| 摘 要： | 调查表明,遵义烟区常见的烟草害虫种类有8目33科77种;天敌有6目14科25种,其中烟蚜、烟青虫、斜纹夜蛾和斑须蝽为主要害虫,烟蚜茧蜂是烟蚜的重要天敌,对控制烟蚜种群增长作用明显。研究表明,烟田生物群落的多样性指数越大,稳定性指数亦越大。6月下旬到7月中旬田间生物群落的多样性、稳定性指数均为最高,所以此时是抵抗外界干扰能力和恢复原状态的最佳时期,从而提高了对害虫的综合控制能力。

| Abstract: | The results indicated that there were 76 species of pests belonging to 31 familied,which threatened tobacco and 26 species of natural enemies belonging to 13 families in southwestern Guizhou,among which aphis cigarette,tobacco worm,meter worm and grouper to Chun meters were major pests.Smoke cigarette aphis cocoon bee was an important natural enemy to control tobacco aphis apparently.In tobacco field the greater biological diversity index was, the greater stability of the index was.In late of June to mid-July,the biome diversity and stability indexs were the highest in tobacco field,so it was the best periods for the original state to the restoration and the capacity to resist outside interference.Thereby,it can enhance the effect on the integrated pest management. |
