烟

A light sentence; a light accent; casualties were light; light snow was falling; light misty rain; light smoke from the chimney.

轻微的处罚；轻微的口音；人员的伤亡很少；下着小雪；如烟的微雨；那个烟囱冒出的轻烟。

The variety of quartz include crystal, iris or color quartz, titanic spot or crispite quartz, amethys, citrine, smoky quartz, furong stone, dongling stone, dumortrierite quartz, milky quartz, siderite or sapphire quartz, tiger's eye, hawk's eye, quartz cat's eye, starlight quartz.

石英的种类包括（水晶、晕彩或彩红石英、金红石斑点或网金红石石英、紫晶、黄晶、烟石英或烟晶、芙蓉石、东陵石、蓝线石石英、乳石英、蓝石英或蓝宝石石英、虎眼石、鹰眼或猎鹰眼、石英猫眼、带星的或星光石英）。

In addition to the direct transmission between plant and whitefly, geminiviruses can also be transmitted through mating and oviposition among whiteflies.

双生病毒除了在植物与粉虱之间直接传播外，还可通过烟粉虱交配及经卵携带的途径在烟粉虱个体和代别间进行传播。

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。

What geminiviruses that can be acquired by whitefly and the possibility for virus transmission are affected by the host plants, the special protein of geminiviruses as well as the GroEL proteins synthesized by endosymbionts of the vector.

寄主植物、双生病毒的一些特殊蛋白以及烟粉虱内共生菌产生的QroEL蛋白，都可影响烟粉虱携带的双生病毒种类及传毒的可能性。

These results indicated that a significant mutualism developed between TYLCCNV and the Q biotype whitefly but not so obvious between TYLCCNV and the ZHJ2 biotype whitefly.

这表明，TYLCCNV与Q型烟粉虱之间能够产生显著的互惠关系，而与ZHJ2型烟粉虱之间的互惠关系则不显著。

Minimum time required for acquisition and inoculation of geminiviruses by the whitefly is 15-30 min Geminiviruses may be retained in their vector for one to several weeks, and sometimes for the entire life of the vector.

烟粉虱最短的获毒和接种时间为15~30min；双生病毒在烟粉虱体内可存留1至数周，有的终身存在。

The results are summarized as follows:From 2004 to 2008, field investigation was conducted in 19 locations which differ in terms of frequency of transport activities in Zhejiang, 11652 whitefly individuals collected from 154 plots were analyzed by RAPD PCR and mtCO1 sequencing to determine their genotypes. The results revealed the presence of at least 5 genotypes of B. tabaci in Zhejiang, and each genotype has its own distribution.

主要研究结果如下：2004年至2008年，本研究在浙江省内对按交通发达程度选择的19个有代表性的地点进行了连续5年的田间调查，通过RAPD-PCR和线粒体CO1测序方法对154个样块中11652头烟粉虱进行生物型鉴定，结果显示，浙江省内至少存在5个烟粉虱遗传型，且具有各自特定的分布区域。

The fluctuation of whitefly on poinsettia was studied by investigated the number of whitefly during different stages of growth period of poinsettia. The optimization comprehensive measures were studied by comparing the control effect on whitefly during different stages by different methods.

方法］调查&一品红&不同生育生长期内烟粉虱的数量，研究其消长；比较不同处理在不同时期对烟粉虱的防治效果，研究优化综合防治措施。

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。
