Applied Arthropod Ecology

The research group studies ecological interactions among arthropods and plants in managed and semi-natural ecosystems. It includes effects of crop and plant diversity on herbivores and their natural enemies, monitoring of organisms, and impact of management practices on functional biodiversity of insects and other fauna - from population to landscape level.

Our goal is to contribute to the development of sustainable use of natural resources, which facilitate adaptation to changes in management practices, land-use and climate. We focus on monitoring and management strategies in production systems, with emphasis on preventive and direct measures of biological control. It encompasses methods that characterise the complex interactions of organisms in ecosystems by field experiments, insect observations, laboratory bioassays, and molecular methods.


  • Functional biodiversity in managed and natural ecosystems
  • The biology and ecology of insect pests and their natural enemies in agroecosystems
  • Monitoring of organisms
