Rapid Pest Risk Analysis (PRA) for: Corythucha arcuata


This rapid PRA is an update of one produced in 2007 and shows that the oak lace bug has the potential to add strain to trees and ecosystems which are already under threat from other pests and environmental factors. This pest has been present in Europe for some time, but in recent years its distribution has either expanded, or its population levels have increased so there is greater evidence of the potential effects of this pest, though still many uncertainties. The ratings for establishment potential and economic impact remain unchanged, however, more evidence of the potential of this pest to move on wood and wood products has led to a raising of the risk of entry, and evidence from Europe suggests that this pest may have a greater potential environmental impact than previously rated.
