people must pay attention to prevent and control the four kinds of moth in production.
