Incidence of aphid-transmitted viruses in raspberry and raspberry aphids in Norway and experiments on aphid transmission of black raspberry necrosis virus Open
Raspberry ( Rubus idaeus L.) is susceptible to aphid-borne viruses. We studied the incidence of four of them – black raspberry necrosis virus (BRNV), raspberry leaf mottle virus (RLMV), raspberry vein chlorosis virus (RVCV), and Rubus yell…

Pesticide use, arthropod fauna and fruit damage in apple orchards in a Nordic climate Open
BACKGROUND Integrated pest management (IPM) has a long history in fruit production and has become even more important with the implementation of the EU directive 2009/128/EC making IPM mandatory. In this study, we surveyed 30 apple orchard…

Distribution and Prolonged Diapause of the Rowan Seed Predators Argyresthia conjugella (Lepidoptera: Yponomeutidae) and Megastigmus brevicaudis (Hymenoptera: Torymidae) and their Parasitoids in Norway Open
The seed predator Argyresthia conjugella Zeller has rowan as its preferred host plant. In years of poor fruiting in rowan, it oviposits on apples. To improve the knowledge of this apple pest, rowanberries were collected from localities all…

Population density of eriophyid mites (Acari: Eriophyidae) on raspberry (Rubus idaeus) and their association with leaf blotch symptoms Open
Red raspberry, Rubus idaeus, is known to be infested by at least six species of eriophyid mites. Among them, the raspberry leaf and bud mite, Phyllocoptes gracilis, (Figure 1, A–B) is the only known vector of a raspberry virus, namely the …

Known and Potential Invertebrate Vectors of Raspberry Viruses Open
The estimated global production of raspberry from year 2016 to 2020 averaged 846,515 tons. The most common cultivated Rubus spp. is European red raspberry (Rubus idaeus L. subsp. idaeus). Often cultivated for its high nutritional value, th…

Predatory mites (Acari: Phytoseiidae) on wild blackberry in Norway - Results from a search for Amblyseius andersoni in August 2016 Open
Rovmidden Amblyseius andersoni er ønsket som ny nytteorganisme mot skadedyr i norske hagebruksvekster. Arten ble aldri funnet av Torgeir Edland, som undersøkte norsk rovmiddfauna på åtti- og nittitallet. Ettersom den er funnet på bjørnebær…

Cereal Straw Mulching in Strawberry—A Facilitator of Plant Visits by Edaphic Predatory Mites at Night? Open
In Norway, strawberry producers use cereal straw mulching to prevent berries from contacting the soil and to control weeds. We hypothesized that organic matter such as straw mulch also favors the maintenance of predatory mites which visit …

Prevalence and parasite load of nematodes and trematodes in an invasive slug and its susceptibility to a slug parasitic nematode compared to native gastropods Open
The invasive slug Arion vulgaris (Gastropoda: Arionidae) is an agricultural pest and serious nuisance in gardens of Central and Northern Europe. To investigate if the success of A.vulgaris in Norway can be attributed to a release from para…

The use of semiochemical mass traps to reduce mirid damage in strawberry crops. Open
Advances in the identification of attraction of mirids to semiochemicals has provided the opportunity to exploit synthetically produced sex pheromones and plant produced compounds for controlling pest species in crops. Sex pheromones of mi…

Management of insect pests using semiochemical traps Open
In the absence of effective control measures, the strawberry blossom weevil (Anthonomus rubi) (SBW) and the raspberry beetle (Byturus tomentosus) (RB) cause large (10 - >80%) losses in yield and quality in organically grown raspberry. Attr…
