    Abstract : Dogs, Canis familiaris, share the lives of humans all over the world. That dogs, and the behavior of dogs, are of interest to many is therefore no surprise. In this thesis, the main aim has been to identify factors that affect dogs’ behaviours.The dog, Canis familiaris, is our first domesticated animal. READ MORE

  5. 3. Male moth behaviour and perception in pheromone plumes

    Author : Peter Valeur; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; Grapholita molesta; Noctuidae; Lepidoptera; Tortricidae; behaviour; electrophysiology; single cell; flight tunnel; sex pheromone; wind tunnel; radar; flight; pre-exposure; mechanisms of mating disruption; Agrotis segetum; choice test;

    Abstract : Behaviour of male moths and electrophysiological responses of male pheromone-specific olfactory receptor neurones were studied in two model species, the oriental fruit moth Grapholita molesta and the turnip moth Agrotis segetum. The studies were aimed at elucidating the relative importance of different mating disruption mechanisms. READ MORE

  6. 4. Getting to know Trioza apicalis (Homoptera: Psylloidea) – a Specialist Host-Alternating Insect with a Tiny Olfactory System

    Author : Lina Kristoffersen; Biologiska institutionen; []

    Abstract : This thesis comprises ecological, morphological and physiological studies of the carrot psyllid Trioza apicalis (Homoptera: Psylloidea) with particular focus on olfaction. Data from inventories of winter habitats suggest that T. apicalis prefer Picea abies over Pinus sylvestris and Juniperus communis as winter hosts. READ MORE

  7. 5. Behaviour of Pine Sawflies in Relation to Pheromone-Based Pest Management
