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

    Author : Fredrik Östrand; Biologiska institutionen; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Helena Hanson; Biodiversitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. The relationship between climate, disease and coffee yield: optimizing management for smallholder farmers
