  2. 1. Insights into the Evolution of Moth Pheromone Communication: Lessons from the European Corn Borer

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

    Abstract : 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. READ MORE

  4. 2. Odour-mediated nectar foraging in the silver Y moth, Autographa gamma

    Author : Dainius Plepys; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; predation risk; Noctuidae; Lepidoptera; flight tunnel; GC-EAD; single sensillum; sprayer; ultrasound; floral volatiles; attraction; foraging; mate-finding; lilac aldehydes; olfactory receptor neurones; Ecology; Ekologi; Chemistry; Kemi;

    Abstract : It is well established that floral odours play a significant role in the nectar foraging behaviour in Lepidoptera and other insect orders. Floral odour may elicit searching, alighting and feeding behaviours alone or in concert with visual stimuli. READ MORE

  5. 3. Social and environmental olfactory signals mediate insect behavioral ecology and evolution

    Author : Felipe Borrero; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    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

  6. 4. Circadian Rhythms in Moth Sex Pheromone Communication

    Author : Germund von Wowern; Biologiska institutionen; []
    Keywords : 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;

    Abstract : 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.

  7. 5. Recognition and modulation of olfactory signals in the noctuid moth spodoptera littoralis

    Author : Ahmed Saveer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Food, mates and host plants are essential resources for plant-feeding insects. Optimal resource localization that fulfils the physiological need and reproductive goals of an insect is of utmost importance. READ MORE
