  1. 1. Studies in pest control for cultural property

    Författare :Thomas Strang; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; Pest control; cultural property collections; insect; mould; environment; integrated pest management; IPM; thermal control; pest risk to museum collections;

    Sammanfattning : This thesis considers discrete problems of protecting cultural property from pests and examines some of the solutions. Recent decades have seen a large change in how fumigants and pesticides are used in collections of cultural property. LÄS MER

  3. 2. Behaviour of Pine Sawflies in Relation to Pheromone-Based Pest Management

    Författare :Fredrik Östrand; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal ecology; effective sampling area; mark-release-recapture; climate; longevity; sampling range; Symphyta; Hymenoptera; monitoring; dispersal; polyandry; mating disruption; integrated pest management; behaviour; sex pheromone; Neodiprion sertifer; Diprionidae; Djurekologi; Zoology; Zoologi; Silviculture; forestry; forestry technology; Skogsvetenskap; skogsbruk; skogsteknik;

    Sammanfattning : Pine sawflies (Hymenoptera: Diprionidae) are severe pine defoliators. This thesis investigated sawfly behaviour related to the use of pheromones in integrated pest management, including monitoring with pheromone traps and mating disruption. LÄS MER

  4. 3. Natural enemies: Functional aspects of local management in agricultural landscapes

    Författare :Helena Hanson; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Agricultural intensification; sustainable agriculture; land use; management intensity; landscape scale; ecosystem services; biological control; species trait; pesticides; predatory arthropods; parasitoids; pollen beetles;

    Sammanfattning : Agricultural intensification has raised the global food production but also caused major concerns about environmental and health effects, including contamination by pesticides. Pesticide applications may induce toxicity not only on the target pest species but especially on non-target species. LÄS MER

  5. 4. Sex pheromone biosynthesis in moth pests : From gene discovery to biotechnological production

    Författare :Marie Dam; Feromongruppen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lepidoptera; Moths; Sex pheromones; Biosynthesis; Desaturases; Gene characterisation; Transcriptomics; Heterologous expression; Biotechnology; integrated pest management;

    Sammanfattning : Moths (Lepidoptera) are some of the most economically important pests in human agriculture. Conventional insecticides used for management promote insecticide resistance in addition to cause human- and environmental harm. This emphasises an inescapable need for sustainable alternatives and integrated practices. LÄS MER

  7. 5. Endophytic fungi in elms : implications for the integrated management of Dutch elm disease

    Författare :Kathrin Blumenstein; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Integrated pest management calls for new biocontrol solutions in management of forest diseases. Endophytic fungi that are commonly found in tree tissue may have potential in biocontrol. LÄS MER
