The results showed that the invasive B biotype has the capacity to displace the non-B biotype in a short period of time.

这说明B型烟粉虱具有在短期内竞争取代浙江非B型烟粉虱的能力。

Liu and his colleagues suggest that the presence of the native whiteflies causes biotype B flies to mate more often.

刘博士及其同事的研究结果显示，本地粉虱的出现能够致使B型粉虱更为频繁地交配。

During the processes of invasion and displacement,the B biotype has caused considerable damage to a range of crops.

近20年来，B型烟粉虱Bemisia tabaci广泛入侵世界各地，并在一些入侵地取代了危害不严重的土著烟粉虱，对生产造成了巨大的危害，而且入侵区域还在不断扩大。

Extensive field data showed that the B biotype has gradually displaced some indigenous biotypes of this species complex in many regions of invasion.

大量的野外调查表明，在许多入侵地，B型烟粉虱在入侵过程中逐渐取代了土著烟粉虱。

Another Three Species of Lernanthropus de Blainville, 1822 Parasitic on Marine Fishes of Taiwan, with a Key to the Species of the Genus Lernanthropus Found in Taiwan

并列篇名寄生在台湾海水鱼上属於人形鱼虱科的另三种人形鱼虱属(Lernanthropus de Blainville， 1822)桡足类，并对在台湾所发现属於此属的种类做－检索表

Bioassaying of squash silverleaf assigned the whitefly from Beijing (host: cotton and sweetpotato) and Xinjiang to B biotype. However, populations from Fujian and Guangxi without silverleaf symptom were considered as non-B biotype.

银叶生测实验表明：北京甘薯、棉花和新疆茄子上的烟粉虱为害西葫芦后可引起寄主的银叶，表明属B型烟粉虱；福建甘薯和广西南瓜上的烟粉虱种群在西葫芦上为害不呈银叶属非B型。

Microscope examination showed that whitefly occurred in Beijing was B. tabaci rather than T. vaporariorium by vasiform orifice characters of the fourth instars.

根据北京重发区粉虱的形态特征，表明该粉虱应属烟粉虱，主要的鉴别特征是它们的四龄若虫腹背瓶形孔构造。

The sensitive nymph instar and sexual differences of wing dimorphism in the brown planthopper, Nilaparvata lugens , were studied, and the developmental differentiations of both the indirect flight muscles and the wing buds in the brown planthopper were observed. Molecular biological studies were performed to amplify the indirect flight muscle specific actin gene.

本文研究了褐飞虱Nilaparvata lugens翅型分化的若虫敏感临界龄期和翅型分化在性别上的差异，观察了褐飞虱间接飞行肌和翅芽发育的分化过程，在此基础上，以扩增、克隆褐飞虱间接飞行肌特异性肌动蛋白基因为目的，做了部分分子生物学工作。

The transmission electron microscopy was employes. The psyllids were able to transmit Las to their host plants 7 days after acquisition from the Las-infected plant.

为了解黄龙病菌在柑橘木虱体内的活动过程及对木虱之可能影响，应用穿透式电子显微镜观察黄龙病菌在柑橘木虱体内的循环过程。

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。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
