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.

I 2002 ble det beskrevet en ny orden av insekter som ble gitt navnet Mantophasmatodea. Utbredelsen av de 16 nålevende insektene som hittil er funnet, er begrenset til de sørlige deler av det afrikanske kontinent. Disse vingeløse insektene er små rovdyr med mange bygningstrekk som skiller dem fra andre insekter.

Sammendrag
Fusarium head blight (FHB) is a widespread and destructive disease of cereals caused by a number of Fusarium species. Under field conditions a mixture of Fusarium species exists. While FHB in wheat has been well studied, Fusarium infection of oats has not yet been characterized. Little is known about how the presence of a mixture of different Fusarium species in the same sample affects the mycotoxin production. During flowering plants of wheat and oats grown under greenhouse conditions were spray inoculated with single and multiple Fusarium species (F. graminearum, F. culmorum, F. avenaceum, F. poae and F. langsethiae). Chemical toxin analysis of harvested grain showed that the content of mycotoxins in oat were generally lower than in corresponding wheat samples. Neither T-2 nor HT-2 was detected in wheat or oat. Neither was it possible to detect F. langsethiae in the kernels when analysed by real-time TaqMan PCR. All wheat samples inoculated with F. graminearum contained relative high levels of deoxynivalenol. Samples infected with F. culmorum contained nivalenol in addition to deoxynivalenol. Moniliformin was detected at levels below the quantification limit in one third of the samples. The inoculation experiment was repeated with an adjusted inoculation procedure for F. langsethiae and F. poae, resulting in good establishment of all Fusarium species. The amounts of the different Fusarium species and the level of the corresponding mycotoxins were determined. The interactions between the Fusarium species regarding establishment on the fungus on the developing kernels and the production of the mycotoxins, will be discussed.
