	abstract = {The efforts to stem the mass bark beetle outbreak in Austria did not defuse the situation. In 2006, bark beetle infested over 2.4 million m3 wood. This record level has now been maintained for four years. The consequence of the wind throw from gales 2007 and the climate of the last half year will not reduce the bark beetle situation. Seven Federal Provinces joined the Austrian Bark Beetle Monitoring. The results from 170 pheromone traps were presented on the bark beetle homepage of the BFW (www.borkenkaefer.at). In 2006, the flight activities in the Federal Provinces and over the various altitudes were almost uniform. In the case of Ips typographus, the flight period started between the beginning and middle of April and reached the maximum in mid-June. In comparing altitude classes, the flight period started later and lasted shorter in case of increasing altitudes. The wind throw from 2002 caused the heaviest damages in the Federal Provinces Salzburg and Styria. In 2006, the amount of bark beetle infested wood showed a different trend in these Federal Provinces. Therefore, the trap results were compared in order to see, if this trend is reflected in the monitoring data.},

Seven federal provinces joined the Austrian bark beetle monitoring system consisting of approximately 170 pheromone traps. The flight activity and especially the flight maxi-mum differed considerably. However, the flight showed a very consistent pattern starting early again, as expected.},

The development of a second generation should be temporally possible in many places. Therefore, with favorable weather conditions an intense and early flight can be expected in spring 2011.},

Significantly, more Ips typographus were caught with slit traps than with insecticide treated trap tipis. Both trap systems caught more beetles than common trap logs during the whole study (two periods: one month in spring and one month in summer). Slit traps brought evidence of similar trapping success in spring and summer insecticide treated trap tipis and trap logs were approached by 1. typographus more intensely in spring I. typographus were killed after coming in contact with the Pyrethroid sprayed bark surface of trap tipi log sections in both periods of investigation. Despite the presence of three attractive catching devices, infestation of standing trees by bark beetles (next to the test area) could not be avoided. The bark beetle predator, Thanasimus formicarius was found frequently on trap tipis and was also killed b) the insecticide coating.},

Trypodendron laeve Eggers was first found in Austria in 1982. Several further records connected with imported conifer timber from Russia led to the view that this species has been introduced to Central Europe and is not native here. Records from the Bavarian Alps, the Bavarian Forest National Park and the Sumava National Park now suggest that this is a widely distributed, native, but mostly unrecognized boreo-montane species.},

However, according to investigations on the species Gnathotrichus materiarius Fitch, Cyclorhipidion bodoanus Rtt., Xyleborus alni Niisima, Xyleborus germanus Blandf. and Taphrorychus villifrons Duf., these species may become a substantial threat to indigenous tree species. Their ecological impact cannot be totally assessed. At the moment, and based on our data, we consider Xyleborus germanus and Cyclorhipidion bodoanus to be the most dangerous species. In the deciduous forests of northern Bavaria, they are already the dominant bark-beetle species, penetrating increasingly into open landscape stands. The impact of these two introduced bark beetles on the autochthonous fauna and flora must be urgently investigated and pheromones for these species extricated for monitoring.},

In addition to the three most common types Xyloterus lineatus, Taphrorychus bicolor and Hylastes cunicularius also three species were represented which had been introduced from North America and Asia. The analysis of species distribution in the altitudinal gradient clearly shows that the sea level and inversely correlated annual average of the temperature explain most of the dispersion. Xyleborus germanus appears suitable as an indicator for change in temperature. Further attention should be paid especially to the future development of Phellinus viticola, one of the 18 harmful wood decay fungi},
