为了更好地了解入侵地区的菜豆花叶病毒流行病的病因，我们需要了解土著和入侵性粉虱载体如何对病毒感染作出反应。我们调查了番茄黄化曲叶病毒（TYLCV）感染对烟粉虱入侵Q生物型和土著亚洲ZHJ2生物型烟粉虱的直接和间接影响。Q生物型在未感染或病毒感染的番茄植株上的表现优于ZHJ2生物型。然而，病毒感染的宿主植物没有，或只有轻微的影响，表现的任一生物型粉虱的繁殖力，寿命，生存，发展和人口增长。同样地，与TYLCV的载体的关联不影响Q或ZHJ 2生物型在棉花（TYLCV的非宿主）上的繁殖力和寿命。这些结果表明，外来Q型粉虱可能成为TYLCV在田间的主要传播媒介，并促进病毒的流行。
To better understand the etiology of begomovirus epidemics in regions under invasion we need to know how indigenous and invasive whitefly vectors respond to virus infection. We investigated both direct and indirect effects of infection with Tomato yellow leaf curl virus (TYLCV) on the performance of the invasive Q biotype and the indigenous Asian ZHJ2 biotype of whitefly Bemisia tabaci. The Q biotype performed better than the ZHJ2 biotype on either uninfected or virus-infected tomato plants. However, virus-infection of host plants did not, or only marginally affected, the performance of either biotype of whiteflies in terms of fecundity, longevity, survival, development and population increase. Likewise, association of the vectors with TYLCV did not affect fecundity and longevity of the Q or ZHJ2 biotypes on cotton, a non-host of TYLCV. These results indicate that the alien Q biotype whitefly, but not the indigenous ZHJ2 biotype, is likely to become the major vector of TYLCV in the field and facilitate virus epidemics.
