The result showed that 83.1% of whitefly nymphs were present on top and middle leaves and there was no marked difference between middle and top leaves;significant difference was observed on the distribution of whitefly nymphs among different podding habit soybean varieties.

结果表明烟粉虱若虫在夏大豆植株上的总体分布集中在中上部，占总数的83.1%，中部与上部之间差异不显著。不同结荚习性大豆品种上烟粉虱若虫的分布存在明显差异。

The research activities were briefly highlighted as follows: They were yield nurseries, observational nurseries, tolerance/resistance screening nurseries (cold, drought, salt/acid, blast. bacterial leaf blight, rice tungro virus, brown planthopper and white-backed planthopper resistances). These studies with evolving technologies are aimed at improving crop production.

其研究活动着重于以下几方面：产量反应，生长观察，耐性/抗性筛选（抗冻、抗旱、抗盐/酸、抗稻瘟病、白叶枯病、水稻塘古罗病毒、褐稻虱和白背飞虱），其目的就是为了提高产量。

B. tabaci samples from 27 different areas, 14 provinces were collected, and the biotypes of the samples were identified by a RAPD-PCR method.

收集了国内14个省市25个地区的烟粉虱种群的样品，抽提到各个样品的DNA，并以DNA为模板，H〓为引物，对各个烟粉虱种群进行了RAPD-PCR分析和生物型鉴定。

The B biotype of Bemisia tabaci, sometimes called a "super bug", has been one of this species complex's most harmful biotypes because of the tremendous damage it inflicts worldwide.

B型烟粉虱是烟粉虱复合种下危害最为严重的一个生物型，现已成为一种世界性的害虫，被称为&超级害虫&。

The results showed that cotton was a suitable host plant for both biotypes,while kidneybean showed a significantly higher level of suitability to the ZHJ2 biotype than to the B biotype.

结果表明，棉花是两种生物型均适宜的寄主植物，而菜豆对ZHJ2型烟粉虱的适合性显著高于对B型烟粉虱的适合性。
