WU Hong-bo et al(The Tobacco Research of Guizhou,Guiyang,Guizhou 550003)  

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.
