New finding of Scirtothrips dorsalis in the Netherlands
In the Netherlands, Scirtothrips dorsalis (Thysanoptera: Thripidae – EPPO A2 List) was first found in 2019 in a nursery on Podocarpus plants for planting imported from China (EPPO RS 2019/182) and declared eradicated in July 2022 (RS 2022/204). In October 2022, S. dorsalis was found again during a regular inspection on Podocarpus macrophyllus in a greenhouse.
Official measures were applied and include a crop treatment schedule of 5 weeks in the infested production site followed by a monitoring survey with sticky traps to ensure that the treatment was successful. The movement of plants from the infested site is prohibited for 7-8 weeks.
