The pine wood nematode (Bursaphelenchus xylophilus), causal agent of pine wilt disease, is transmitted by longhorn beetles of the genus Monochamus (Col., Cerambycidae). Trapping vectors is one important measure for monitoring and control of pine wilt disease. Lures have been developed for M. galloprovincialis, the main vector in Europe. Flight behaviour of two potential vectors M. sartor and M. sutor was studied regarding pheromone, kairomone and weather influence. From July to August 2012, multiple funnel traps with three different combinations of attractants were installed in a mountainous spruce forest in Dürrenstein Wilderness Area, Lower Austria. Traps baited with the commercial lure Galloprotect 2D® (SEDQ, Spain), which consists of a Monochamus aggregation pheromone compound and two bark beetle pheromone components, caught lowest numbers of female and male M. sartor. Highest catch was attained by addition of the host tree volatile -pinene; the increase in males was statistically significant. Further addition of smoke volatiles did not enhance captures. Due to lower M. sutor catch, no significant differences in response to the lures were established. Catches of M. sartor and M. sutor were significantly correlated with weather factors mean and maximum air temperature. No flight occurred when mean temperatures fell below 15 C. Captured beetles were marked, released and recaptured to determine dispersal behaviour. Four M. sartor and five M. sutor of the total released 308 and 85 were recaptured. Within a mean time of seven days (maximum of 14 days), released beetles spread in all directions up to the most remote trap in 390 m distance, traversing spruce stands as well as open areas. This experiment gave first insight into flight activity of two potential pine wood nematode vectors in mountainous Austria, as well as into their reactions to traps and lures, developed for M. galloprovincialis.
