Mattias Larsson
My broad scientific interest is the evolution of olfactory and other sensory signals, the function of olfactory systems, and the application of olfactory attractants in conservation biology and pest management. In this context I study production and perception of olfactory signals, at different levels of evolution, genetics, sensory physiology and behaviour. I study these questions in a broad range of insect species and host systems, in order to understand how insects adapt to different olfactory environments.

Research

I study the olfactory system of the fruit fly, Drosophila melanogaster, and other drosophilid flies: the function of their olfactory systems and how this relates to their odour worlds. By performing targeted modifications in Drosophila, I study the function of specific components of the olfactory system.

Another main model system is the olfactory system and host selection mechanisms in the generalist noctuid moth Spodopteralittoralis: Variation in host preference hierarchies, including olfactory preferences and physiological adaptations to host plants, in relation to its polyphagous life style. Identification and characterization of its olfactory receptor genes, in collaboration with INRA Versaillses, France. Invasive potential and its impact on chemosensory information networks in novel environments within the ESF-funded INVAVOL project.

Among applied projects I have also initiated the PheroBio-project for monitoring of threatened insects with large-scale trapping based on pheromones and other semiochemicals in a landscape perspective. Our model systems include a broad range of saproxylic species, including the hermit beetle Osmoderma eremita, the click beetle Elaterferrugineus, several species of longhorn beetles and saproxylic moths. We also work with insects relevant to agricultural landscapes, such as burnet moths.
