Abstract

I 1998-2000 ble det biologiske mangfoldet av minerfluer undersøkt i konvensjonelt og økologisk dyrket korn og gras i Sørøst-Norge. Fluene ble fanget med håv i 1x10m store ruter i åkerkanten, 0,5, 5, 15 og 30 m ute i åkeren. Totalt 5822 individer av minst 66 arter ble fanget. Deler av biodiversiteten var høyere i de økologiske feltene. I både konvensjonelle og økologiske felt ble biodiversiteten redusert når en gikk fra åkerkanten og utover i åkeren. In 1998-2000 the species richness and species diversity of Agromyzidae were investigated in conventionally and biologically managed cereal and grass fields in Southeastern Norway.Flies were caught with sweep-net in 1x10 m plots in the boundary, 0.5, 5, 15 and 30 m into the fields. A total of 5822 specimens of at least 66 species were caught. Parts of the biodiversity was shown to be higher in biological fields. In bothconventional and biological fields the biodiversity was reduced when moving from the boundary and into the field.
