The Effect of UV Radiation on Myzus persicae and the Biological Control Agent Aphidius colemani
Gidske, Runa (Master thesis, 2020)Greenhouse light technologies are advancing, giving new opportunities in pest management such as UV treatments against pathogenic fungi. Little is known about how these methods affect other relevant organisms in protected ... -
Evaluation of the effects of Beauveria bassiana on the predatory mite Phytoseiulus persimilis
Dhami, Prasanna (Master thesis, 2022)The entomopathogenic fungus Beauveria bassiana (Balsamo) and the predatory mite Phytoseiulus persimilis are effective biological control agents of Tetranychus urticae (Acari: Tetranychidae), an economically important pest ... -
Potential of the green dock beetle (Gastrophysa viridula) as a biocontrol agent of northern dock (Rumex longifolius) in Norwegian grassland
Dybing, Ida (Master thesis, 2020)Docks (Rumex spp.) act as weeds in many parts of the world, and in Norwegian grasslands, the northern dock (Rumex longifolius) is the most widespread dock species. The ability of farmers to control docks without the use ... -
Tiltak for å hindre bladlusoverført virussmitte i norsk settepotetproduksjon
