The Food & Environment Research Agency (FERA) found the pest on plants during a four-week period from mid-February to mid April.
The infestations included Ocimum basilicum (Sweet Basil) imported from the Canary found in London; Hibiscus in parcels from the United States detected at the Coventry Parcels Depot; on Hemigraphis colorata (Red Flame Ivy) from Singapore found at Heathrow Airport; on Alternanthera from Singapore identified at Manchester Airport and on Bacopa from Singapore detected at Heathrow Airport.
FERA is currently consulting with growers on the future of the UK's protected zone status against Bemisia tabaci.
The UK is one of a limited number of EU member states including Finland, Ireland and Sweden that maintain protected zone status against the pest, which is particularly damaging to salad crops such as cucumber and tomato.
