Forest pests and climate change
Abstract
To study the new type of outbreaks of the Spruce Mountain Sawfly, Pachynematus montanus, in lowlands of the foothills of the Alps and to estimate the risk for secondary attack by phloem feeding insects the following questions will be investigated: 1.) How does climate change influence the coincidence of swarming of the main dominant sawfly species (Pachynematus montanus, Pristiphora abietina and Pachynematus scutellatus) and shooting of spruce at different altitudes? 2.) Is there a change in the phenology of the Spruce Mountain Sawfly which might lead to an ousting of the so far dominant Small Spurce Sawfly, Pristiphora abietina, in the lowlands? 3.) What is the influence of natural enemies (esp. entomopathogenic fungis) on the regulation of the sawfly-populations in the study area and which methods in biocontrol may be used? 4.) Which extent of defoliation by the Spruce Mountain Sawfly may be of high-risk for subsequent bark beetle attack?
