Detection of pinewood nematode in Portugal has increased the threat to the EU from this extremely dangerous pest. The key objective for this project is to develop an improved Pest Risk Analysis methodology that can be used at both local and regional scales to assess the significance of a plant health threat and, by use of a core model, to assess the consequences of outbreaks. Seven research institutes of six nations cooperate within this project, which is funded by the European Union. Within this project the Austrian team is in charge of vector survey and vector biology and the development of early detection methods. Vector survey in Austria was carried out by using pheromone-, wood-log traps and traps with burned wood material. No Monochamus beetles were caught by the different traps. The studies of the Monochamus biology showed, that the beetles make a maturation feeding during there whole life with a peak during the first two weeks. Under laboratory conditions Monochamus galloprovincialis pistor beetles stayed alive for 53-94 days. Female beetles died 1 - 2 weeks earlier than male beetles. Three different methods (bioacoustics, electrical conductivity and measurement of resin flow) were tested for early detection of effected trees. So far, best results were achieved by measurement of resin flow.
