Overview of the evaluation of Bemisia tabaci (European populations) for bundles of whips and seedlings
Rating of the likelihood of pest freedom	Pest free with some exceptional cases (based on the Median).

Summary of the information used for the evaluation	Possibility that the pest could become associated with the commodity The pest is present in the UK, with few occurrences but continuously intercepted. The UK outbreaks of B. tabaci have been restricted to greenhouses. The pest is extremely polyphagous. Other traded plants present in the surroundings of the nursery could be a source of the pest. Polytunnels and glasshouses in the nurseries could act as a reservoir of the pest. The pest could go undetected during inspections. Measures taken against the pest and their efficacy General measures taken by the nurseries are effective against the pest. These measures include (a) inspections, surveillance, monitoring, sampling and laboratory testing; (b) hygiene measures; (c) application of pest control products and (d) removal of infested plant material. Interception records In the EUROPHYT/TRACES‐NT database, there are no records of notification of Acer plants for planting neither from the UK nor from other countries due to the presence of B. tabaci between the years 1995 and December 2022 (EUROPHYT/TRACES‐NT, online). There were four interceptions of B. tabaci from the UK in 2007 and 2015 on other plants already planted likely produced under protected conditions (EUROPHYT, online) Shortcomings of current measures/procedures None. Main uncertainties – Possibility of development of the pest outside greenhouses. – Pest abundance in the nursery and the surroundings. – The precision of surveillance and the application of measures targeting the pest. – Host suitability of Acer spp. to the pest.
