1. Studies in pest control for cultural property
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
2. Structure elucidation of semiochemicals related to : Polygraphus poligraphus, Polygraphus punctifrons, Trioza apicalis, Whittleia retiella, Neodiprion edulicolus, Neodiprion scutellatus, Neodiprion knereri and Neodiprion virginianus
Sammanfattning : .... LÄS MER
3. Behaviour of Pine Sawflies in Relation to Pheromone-Based Pest Management
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. The relationship between climate, disease and coffee yield: optimizing management for smallholder farmers
Sammanfattning : 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. LÄS MER
5. Semiochemical-mediated attraction and oviposition in pyralid moths
Sammanfattning : 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. LÄS MER
