2. 1. Studies in pest control for cultural property

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

   Abstract : 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. READ MORE

5. 3. 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

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

   Author : Biruk Ayalew Nurihun; Ayco J. M. Tack; Kristoffer Hylander; Ivette Perfecto; Stockholms universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Agroforestry; Arabica coffee; climate change; fungal disease; host-hyperparasite interaction; insect pest; minimum temperature and maximum temperature; shade cover; shade tree species; smallholder farmers; yield; Ecology and Evolution; ekologi och evolution;

   Abstract : Climate change and diseases are threatening global crop production. Agroforestry systems, which are characterized by complex multispecies interactions, are considered to provide nature-based solutions for climate change mitigation and pest and disease regulation. READ MORE

7. 5. Semiochemical-mediated attraction and oviposition in pyralid moths

   Author : Christian Olsson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ekologi; Lepidoptera; behaviour; pest control; Ecology; learning; olfaction;

   Abstract : Moths use chemical signals emanating from food to find sites for oviposition and subsequent larval feeding. By identifying these odours, novel approaches to pest management can be developed, such as monitoring of females in pest populations. READ MORE
