摘  要：
调查花椰菜、甘蓝、番茄、黄瓜4种寄主植物上烟粉虱的发生动态。结果表明,烟粉虱的卵-若虫数量在寄主植物的生育期内持续增长,10月1日达到高峰,之后逐渐减少,其发生动态在4种寄主间及同种寄主不同部位叶片间有差异。烟粉虱卵-若虫在4种寄主上虫口数量依次为番茄>黄瓜>花椰菜>甘蓝。烟粉虱卵多集中分布在4种寄主上中部叶片,且上部多于中部,上部与下部间差异显著;若虫多集中分布在4种寄主中下部叶片,中下部间无显著差异,上部叶片基本无分布。烟粉虱成虫发生量与日平均温度呈正相关,与日降雨量呈负相关。

摘  要：
In this paper,the dynamics of Bemisia tabaci(Gennadius)on four host plants(e.g.cauliflower,cabbage,cucumber and tomato)were investigated.Our results showed that the number of eggs and nymphae of B.tabaci increased with the growth of host plants continually and peaked at 1th October,then it decreased gradually.However,the dynamics were different among the hosts and leaf sections.The number of eggs and nymphae of B.tabaci on the four hosts was tomato>cucumber>cauliflower>cabbage.In addition,eggs of B.tabaci were mainly on the upper and middle leaves,but the number on the upper was more and the difference between on the upper and bottom was significant.In the contrast,the nymphae were mainly on the middle and bottom leaves,but there was not significant on the upper and bottom.In the end,the adult densities were positively correlated with the daily mean temperature,but negatively correlated with the daily rainfall.
