Welcome to Insect Chemical Ecology, Ethology and Evolution - or IC-E3 for short!

Chemical ecology is the study of how organisms perceive their surroundings through chemical senses, and the
adaptations that enable them to function in a specific chemosensory context. Our work is in an interdisciplinary
field of research. It incorporates aspects of ecology and evolutionary biology, ethology, neurobiology, physiology,
insect systematics and morphology, molecular biology, analytical chemistry, biochemistry, biomimetric engineering
and pest control.

Our goal

We want to understand how insects adapt olfactory-mediated behavior to a changing environment by phenotypic and geno-typic modulation, from individual adaptation to evolutionary change.

The knowledge of behaviorally active chemicals and their per-ception can be brought to application as safe and powerful tools to control and monitor insect populations.

In order to reach the goal we study the modulation of the insect response to chemical signals at physiological, behavioural and ecological time scales. Methods range from molecular biology to landscape scale manipulation of behaviour.
