山东烟蚜种群动态变异及其两种色型的消长规律研究

Studies on Variation of Myzus Persicae(Sulzer) Population and Dynamics of Two Color Forms in Tobacco Field of Shandong Province

20 0 0～ 2 0 0 1年对山东烟区烟蚜的种群动态进行了调查研究。结果表明其发生规律与 2 0世纪 80年代相比有了一定变化 ,5月份高峰期的蚜量增多 ,7月份高峰期的蚜量大幅下降或不能形成蚜量高峰。 5月份绿色型烟蚜的数量大于红色型 ,7～ 8月份则以红色型烟蚜为主。

The population dynamics of Myzus persicae (Sulzer) changed remarkably in tobacco field of Shandong province during 2000～2001 by contrast with it in 1980's Quantity of aphids in the first peak increased in May while in decreased the second peak in July or there was no second peak The proportion of green forms was higher than that of red forms in May The red forms were main population in July and August
