Neotoxoptera formosana

Extracts of reports of EPPO Meetings

As mentioned on the introductory section of the Web page on PRA documents, PRA documents are working documents which have usually been produced by an assessor whose opinion may have been commented during Panel meetings and comments have usually not been included in the PRA documents but are found in Panel meeting reports. This document consists of extracts of EPPO Meetings' discussions on Pest Risk Analysis documents on the relevant pest. Discussions on Pest Specific Phytosanitary Requirements (PSPR)[1], have also been reported when relevant as they include elements on possible risk management options.

34th Meeting of the Panel on Phytosanitary Measures (Paris, 2002-01-22/25)

6.  EPPO Alert List: annual review

6.2  Candidates for EPPO A1/A2 lists supported by newly prepared PRAs

Neotoxoptera formosana

The Panel was presented with a CSL PRA prepared by Mr McLeod (GB). Mr Bartlett explained that concerns arose because this pest, attacking mainly onion and garlic, had been found and eradicated in UK in 1999. There had also been outbreaks in Italy and the Netherlands, and the pest had been detected in imported consignments on several occasions. Mrs Zioni wondered about the host status of ornamental Allium spp. Mr McNamara noted that the data presented gave clear evidence that this pest could move in trade, establish and cause damage. He suggested that countries should reflect further on this pest, which would be studied again at the next meeting.

Neotoxoptera formosana should remain on the Alert List and will be studied again at the last meeting. If appropriate, the British PRA should be revised.

7.  Candidates for the EPPO lists

7.11 Already considered at the last meeting

Neotoxoptera formosana. No new information on these pests had been provided to the EPPO Secretariat, which had not circulated the old documents. Mr Finelli reported on the Italian outbreak, which had been found approximately 25 km from Verona in the municipality of Oppiano, in one farm specialized in the production of leaf vegetables (chives). The pest had been found in some (but not all) glasshouses of the farm. The infested plants had been planted already for three years and the source of infestation was not known. N. formosana had not been found in weeds around glasshouses. Trapping had been conducted on other farms in the area, but the pest had not been found. The pest had so far not caused severe damage on the farm concerned. Eradication measures were still being applied.

This pest will be studied at the next meeting. Further elements on PRA might be provided by UK if necessary.

36th meeting of the Panel on Phytosanitary Measures (Paris, EPPO headquarters, 2004-03-9/12)

8. Candidate Pests for EPPO listing

·  Neotoxoptera formosana. The United Kingdom suggested that Neotoxoptera formosana could be added to the EPPO Alert List in 2000-04. This pest had been found in 1999-09 on a stock of Welsh onions (A. fistulosum) and the infested tubs were destroyed. Mrs Petter (Chairman) explained that no new information had been received on this pest since the last meeting. Mr Bartlett informed the Panel that one flying aphid was caught in a suction trap in UK, and one specimen was detected in 2003-12 on fresh onions imported from France. Mr Gonzalez thought that N. formosana did not qualify as a quarantine pest because the pest had been introduced into France but no economic damage has been recorded.

Additional information and comments on the PRA prepared by UK would be provided by France.

37th meeting of the Panel on Phytosanitary Measures (Paris, 2005-03-08/11)

8. Candidate Pests for EPPO listing

8.2  Review of pest risk assessments

·  Neotoxoptera formosana. A PRA was prepared by the British NPPO after the pest was found on a stock of Welsh onions in 1999. Mrs Petter (Chairman) reported that the French expert commented that this insect has been present in France for 10 years but is still rare. It was also recorded from Finland, Netherlands, UK and Italy but its presence and damage were considered to be of minor importance. Messrs Horn and Finelli agreed.

On the basis of the PRA, Neotoxoptera formosana will be deleted from the Alert list.
