- Summary
This update report is a follow-up of an earlier report of October 2014 concerning the first finding of this thrips in Europe. Following the first report a specific survey was completed at nine other growers of Hydrangea. The thrips was also detected at four other growers, including outdoor conditions and other non-cultivated plants (weeds). A preliminary risk analysis has been completed indicating that the pest can survive outdoor conditions in the Netherlands. Based on the great number of affected plants at individual growers, introduction must have taken place several years ago. Wider establishment in the Netherlands is presumed based on earlier sales of affected plants to the final consumer and the soil-borne nature of certain life stages of the pests. Therefore no further measures are taken against this pest. The origin of the finding is unknown but may be linked to imports of cuttings from Japan. The organism is not listed as a harmful organism in the EU directive 2000/29/EC and is not listed on the EPPO A1 or A2 list. The organism is known to occur in Japan and South Korea (see http://www.padil.gov.au/pests-and-diseases/pest/main/136443). The organism acts as a vector for Tomato spotted wilt virus.
