摘要
为镇远烟区建立有效的蚜虫预防机制及其统防统治提供参考,通过采用棋盘式10点取样法、黄皿诱蚜法及5点取样法调查,对2014—2015年镇远县烟区早春蚜虫虫源基数、有翅蚜迁飞、田间烟蚜与天敌和蚜传病毒病(PVY+CMV)的发生规律及危害情况进行研究。结果表明:在当地越冬寄主中,油菜上的蚜虫总量最多,2年平均达18.44头/株;有翅蚜的迁飞呈双峰型,无翅蚜种群动态为单峰型,且发生高峰为5—6月。建议大田防治在5月中旬至6月上旬进行。
The Myzus persicae base and occurrence regularity of migration of winged aphid,M.persicae and natural enemy,and damage condition of aphid-transmitted virus（PVY＋CMV）were studied by 10-point checkerboard sampling,yellow vessel and 5-point sampling methods to provide a reference for the efficient prevention mechanism and integrated control of M.persicae in Zhenyuan tobacco cultivation region.Results：Total M.persicae number in rape plants is the maximum in local overwintering hosts and the mean value is 18.44/plant.The migration of winged aphids shows a bimodal pattern.The population dynamics of wingless aphids presents a unimodal pattern and the occurrence peak is in May and June,which indicates that M.persicae control in tobacco fields should be conducted from the middle ten days of May to the first ten days of June.
