Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

The usage of plant protection products and biocontrol agents in soft fruit production has always been an important subject for the IOBC/WPRS Working Group "Integrated Protection of Fruit Crops" Study Group "Soft Fruits". The usage of pesticides and biological control methods varies considerably between countries and it is very difficult to get a good overview on the range of products that are applied or in development in soft fruits. In order to share and facilitate the flow of information, the Study Group "Soft Fruit" initiated a survey on the availability and usage of active ingredients and biocontrol agents in the different European countries in 2007. First, the most important pests and diseases in strawberry and raspberry production were identified. Then members of the different countries listed available products on the domestic market and indicated their usage in the field. So far 15 countries have contributed to the survey. The received data are accessible on the website http://www.any3.ch/IOBC/Softpest/index.html

Burot (Artemisia vulgaris) har de siste årene spredt seg raskt og er til stor sjenanse for mange. Ikke bare er den et plagsomt ugras, men den utgjør også et helsemessig problem. Norges Astma- og Allergiforbund (NAAF) regner med at 200.000 mennesker er allergiske mot burotpollen. Pollenet spres med vinden, men i et lavt luftsjikt og sjelden lengre enn 100-200 meter. Det vil derfor være effektivt å bekjempe burot lokalt, for å begrense allergiproblemer knyttet til burot nær barnehager, skoler, idrettsanlegg, boligområder og helseinstitusjoner.

Frøavl av stedegne planter til restaurering etter inngrep i fjellet kan bli en viktig nisjeproduksjon for norske frøavlere. Målet med prosjekt FJELLFRØ (2007-2010) er (1) å samle inn mormateriale, (2) å oppformere og utføre frøavlsforsøk, og (3) å anlegge demonstasjonsfelter med utprøving av stedegent plantemateriale i utvalgte anleggsområder i fjellet. Prosjektet eies av Telemark frøavlerlag (hovedeier), Norges Vassdrags- og Energidirektorat (NVE), Statkraft Energi AS, Forsvarsbygg og Felleskjøpet Agri. Til å utføre det faglige arbeidet i prosjektet har Styringsgruppa for FJELLFRØ engasjert Bioforsk og Norsk Landbruksrådgivning Østafjells. Foreliggende rapport gir en oversikt over oppformering og forsøk i 2009 og trekker opp videre planer for siste prosjektår 2010.

Insektene er blant de organismene som reagerer raskest på klimaendringer. De har kort generasjonstid, er svært mobile og utviklingshastigheten deres er direkte påvirket av temperaturen. Dette betyr at utviklingen fra egg til voksent insekt går raskere når temperaturen øker, noe som kan få store praktiske konsekvenser for skogbruket.

Today the spruce bark beetle Ips typographus is always univoltine in Northern Europe including Norway and completes development from egg to adult between May and August. Further south in Europe, development is bivoltine with the completion of two generations in most years. A temperature-driven developmental model suggests that by 2070-2100 the voltinism of I. typographus will change dramatically in Norway. If summers become only 2.5°C warmer than today bivoltinism can be expected every single year in the major spruce growing areas in S-Norway. This is likely to have dramatic effects on forestry since two generations per year will give two, instead of one, attack periods each summer. In addition to increasing the number of attacked trees the effect of the attacks may also be more severe, as Norway spruce is more susceptible to beetle attacks later in the summer. However, climate change will probably also change the phenology of Norway spruce and thus its susceptibility to attack by I. typographus and its phytopathogenic fungal associates. We are currently modelling how tree resistance varies with temperature and tree phenology in order to provide more well-founded advice to forest managers on the interaction between bark beetles and tree in a future climate.

VKM"s Panel 9 gives the following main conclusions of part 2 of the risk assessment: 1) Under the present climatic conditions, and if no control measures are taken, an introduction of PWN to the PRA area will not cause increased pine tree mortality. The level of uncertainty of this assessment is low. 2) Assuming the IS92a climate change scenario for the period 2000-2049 (RegClim), which involves a ~2 ºC temperature increase by the end of the period, an introduction of PWN to the PRA area will, if no control measures are taken, cause a minor increase in pine tree mortality (300 trees per year on average). The mortality can become larger if the temperature increases more than 2 ºC, and will gradually increase with time after 2049 due to spread of PWN. The level of uncertainty of these assessments is medium to high. 3) Any effects of PWN presence in the PRA area on export of wood and wood products will be of little importance. The level uncertainty of this assessment is low. 4) It will be almost impossible to eradicate PWN once it has been introduced to the PRA area. The level of uncertainty of this assessment is low. 5) The cost of a single eradication event as described in the preliminary contingency plan for the PRA area is approximately 700 mill. NOK. Due to expected spread, the total cost of eradication attempts following one introduction event will be approximately 2000 mill. NOK for the first 50 years. The level of uncertainty of these assessments is medium. 6) The negative effects of the control measures on the environment will be major. The level of uncertainty of this assessment is low.
