  1. 16. The importance of search behavior and movements for spatial distributions of herbivorous insects

    Författare :Petter Andersson; Peter Hambäck; Johan Ehrlén; Tomas Roslin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Olfactory search; Habitat heterogeneity; Species-traits; Immigration; Scaling relationships; Patch size; Plant-insect interactions; EAG; Odors; Pheromones; Plant Ecology; växtekologi;

    Sammanfattning : Insect populations commonly show large spatial variation in density, and much variation have been shown to be explained by the search behavior applied by the insect when locating habitat patches. This thesis explores the importance of odor-mediated attraction for immigration rates of herbivorous insects in relation to the size of the patches and the density of host plants within the patches.

  3. 17. Role of semiochemical in host finding, oviposition and sexual communication in Guatemalan potato moth Tecia solanivora

    Författare :Miriam Frida Karlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Semiochemicals are important cues in the interaction between plant and insects and between conspecific insects. Volatile compounds emitted by plants provide herbivorous insects with cues for host finding, selection and discrimination. In moths, female emitted sex pheromones enable conspecific males to find them for mating. LÄS MER

  4. 18. Structure and Function of Odorant Binding Proteins and Chemosensory Proteins in Moths

    Författare :Severine Jansen; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR structure; Ecology; Ekologi; Development; Lepidoptera; Odorant Binding Proteins; Chemosensory Proteins;

    Sammanfattning : Odorant Binding Proteins (OBPs) and Chemosensory Proteins (CSPs) are small soluble proteins found in the lymph of insect sensillae located on insect antennae. Odorant Binding proteins are implied in olfaction, by binding hydrophobic odorant molecules and transporting them to the olfactory receptor located on the dendrite of the olfactory neurons. LÄS MER

  5. 19. 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

  7. 20. Morphologican and functional studies on the Drosophila neuromuscular system during postembryonic stages

    Författare :Ana Beramendi; Rafael Cantera; Prof. Carlos Dotti; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drosophila; neuromuscular system; Rel-proteins; fly brain; rhythmic morphology; aging; ; Neurobiology; Neurobiologi;

    Sammanfattning : The nervous system of the fruit fly Drosophila melanogaster has emerged as an excellent model for fundamental neuroscience as well as for biomedical research of human neurological diseases. In this thesis, two aspects of the neuromuscular system have been investigated: the role of the IkB-protein Cactus in the larval neuromuscular junction and the morphology of motor terminals throughout adult life.
