Biography
My main research topic is plant pathology related to fruit growing. My researcher carrier started with a PhD about fungal fruit decay in sweet cherries. Later on it has been a wider focus with fruit rot on apple, plum and sweet cherry fruits in addition to important diseases on the trees such as European canker and bacterial canker. The research is done in cooperation with the fruit industry and related industries such as packinghouses and nurseries.

It is highly unlikely that Anagyrus vladimiri will be able to establish or spread in Norway. There are no native host organisms, and winter temperatures are too low. Therefore, it is likely that the parasitic wasp will not affect local biodiversity. Thus concludes the Norwegian Scientific Committee for Food and Environment (VKM). Background VKM has assessed the environmental risk of using the product Citripar in Norway. The risk assessment was carried out at the request of the Norwegian Food Safety Authority. Citripar, a product for biological control, is being sought for approval for use in Norway. The product contains the parasitic wasp Anagyrus vladimiri and is intended to be used against mealybugs, especially the species Planococcus citri and P. ficus, on fruits, berries, vegetables, and herbs in greenhouses and plastic tunnels, as well as on indoor plants. Conclusions There have been no reported observations of Anagyrus vladimiri in Norway. VKM assesses that Anagyrus vladimiri will not be able to establish and spread in Norway under current conditions. Anagyrus vladimiri will have no effect on biological diversity in Norway, as there are no known native host organisms that the wasp can parasitize. Individuals of what is now known as Anagyrus vladimiri were for many years identified as belonging to the species Anagyrus pseudococci. Anagyrus pseudococci and A. vladimiri belong to a complex of species that are almost impossible to distinguish from each other and are informally referred to as the Anagyrus pseudococci complex. The risk assessment is approved by VKM's Panel on Plant Health.
