(Journal article; Peer reviewed, 2017)The hepatitis C virus (HCV) is a major etiologic agent for severe liver diseases ( e.g . cirrhosis, fibrosis and hepatocellular carcinoma). Approximately 140 million people have chronic HCV infections and about 500 000 die ... -
Linking spatial distribution of Rhipicephalus appendiculatus to climatic variables important for the successful biocontrol by Metarhizium anisopliae in Eastern Africa
(Peer reviewed; Journal article, 2022-12-22)Cattle production is constantly threatened by diseases like East Coast fever, also known as theileriosis, caused by the protozoan parasite Theileria parva which is transmitted by ticks such as the brown ear tick, Rhipicephalus ... -
Linoleic Acid Promotes Emission of Bark Beetle Semiochemicals by Fungal Symbionts
(Peer reviewed; Journal article, 2022-12-30)Tree-killing bark beetles in conifer forests vector symbiotic fungi that are thought to help the beetles kill trees. Fungal symbionts emit diverse volatile blends that include bark beetle semiochemicals involved in mating ... -
Literature review for assessing whether os Mesophilic Processes on a Biogas Plant will reduce or eliminate Avena fatua (Floghavre), Echinochloa Crus-Galli (Hønsehirse), Synchytrium endobioticum (Potetkreft), Globodera rostochiensis and G. pallida (Potato Cyst Nematode).
(NIBIO RAPPORT;4(22) 2018, Research report, 2018-04-09)Bruk av husdyrgjødsel er stadig mer brukt til å produsere biogass. Rester (bio- avfall) etter biogass prosesser, kan bli bruk som gjødsel. Hvis ugressfrø, plante patogener og nematoder overlever anaerob prosessen, bruk av ... -
Long term effects of ionising radiation in the Chernobyl Exclusion zone on DNA integrity and chemical defence systems of Scots pine (Pinus sylvestris)
(Peer reviewed; Journal article, 2023-12-15)The Chernobyl Nuclear Power Plant (ChNPP) accident in 1986 resulted in extremely high levels of acute ionising radiation, that killed or damaged Scots pine (Pinus sylvestris) trees in the surrounding areas. Dead trees were ... -
Long-term preservation of potato leafroll virus, potato virus S, and potato spindle tuber viroid in cryopreserved shoot tips
(Journal article; Peer reviewed, 2018-10-06)Availability of and easy access to diverse plant viruses and viroids is a prerequisite in applied and basic studies related to viruses and viroids. Long-term preservation of viruses and viroids is difficult. A protocol was ... -
Longevity of plant pathogens in dry agricultural seeds during 30 years of storage
(Peer reviewed; Journal article, 2021-10-19)Plant diseases may survive and be spread by infected seeds. In this study we monitored the longevity of 14 seed-borne pathogens in 9 crop species commonly grown in the Nordic countries, in addition to a sample of sclerotia ... -
The lunar nodal phase cycle and winter atmospheric pressure as possible determinants of moth abundance: Analyses of a 30-year time series from South Norway
(Peer reviewed; Journal article, 2022-10-27)According to the plant stress hypothesis, population peaks of herbivores such as moths are caused by plant stress factors that force plants to reallocate stored defensive proteins to transportable and easily digestive ... -
