  1. 6. Evaluation of volatile organic compounds related to board based packaging by use of instrumental and sensory analysis

    Författare :Gunnar Forsgren; Fredrik Winquist; Ola Karlsson; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The main topic of the thesis is characterisation and evaluation of volatile organic compounds emitted by packaging materials based on paperboard products. The properties and concentration of these compounds are critical to how well these materials perform when applied as a main component of food packaging. LÄS MER

  3. 7. Odor perception in three Coleoptera: molecule, receptor & neuron

    Författare :Jonas Bengtsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis, the sense of olfaction and its links to behavior was studied in the cetoniid chafers Pachnoda interrupta and P. marginata, and the bark beetle Ips typographus. P. interrupta is a pest on sorghum in Ethiopia, and I. LÄS MER

  4. 8. Recognition and modulation of olfactory signals in the noctuid moth spodoptera littoralis

    Författare :Ahmed Saveer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : 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. LÄS MER

  5. 9. Olfactory mechanisms of host selection in phytophagous insects : behavior, neuron, and receptor

    Författare :Muhammad Binyameen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The most challenging tasks for phytophagous insects are the location and selection of mates, food sources, and oviposition sites, all crucial for survival and reproduction. To perform these tasks insects rely largely on their sense of smell (olfaction). LÄS MER

  7. 10. Examining neurobehavioral effects of chemosensory exposure to local irritants using event related potentials

    Författare :Stephanie Anja Juran; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The aim of this thesis was to examine whether unpleasant odors disturb cognitive task performance. At first glance, it seems intuitive that for example the smell of fire smoke would immediately interrupt my current writing at the computer. LÄS MER
