22. Gall midge olfaction and its role in speciation
Abstract : With the swede midge (Contarinia nasturtii) as our main model species, we study two types of olfactory cues that are of importance for gall midges: 1) the pheromones emitted by the female to attract the male; 2) and the host plant volatiles that the females use when finding a host for oviposition. We found that both the blend of compounds and the enantioisomeric form are important for male attraction in the wind tunnel and in the field. READ MORE

23. Social and environmental olfactory signals mediate insect behavioral ecology and evolution
Abstract : Odors are essential in mediating insect reproductive behavior. Environmental odors help insects locate suitable feeding or egg-laying sites and avoid suboptimal hosts or dangerous habitats. Sex pheromones, on the other hand, are responsible for mate finding and elicit courtship and mating. READ MORE

25. The biology and ecology of Phytophthora infestans: the role of cell wall proteins in development, pathogenicity and potato defence activation
Abstract : Phytophthora infestans was one of the first eukaryotic microbes to be implicated as the causal agent of a plant disease. Despite a relentless research effort over the last 150 years, it remains one of the most economically important phytopathogens today. READ MORE
