Monochamus impluviatus

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.

Panel on Quarantine Pests for Forestry (Vilnius, LT, 2002-03-12/14)

5. Pest Risk Analysis of individual pests

5.1.3 Monochamus impluviatus

The Panel did not develop a quantitative PRA for Monochamus impluviatus or for the other species considered in this meeting Mr Orlinski presented the datasheet on M. impluviatus, prepared by the EPPO Secretariat. Mr Karnkowski noted that this pest might be a vector for the pine wood nematode Bursaphelenchus xylophilus. Mr McNamara stressed that it would not be possible to qualify this pest as a quarantine pest because it is a vector of quarantine nematode, since this nematode does not occur in Russia. Mr Smirnov noted that Monochamus species are vectors not only of nematodes but also of different forest diseases. Mr Lindelöw wondered if there are some specific data on the damage caused by this species. Mr Orlinski answered that there exists two main opinions: some Russian scientists mention this species as one of most important pests of larch, pine and other conifers; other Russian scientists believe the importance of M. impluviatus is not very high. He believed that this is probably the result of different importance of the pest in different parts of its natural area. Most of the authors just mention the pest among other Monochamus species, noting only that it is the most cold-resistant and appears earlier in spring than other species. In conclusion, the Panel decided not to propose M. impluviatus as a quarantine pest for forestry.
