Organic Chemistry

Ecological chemistry is a research area studying the structure and function of chemical signals between organisms. Our aim is to investigate the molecular receptive range (chemodiversity) in insects, the specificity and complexity in perception, behaviour, learning and speciation, i.e. the chemical basis of biodiversity. Main interests are the chemistry and biochemistry underlying insect behaviour with focus on insect/insect and insect/host plant interactions.

Our results are utilized for example in environmentally safe antifeedants for the large pine weevil, use of pheromones and kairomones for the control of insect pests and repellents for ticks and mosquitoes. In the last 5 years more than 50 papers in international scientific journals, and in 9 PhD theses. For recent results see:
