| 摘 要： | 对广州部分地区垂叶榕（Ficus benjamina Linn．）榕管蓟马（Gynaikothrips uzeliZimmermann）冷季种群动态及田间药效试验进行了研究．结果表明，冷季榕管蓟马种群的发生高峰为1月下旬，随后其种群数量迅速下降，在一个低水平的范围内波动，至4月上旬各虫态的数量慢慢恢复；榕管蓟马在垂叶榕东、南、西、北4个不同方位的虫口密度具有差异性，但对分布的方位没有明显的选择性；氯氰菊酯、氧化乐果、毒死蜱等3种药剂对榕管蓟马有很好的防治效果，药后3d的防治效果均达到95％以上．

| Abstract: | Population dynamic in cold season and field pesticide efficacy experiment of Gynaikothrips uzeli Zimmermann on Ficus benjamina Linn. were studied in some areas of Guangzhou. The results showed that the peak of this population in cold season was occurred in late January. After that, the population quantity declined rapidly and fluctuated in a low level scope, then recovered gradually until early April. |
