Overview of the evaluation of Takahashia japonica 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. First instar (crawlers) can be easily spread with the wind from the surroundings of the nurseries. The pest is extremely polyphagous. There are host species in the surroundings of the nurseries. An initial infestation of the pest could go undetected or confused with nymphs of other species 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 T. japonica between the years 1995 and December 2022 (EUROPHYT/TRACES‐NT, online). Shortcomings of current measures/procedures None. Main uncertainties – Pest abundance in the nursery and the surroundings. – The precision of surveillance and the application of pesticides used and other measures targeting the pest.
