From: Aphid populations and virus vector potential in potato fields across seasons and regions in Norway

Potential aphid virus vectors in potato fields in Norway at locations Grimstad, Grue, Stange, Stjørdal and Overhalla in the growing seasons 2016–2018, during the period from the emergence of the potato seedlings to the haulm destruction. A Proportion of vector and non-vector aphid species. B The most interesting group and species that are known to be virus vectors. Aphids collected in the period 11/8 to 8/9–2016 in Stange and 19/6 to 14/8–2017 in Stjørdal were not identified to species. NA undetermined.
