| 摘 要： | 本文报道了我国高纬度地区(黑龙江哈尔滨)烟粉虱和温室白粉虱的全年发生过程。连续2年调查结果显示,粉虱在哈尔滨地区只能在温室中越冬,于来年5月大棚的第一茬蔬菜上首先发生,至7月第二茬大棚作物时才在大田有少量(低于300头/百叶)出现,在7月末的部分保护地作物上,粉虱种群密度可达到6000头/百叶;而大棚蔬菜中则以番茄和黄瓜上发生最为严重,少量大棚因此绝收;入秋后又从大田消失。结果显示,我国高纬度省份的保护地(温室和大棚)粉虱为害仍然严重,迫切需要从切断源头和迁移扩散路线进行有效防治。

| Abstract: | The occurrence and development of Bemisia tabaci(Gennadius)and Trialeurodes vaporariorus(Westwood)was investigated in a high latitude area(Harbin,Heilongjiang Province)from 2008 to 2010.Under local climate conditions,whiteflies can only over-winter on greenhouse crops.They appeared on first-cut crops in greenhouses in May,then in fields when second-cut crops are planted in greenhouses in July and disappeared after autumn.Large whitefly densities were observed in several vegetable greenhouse fields at the en... |
