Göran Nordlander
Göran Nordlander is Emeritus Professor of Entomology at the Department of Ecology. His research mainly concerns the ecology and behaviour of the pine weevil (Hylobius abietis), and how damage on confer plants by this insect can be counteracted. Another research interest is systematics of parasitic wasps (Cynipoidea).


My research activities principally fall within three different areas:

- ecology, behaviour, and pest management of the pine weevil Hylobius abietis
- conservation biology and dispersal of insects living in wood-decaying fungi
- taxonomy, phylogeny and biogeography of parasitic Hymenoptera (Cynipoidea)

 A long-lasting goal has been to find ecologically sustainable ways of reducing damage on conifer plants caused by the pine weevil, Hylobius abietis, to economically acceptable levels. Research focus is on how the weevil's behaviour is affected by environmental factors and how weevil feeding on seedlings can be reduced by applying various silvicultural measures. Another focal area is the plant´s own defence against insect feeding, both induced plant defence and the significance of inherited plant properties. In cooperation with microbiologists and chemists I have also studied the roles of fungi and bacteria associated with the pine weevil for chemical communication and metabolism.

Within my research group we have made a number of innovations with the aim to protect conifer plants from insect damage by the use of coatings on the stem containing mineral particles or antifeedant substances. One of these innovations (Conniflex) has been developed further and is now widely used in Swedish forestry.
