结果表明，从苗期鉴定、分集期蜜露量测定以及田间褐飞虱种群动态调查及产量测定的综合结果看出，应用分子标记辅助育种导入了Bph14和Bph15基因培育的新品系，即沪旱1A/07WH1462、川香29A/07WH644、川香29A/07WH1462、中9A/07WH1462、沪旱1A/07WH644和中9A/07WH644对褐飞虱均存在一定的抗虫性，前3种苗期表现为抗级，后3种苗期表现为中抗；主栽品种珞红3A/610234为感虫，主栽品种两优培九为高感。

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。

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 yellow boards play an important role in prevention and cure white fly in greenhouse because they can trap, stick and kill white fly. The test also shows that almost white fly often appear in the space where 5cm-15cm upper than the top of the plant. According to this result, the optimal hanging height of the yellow board should be at the place where 5cm-15cm upper than the top of the plant. The yellow boards should be set up as much as possible in this space to reach the best preventative effect.

同时使用黄板诱杀这一物理防治方法，也可有效减少温室内白粉虱数量，并且确定了植物顶端上方5~15cm处是白粉虱较活跃的区域，因此黄板应尽可能多的覆盖这一区域，以达到最好的防治效果。

The results are summarized as follows:(1) Observing and recording copulation events of whiteflies on plants using a video cameraA cost-effective,efficient,and reliable video recording system for observing and recording the mating behaviour of whitefly on live plants was developed.

结果如下：(1)使用摄像机观察和记录烟粉虱在活体植物上的交配行为研发了一套用于观察和记录烟粉虱在活体植物上交配行为的摄像系统，经验证该系统可以准确、连续地观察和记录该虫在较自然状态下的求偶和交配行为。

Based on Iwao's method, the formula of optimum theortical sampling number was established. By using methods for variance analysis, the number of B. tabaci eggs showed little difference on the upper, middle, and lower canopy of L.

应用Iwao的抽样模型，建立了烟粉虱卵的田间理论抽样数公式方差分析表明，烟粉虱卵在女贞树冠上层、中层、下层的分布数量差异不显著。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
