为明确不同虫口密度下烟粉虱对番茄植株生长发育与生理生化指标的影响，以人工接虫的方法将定量烟粉虱接至9叶期番茄植株。结果表明：烟粉虱为害可明显抑制植株的生长发育；受侵害植株根系活力、光合速率、花粉活力、座果率和单果重等明显下降；植株体内叶绿素的合成与光合作用受阻，叶绿素含量和可溶性糖含量均明显下降；植株体内脯氨酸含量大量富集；可溶性蛋白质含量除在低接虫量植株体内有短暂上升外，其他植株体内可溶性蛋白含量均明显低于对照。

To detect the effects of Bemisia tabaci in different density on the development, and physi?ological and biochemical parameters of tomato plants, a certain amount of B. tabaci was inoculated to the 9th?leaf stage tomato plants. The results showed that the development of tomato was obviously in?hibited by B. tabaci, and root vigor, photosynthetic rate, pollen viability, fruit?setting rate and weight of simple fruit of damaged tomato were decreased significantly. Synthesis and photosynthesis of plant chlorophyll were inhibited, and chlorophyll content and soluble sugar of damaged tomato were lower than those of the control. However, proline content in damaged tomato was increased greatly, and soluble protein content in tomato damaged by a small amount of B. tabaci was elevated transiently while soluble protein content of other damaged tomato plants was obviously lower than that of the control.
