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.
