The results showed as followed :（ 1 ） The most important factor of atmospheric general circulation controlled and influenced the immigration of WBPH＇s populations was the patterns and the tempo-spatial changes of potential height field on 850hPa isobaric surface,（2） There were relative coincident air streams with a northern exposure on 850hPa isobaric surface during the migrations northward of WBPH and there were concurrent airflows with a southern exposure on 925hPa isobaric surface during the migration southward.

Precocene could induce macropter, the more macropterous adult were found the higher titer of preconece was applied to the larvae, and the macropter inducement was more effective at the 3rd instar than at the 4th instar, the macropterous adults rates were 100% or 86.67% respectively when S. furcifera were treated by 10μg/μl or 100ng/μl preconece at the 3rd instar.

早熟素具有明显的长翅化效应，随着处理浓度的增高，被处理的白背飞虱若虫形成的长翅型成虫数也逐渐增加，且早熟素在3龄期处理对白背飞虱长翅诱导作用强于在4龄期进行的处理，如在3龄期处理时，10μg/μl和100ng/μl的处理组长翅型成虫比率分别高达100%和86.67%。

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。
