河南省烟草病毒病的介体蚜虫种类及与发病关系的研究

Preliminary Studies on Kinds of Vector Aphids of Tobacco Virus Diseases and Their Relation in Henan Province

在烟草栽培区，利用黄皿和绿皿共诱集传毒介体有翅蚜３２种，其中桃蚜Ｍｙｚｕｍｐｅｒｓｉｃａｅ（Ｓｕｌｚｅｒ）棉蚜ＡｐｈｉｓｇｏｓｙｐｉＧｌｏｖｅｒ分别占诱集蚜量的４７％和２３％。烟田类型不同病毒病发生程度不同，单作田和临菜田烟草病毒病发生严重，麦烟套种田较轻；５月迁入烟田的有翅蚜量与病毒病发生关系密切；提出防治烟草病毒病应通过早期防治病源地有翅蚜和麦烟套种等配套的措施，建立新的烟田农业生态体系。

species of vector aphids were trapped by yellow and green utensils in tobacco cultivated region.47% and 23% of which belonged to green peach aphid (Myzus ersicae (Sulzer)),cotton aphids (Aphis gossypii Glover),respectively.The amount of emigranting wing aphids and severity of tobacco virus diseases were different in different cultivated tobacco fields.The tobacco virus diseases were serious in pure tobacco fields and in the tobacco fields close to vegetable fields and weren't serious in interplanting fields of tobacco and wheat.The numbers of wing aphid in May had a significant effect on the outbreak of rivus diseases.The epidemic factors of viruses and countermeature were discussed.
