Forest Entomology

Our group Forest Entomology investigates forest insects in their broadest sense: ecology of potential forest pests, natural enemies, diversity of forest insects.

Research topics

  • Infestation dynamics of bark beetles, effect of natural enemies
  • Interactions between host trees and bark beetles
  • Recolonization of windthrow and wildfire areas by insect communities
  • Dependency of dead wood (saproxylic) insects on tree and stand characteristics

Call to participate in a global experiment

We propose a global protocol to assess human impacts on forest ecosystems using experimental microcosms. The main question we aim to address is:

How do current and future climatic conditions, forest habitat degradation and management, influence biodiversity and ecosystem functioning in water filled microcosms worldwide?

The field season has started!

In March, the insect traps for the Lothar projectwere installed so that early flying insects could also be detected.

The larch tortrix is back

Nearly 40 year after the last major outbreak of the larch tortix (Zeiraphera griseana) in the Upper Engadine, large-scale defoliation of larches due to the larvae of the larch tortrix could be observed this year. Beat Wermelinger reported in Swiss television (in German).
