摘要
斑须蝽是一种世界性害虫,分布广,寄主种类较多,笔者于1987-1990年在江苏南京江浦、龙潭,苏北的新沂、盱眙地区进行了生物学及其防治的系统研究,表明此虫在长江流域中下游,苏南地区年发生4代,在苏北烟区年发生3代,均以成虫越冬.运用有效积温法则推算基本相符.烟田发生的种群动态与气温,湿度和栖息环境密切相关.第二、三代为害春烟和夏烟,已成为江苏烟草生产上一种重要害虫.
Dolycoris baccarum(Linnaeus)(Hemiptera:Pentatomidae)is a worldwide in- sect pest,which has great range of hosts in the world.It has become an important pest of to- bacco in Jiangsu,Henan,Shandong,Jiangsi,Zhejiang and Helongjiang provinces recently. Studies on the bionomics were carried out in Jiangpu and Longtan of Nanjing during 1987-1990.The pest has 4 generations each year in middle-low area along Yangzhi River and South Jiangsu,while it has 3 generations in North Jiangsu.It overwinters in adult stage.Pop- ulation dynamics is affected by temperature, humidity and crop rotation.The second and third generations damage the spring and summer tobacco greatly.
