| 摘 要： | 观察、研究了烟粉虱在温室甘薯寄主上全年的种群发生动态和在甘薯寄主上的空间分布特性.结果表明:烟粉虱在福州地区温室甘薯寄主上全年可发生10代,世代重叠严重,冬季越冬不明显,7-12月为主要发生危害期.烟粉虱在寄主植物上具有垂直分布特性,且分布在叶背的虫量明显多于叶面.

| Abstract: | The population dynamics and space distribution charac ters of sweetpotato witefly, Bemisia tabaci (Gennadius) on the sweetpotato host in greenhouse in Fuzhou , were observed and studied. The results were as follows: swee tpotato whitefly had 10 generations per year with generations overlapping grea tly; its hibernation was not obvious; the main period of damage in a year was f rom July to December; it had perpendicular distribution characters on the h ost p lant, and the population density in the back of leaf was higher obviously than that in the front of leaf. |
