StartClim2011.A: Influence of Climatic Conditions on Voltinism and Dispersal of Ips typographus in the Alpine Zone
Abstract
The proposed study will be carried out in a cirque of the Dürrenstein Wilderness area and comprises three topics: 1. In a retrospective analysis of data about the infestation intensity of the bark beetle Ips typographus for the period 2003-2010, the spatio-temporal impact of weather, stand, and development conditions on the dispersal of the beetle will be checked. 2. Pheromone traps will be concentrically placed at different distances around an actual infestation zone in order to recapture marked bark beetles which are released from this zone. With this method we want to investigate the preferred dispersal route and the distance of the beetle’s flight activity depending on environmental conditions (weather, terrain, forest stands). Furthermore, the question should be answered whether crests of special elevation are natural dispersal barriers for I. typographus. 3. Results from this study are used to develop scenarios for spreading of bark beetle outbreaks in the study area under climate change conditions of +2°C und +4°C.
