The ... -
Begrenset kartlegging av virusoverførende bladlus i potet i Norge i 2011
Klingen, Ingeborg; Eklo, Toril; Spetz, Carl (Bioforsk rapport;7(105) 2012, Research report, 2012-02-02)Bladlusoverført virus er et problem i potet i Norge. Hvert år er det settepotetpartier i den sertifiserte avlen som ikke kan godkjennes fordi innholdet av PVY/PVA er for høye. For høyt virusinnhold i potetprodusentenes ... -
Cereal straw mulching in strawberry—A facilitator of plant visits by edaphic predatory mites at night?
Esteca, Fernanda de Cássia Neves; Trandem, Nina; Klingen, Ingeborg; Santos, Jandir Cruz; Delalibera Júnior, Italo; de Moraes, Gilberto José (Peer reviewed; Journal article, 2020-06-13)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 ... -
Computer-assisted image processing to detect spores from the fungus Pandora neoaphidis
Korsnes, Reinert; Westrum, Karin; Fløistad, Erling; Klingen, Ingeborg (Journal article; Peer reviewed, 2016)This contribution demonstrates an example of experimental automatic image analysis to detect spores prepared on microscope slides derived from trapping. The application is to monitor aerial spore counts of the entomopathogenic ... -
Effect of three isolates of Pandora neoaphidis from a single population of Sitobion avenae on mortality, speed of kill and fecundity of S. avenae and Rhopalosiphum padi at different temperatures
Saussure, Stephanie; Westrum, Karin; Hjelkrem, Anne-Grete Roer; Klingen, Ingeborg (Journal article; Peer reviewed, 2019)We studied the effect of three Pandora neoaphidis isolates from one Sitobion avenae population, three temperatures, and two aphid species namely S. avenae and Rhopalosiphum padi on (i) aphid mortality, (ii) time needed to ... -
Entomopathogenic fungal conidia marginally affect the behavior of the predators Orius majusculus (Hemiptera: Anthocoridae) and Phytoseiulus persimilis (Acari: Phytoseiidae) foraging for healthy Tetranychus urticae (Acari: Tetranychidae)
Jacobsen, Stine K.; Klingen, Ingeborg; Eilenberg, Jørgen; Markussen, Bo; Sigsgaard, Lene (Journal article; Peer reviewed, 2019-11-20)We determined how conidia of arthropod-pathogenic fungi on leaves affected the behavior of two predators—Orius majusculus (Hemiptera: Anthocoridae) and Phytoseiulus persimilis (Acari: Phytoseiidae)—when offered a choice ... -
Fungal isolate and crop cultivar influence the beneficial effects of root inoculation with entomopathogenic fungi in strawberry
Canassa, Fernanda; D'Alessandro, Celeste P.; Sousa, Sidcleide B.; Demétrio, Clarice G. B.; Meyling, Nicolai Vitt; Klingen, Ingeborg; Delalibera Jr., Italo (Peer reviewed; Journal article, 2019-10-28)BACKGROUND Root inoculations of crop plants with beneficial fungi constitute a promising strategy for growth promotion and control of above‐ground pests and diseases. Here, strawberry roots (cultivar ‘Albion’ and ‘Pircinque’) ... -
