The project I am currently working on focuses on the ecology and preventive management of the turnip sawfly (Athalia rosae L.). My work combines chemical ecology, agricultural plant science and entomology. The project is funded by the Kone Foundation and I collaborate with the Natural Research Institute Finland and the University of Eastern Finland.
