1·The results indicated that all 8 populations were of the biotype B.

综合上述结果，说明福建省8个烟粉虱种群均属于生物型“B”。

2·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。

3·Why that should be true only for this particular biotype is unknown. Finding the answer would make a lot of farmers happier.

但是，为什么只有这种特殊的生物型出现了该种情况还不得而知，因此，解答这一难题将使千千万万的农民受益.

4·Phylogenetic analysis of primary endosymbionts based on 16S rDNA indicates that the non-B biotype is native to China while the B biotype is an invasive biotype.

初生共生细菌的系统发育分析表明，B型是入侵生物型，而浙江非B型是本地生物型。

5·curly shoot virus and tomato yellow leaf curl virus. These predatethe arrival of biotype B, but the new arrival does particularly well on plants infected by them.

在中国，烟粉虱传播烟草曲茎病毒和番茄黄曲叶病毒，这些病毒在B生物型入侵前便有之，但新的生物型在感染该等病毒的植株上活得尤为“有滋有味”。

6·On the hand, the germplasm conserving and collection both protect the vital representative resources and avoid the resources are reduce and repeat in the genetic biotype.

对种质资源搜集和保存一方面保护了重要的有代表性的材料，减少或避免基因的流失和资源材料的重复。

7·A mutated “biotype B” insect emerged in Napa Valley in 1980 and did an estimated $6 billion of damage before wide-scale uprooting, burning and replanting was completed in 1995.

1980年，加州纳帕谷出现了一种基因突变的“同型小种B型”蚜虫。 这种蚜虫造成了估计60亿美元的损失，随后葡萄园开始了大规模连根拔除，烧毁并重新栽种于1995年完成。

8·The genetic distances among different biotypes were significantly higher than within the same biotype, while Q biotype showed the least genetic distance of 0.9% within itself.

进化分歧数据还表明， 不同生物型之间的遗传距离明显大于同一生物型内遗传距离， 其中Q型内部差异最小， 在0.9%以内；

9·The results showed that:(1)the specific amplified patterns using the primer H16 could distinguish biotype B populations from biotype Q populations and non-B/Q biotype population in Zhejiang province;

结果表明：（1）引物H16对烟粉虱B型不同种群扩增的特异带，能有效区分烟粉虱B型和Q型、浙江非B/Q型种群；
