    Sammanfattning : Antennal detection and central nervous integration of behaviourally relevant odours in scarab beetles (Coleoptera: Scarabaeidae) was investigated, using the two Japanese scarabs Anomala cuprea and Phyllopertha diversa (Rutelinae), and the Central African fruit chafer Pachnoda marginata (Cetoniinae) as model species.

  2. 2. Evolution of mate signalling in moths: Biosynthetic gene families and diversification of female sex pheromones

    Detta är en avhandling från Chemical Ecology and Ecotoxicology, Department of Biology, Lund University

    Författare :Marjorie Liénard; Lund University.; Lunds universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; duplication; transcriptome; fatty-acyl-CoA reductase; fatty-acyl-CoA desaturase; fatty-acid biosynthesis; odour; insect; Lepidoptera; phylogeny; qPCR; heterologous expression; mutagenesis;

    Sammanfattning : Pheromones are intraspecific chemical signals serving as a ubiquitous form of communication, particularly among insects. Female sex-pheromone signals act as the core constituent in the specialized odour-mediated moth mate-recognition system. Female moths typically release multicomponent mixtures of alcohols, aldehydes or acetates. LÄS MER

  4. 4. Flower Cues for Hawkmoths: Colour, Place and Odour

    Detta är en avhandling från Department of Cell and Organism Biology, Lund University

    Författare :Anna Balkenius; Lund University.; Lunds universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zoologi; Zoology; olfaction; vision; learning; multimodal; Macroglossum stellatarum; Hawkmoth; Deilephila elpenor;

    Sammanfattning : Flowers use different cues to attract pollinators including colour and odour. How do hawkmoths use these cues to find the flowers? This question was investigated in two species of hawkmoth, the diurnal species, Macroglossum stellatarum, and the nocturnal species, Deilephila elpenor. Both species have colour vision and D.

  5. 5. Airway sensory hyperreactivity linked to capsaicin sensitivity. Definitions and epidemiology

    Detta är en avhandling från Department of Cell and Organism Biology, Lund University

    Författare :Åke Johansson; Göteborgs universitet.; Gothenburg University.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Capsaicin; Chemical sensitivity; Epidemiology; Odour intolerance; Sensory hyperreactivity;

    Sammanfattning : Aims: ? To study the relationship between odour intolerance and capsaicin sensitivity and to develop a definition of airway sensory hyperreactivity (SHR). ? To study epidemiology of odour intolerance; particularly regarding airway symptoms, and to relate odour intolerance to possible risk factors. LÄS MER
