1. Scent traps and trap crops for broad bean weevil (Bruchus rufimanus) control
Master-uppsats, SLU/Dept. of EcologySammanfattning : Bönsmyg (Bruchus rufimanus) är en skadeinsekt vars larv orsakar skada i åkerböna (Vicia faba minor L), vilket reducerar bönornas kvalitet och kommersiella värde. Detta projekts syfte var att testa och utvärdera doftfällor i kombination med fångstgrödor som en biologisk kontroll mot bönsmyg. LÄS MER
2. Bland granar och grannar : Ansvar och risk för granbarkborreangrepp i skog
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Juridiska institutionenSammanfattning : This thesis discusses the responsibility of and risk for infestations of spruce bark beetle. The spruce bark beetle, Ips typographus, is a natural part of the Swedish forest ecosystem but causes severe financial damage in forestry. Since 2018, the spruce bark beetle infestations have been substantial in Sweden. LÄS MER
3. Effects of plant-fungal interactions on volatile emission of Hordeum vulgare and aphid preference
Master-uppsats, SLU/Dept. of EcologySammanfattning : Barley is one of the most economically important cultivated crops in the world. However, barley is a host for many insect pests and plant pathogenic fungi which is a threat to the production. Rhopalosiphum padi is an economically important insect pest that leads to large economical losses in agricultural crops such as barley. LÄS MER
4. Implementation of Scheimpflug Lidar for Entomological Monitoring of Bark Beetles
Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/FörbränningsfysikSammanfattning : Bark beetles are responsible for great damages to Swedish forestry every year. This project focuses on a method of entomological lidar called Scheimpflug lidar to detect and monitor bark beetles. Scheimpflug lidar uses old techniques from photography to achieve a deep field of focus to resolve objects over long distances. LÄS MER
5. Planning for Viable Forests with High Biodiversity
Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildningSammanfattning : In recent decades, the rate of extinction of species is increasing due to human use and refinement of nature. This has resulted in a large amount of research throughout the world. Forestry today is mostly based on clear cuts, and many natural forests have been cut down and replaced with monocultured forests.
