Several aphid species pose serious treats to potato crops by causing direct damage to the plants and/or indirectly by transmitting viruses. Different morphological forms and phenotypic plasticity among aphids complicates taxonomy and identification and thus makes targeted pest management in potatoes challenging. To obtain an overview of aphids frequenting potato fields in Norway, we investigated seasonal and annual changes in aphid populations in five potato fields (58–64 °N) over a three-year period (2016–2018), using yellow pan traps. In total 2218 of the 6136 collected aphids were identified by traditional barcoding, meaning sequencing a ~ 650 fragment of the mitochondrial COI gene. This revealed 137 different species, of which 111 were identified at the species level. The remaining were identified only to the genus level, indicating potential novel species. The southernmost sampling location yielded the highest number of species and individual counts, although no clear correlations to climate factors (temperature/precipitation) was observed. Of the 111 species identified, at least 39 are potential vectors of potato virus Y (PVY) and nine species may also transmit potato virus A (PVA). Knowledge on virus vector and non-vector aphid abundance and phenology have the potential to improve pest management of potato cultivation.

REKORN: Can regenerative cultivation methods contribute to reduce the risk of fungal diseases in cereals?
Regenerative agriculture is referred to as a bridge between organic and conventional agriculture and has received increased attention in recent years. Regenerative agriculture focuses on soil health and cultivation measures that can stimulate soil life and plant growth. An improvement in soil health is visualized, among other things, in increased carbon storage in the soil, limited soil compaction and increased microbiological diversity. The methods used to improve soil health within cereal cultivation may include crop rotation, reduced tillage, intercropping, use of catch crops and surface composting where plant residues are mixed into the top-soil layer.

REKORN: Kan regenerative dyrkingsmetoder bidra til å redusere risiko for soppsjukdommer i korn?
I prosjektet «REKORN» ønsker vi å sammenlikne plantehelsa i korn fra skifter dyrket med ulike dyrkingsmetoder som benyttes innen regenerativt landbruk. Gjennom REKORN ønsker vi å utvikle kunnskap om sammenhengen mellom jordhelse og plantehelse.
