摘　　要：对烟粉虱各虫态在番茄不同叶位层的分布调查结果显示,烟粉虱各虫态在番茄植株各部位均有分布,但分布极不均匀。卵、若虫主要集中分布在番茄的中部,而成虫主要集中分布在番茄的中部偏上。夏季番茄植株上调查烟粉虱卵、若虫和成虫的适宜叶位(由上往下)分别为第3~4叶、7~8叶和5~7叶,并建立了根据相关叶片上烟粉虱的数量估算整株虫量的数学模型。The distribution of adults, nymphs, and eggs of Bemisia tabaci on leaves of tomato plants was investigated in field in summer. The results showed that B. tabaci could be found in all the parts of the plant, but their densities were very different in the various parts. The eggs were mainly distributed in the plant＇s upper part, the nymphs in the middle part, and the adults in the upper middle part. The suitable sampling leaf was the 3rd and 4th leaves from the top for the eggs,the 7th and 8th leaves from the top for the nymphs,and the 5th^Tth leaves from the top for the adults. According to numbers of B. tabaci on the correlative leaves the models were established to estimate the number of B. tabaci in the whole plant
