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；

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；
