1. Impact of benthic macrofauna on sediment biogeochemistry - the importance of bottom water oxygen concentrations
Sammanfattning : .... LÄS MER
2. Chemical signals in interactions between Hylobius abietis and associated bacteria
Sammanfattning : The pine weevil (Hylobius abietis L.) is one of the two topmost economically important insect pests in Swedish conifer forests. The damage increase in areas were the silvicultural practice is to use clear cuttings were the insects gather and breed. LÄS MER
3. Microbes Associated with Hylobius abietis : A Chemical and Behavioral Study
Sammanfattning : This thesis is based on three inter-related studies: the first part deals with the microbial consortium, the identification of microbes and their volatiles, the second part deals with the study of bio-chemical control methods of two conifer pests; the pine weevil Hylobius abietis (L.) and the root rot fungi Heterobasidion spp. LÄS MER
4. Chemical defence in Norway spruce
Sammanfattning : Norway spruce (Picea abies) responds to stress by biosynthesis of chemical substances, which can deter invading insects or pathogens. Some of these substances are volatile and can be emitted to the surroundings while others are accumulated within the tree. LÄS MER
5. Oviposition cues as a tool for developing a new malaria control strategy
Sammanfattning : Anopheles gambiae sensu lato mosquitoes are among the dominant malaria vectors in sub-Saharan Africa. However, not much is known about the oviposition behaviour of these species necessary for the development of malaria vector control strategies. LÄS MER
