摘要
根据１９９５年和１９９７年烟田系统调查资料，得出烟蚜Ｍｙｚｕｓｐｅｒｓｉｃａｅ（Ｓｕｌｚｅｒ）的种群数量动态呈双峰曲线，第一高峰消长阶段烟蚜茧蜂ＡｐｈｉｄｉｕｓｇｉｆｕｅｎｓｉｓＡｓｈｍｅａｄ和食蚜绒螨Ａｌｏｔｈｒｏｍｂｉｕｍｓｐ．以及第二高峰消长阶段龟纹瓢虫Ｐｒｏｐｙｌａｅａｊａｐｏｎｉｃａ（Ｔｈｕｎｂｅｒｇ）、中华草蛉ＣｈｒｙｓｏｐａｓｉｎｉｃａＴｊｅｄｅｒ和大灰食蚜蝇ＭｅｔａｓｙｐｒｈｕｓｃｏｒｏｌａｅＦａｂｒｉｃｉｕｓ数量波动趋势与烟蚜同步。相关分析、Ｆｕｚｚｙ聚类分析和通径分析表明：影响烟田烟蚜种群数量变化的天敌分为：草间小黑蛛Ｅｒｉｇｏｎｉｄｉｕｍｇｒａｍｉｎｉｃｏｌｕｍ、烟蚜茧蜂和食蚜绒螨以及中华草蛉、龟纹瓢虫、大灰食蚜蝇和小花蝽ＱｒｉｕｓｍｉｎｕｔｕｓＬ．三个功能类群，其中烟蚜茧蜂与中华草蛉和龟纹瓢虫分别是控制烟蚜第一、第二高峰消长阶段种群数量增长的优势种群。
The results of systematic field investigations in 1995 and 1997 showed that the population of M.persicae (Sulzer) gave a two-peak type dynamic curve.The population dynamics of Aphidius gifuensis Ashmead and Allothrombium sp.was accorded with that of M.persicae (Sulzer) at the first peak and so were Chrysopa sinica Tjeder,Propylaea japonica (Thunburg) and Metasyprhus corollae Fabricius' at the second peak.The results of correlation,fuzzy aggregation and path analysis indicated that the natural enemies affecting the population dynamics of M.persiae (Sulzer) in tobacco field might be classified into three types of fuctional group.e g.<Erigonidium graminicolum (Sundevall)>,<A.gifuensis Ashmead and Allothrombium sp.>and<C.sinica Tjede,P.japonica (Thungerg),S.corollae Fabricius and Orius similis Zheng>.A.gifuensis Ashmead was the dominant population of natural enemies to control M.persicae (Sulzer) at the first peak of M.persicae's population,while C.sinica Tjeder and P.japonica (Thungerg) at the second peak.
