1 Whiteflies are major pests of many crops worldwide. Trialeurodes vaporariorum was introduced into the UK about 160 years ago. We aimed to understand their genetic diversity and population structure, and therewith their invasion history.2 Mitochondrial CO1 sequencing showed that T. vaporariorum had a low level of variation. Microsatellite analysis showed high diversity and indicated two, six and ten clusters, which were, to a limited extent, linked to locations, but not to host plants. The primary symbiont Portiera aleyrodidarum was detected in both sexes of T. vaporariorum, whereas only one secondary symbiont, Arsenophonus sp., was detected in almost all females, but not males.3 The population structure suggested that glasshouse agroecosystems restricted gene flow between glasshouse whitefly populations and that the movement of glasshouse whitefly was linked to human-assisted spread. 4 Taken together, the results suggested multiple, but limited numbers of introductions of T. vaporariorum mainly from countries nearest to UK.
