For the first time, this study conducted a series of field sampling in multiple locations over several years and demonstrated that the B and Q biotypes first invade areas with high frequency of transport through human movement of plant materials, and then rapidly spread into surrounding areas and displace indigenous genotypes, and in parallel with displacement significant changes in sex ratio occurred in the mixed populations. Crossing experiments demonstrated that in the B. tabaci species complex there are many genetic groups that are completely or nearly completely isolated in reproduction. Apart from behavioural mechanisms, difference in host plant suitability and insecticide susceptibility between whitefly biotypes may also play important roles in the displacement of indigenous whiteflies by alien whiteflies in Zhejiang.
本研究首次以一个地理区域内广泛系统的野外调查数据证实,B型和Q型烟粉虱首先通过花卉苗木调运入侵交通较为发达的地区,然后迅速向周边扩张并取代土著烟粉虱,同时入侵取代过程伴随着混合种群中性比的变化;杂交试验证明烟粉虱复合种内存在多个生殖上隔离或基本隔离的遗传群;B型烟粉虱在浙江省内迅速取代土著烟粉虱,除行为机制外,生物型之间寄主适应性和药剂敏感性等方面的差异也可能在此过程中起着重要作用。
