摘要
通过2003～2005年对北京地区西花蓟马发生为害情况进行的系统调查监测,发现发生地由2003年的2个点扩大为2005年的6个区,呈蔓延扩散趋势;为害的植物也从最初的辣椒到2005年的28科65种,以葫芦科的荷兰黄瓜、甜瓜及十字花科的白萝卜叶片受害最为严重。另外,就不同寄主上西花蓟马的发生为害动态进行了系统调查,初步分析了其在自然条件下的种群消长规律。
Systemic surveillances were conducted to monitor the occurrence and damages of western flower thrips in Beijing. It was revealed that the numbers of incidence spots increased from 2 districts in 2003 to 6 districts in 2005; the range of host plants of western flower thrips spread from hot popper in 2003 to 65 species of plants belonging to 28 familia, in which Holand cucumber, melon and white radish were the most seriously infested crops. In addition, population dynamics of western flower thrips and their damages to different hosts were preliminary discovered through systemic surveillances.
