  1. 1. Chemical Communication and Mate Choice : Investigations into the Meaning of a Fruit Fly Pheromone

    Författare :Björn G. Johansson; Göran Arnqvist; Fredrik Widemo; Anders Berglund; Allen Moore; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Drosophila grimshawi; sexual selection; pheromone; mate choice; lekking; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : Chemical signals are the most widely used form of sexual communication throughout the living world. However, there is in general little knowledge about what these signals actually communicate. The role of chemical signals, i.e. LÄS MER

  3. 2. Chemical communication in mating shore crabs Carcinus maenas

    Författare :Mattias Ekerholm; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zoology; Urine communication; Behavior; Spatial scale; Male pheromone; Primer pheromone; Zoologi; Olfaction;

    Sammanfattning : Locating and evaluating a suitable partner for mating is one of the most important events in any sexually reproducing organism. To achieve this, an animal must be able to locate its partner over both long and short distances, and finally evoke the proper mating behaviour. LÄS MER

  4. 3. Circadian Rhythms in Moth Sex Pheromone Communication

    Författare :Germund von Wowern; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physiology of invertebrates; växtparasitologi; Entomologi; plant parasitology; Entomology; Ecology; Ekologi; locomotor activity; social synchronisation; PDH; corazonin; PBAN; pheromone response; sex phermone; Lepidoptera; Ryggradslösa djurs fysiologi; calling behaviour; circadian rhythm;

    Sammanfattning : Sex pheromone communication and related physiological processes are regulated by circadian clock mechanisms in many moth species. This thesis includes studies of circadian rhythms in sexually relevant behaviours and communication in the Egyptian cotton leafworm Spodoptera littoralis, the turnip moth Agrotis segetum, the Indian meal moth Plodia interpunctella and the Mediterranean flour moth Ephestia kuehniella.

  5. 4. Insights into the Evolution of Moth Pheromone Communication: Lessons from the European Corn Borer

    Författare :Jean-Marc Lassance; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biosynthetic enzymes; evolution; Ostrinia nubilalis; mate choice; mate finding; olfaction; biosynthesis; speciation; moth; pheromone; olfactory receptors.;

    Sammanfattning : Chemical communication by means of sex pheromones is central to the mating systems of a wide range of organisms. Because reproductive isolation is often based on pheromone differences, understanding how pheromones diverge is necessary for a complete comprehension of the speciation process. LÄS MER

  7. 5. Disruption of moth mating behaviour by olfactory and auditory cues

    Författare :Glenn Svensson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; ultrasound; predation risk; selection; heritability; flight tunnel; harmonic radar; pest control; mating disruption; pheromone communication; Pyralidae; Lepidoptera; Noctuidae; Animal ecology;

    Sammanfattning : The impact of olfactory and auditory cues on the mating behaviour in two species of moths, Agrotis segetum (Noctuidae) and Plodia interpunctella (Pyralidae), was investigated to evaluate their potential use in integrated pest management. The flight behaviour of male A. LÄS MER
