  1. 1. Can alteration in host odor blends change the olfactory preferences in Spodoptera littoralis?

    Master-uppsats, SLU/Department of Plant Breeding (from 130101)

    Författare :Hanna Olovsson; [2017]
    Nyckelord :host preference; Spodoptera littoralis; induction of feeding; cotton; olfactometer; y-tube;

    Sammanfattning : Gustatory and olfactory stimuli have been shown to induce feeding preferences in generalist phytophagous insect species. Generalists have to process a lot of information while performing host selection and it has been suggested that this may be a limitation, while it makes the host detection slower than for specialist species that process a lower amount of information.

  2. 2. Kilohertz electro-optics for remote sensing of insect dispersal

    Master-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Sandra Török; [2013]
    Nyckelord :LUMBO; remote sensing; dark-field spectroscopy; insect wingbeat modulation; Technology and Engineering;

    Sammanfattning : This thesis evaluates the possibilities of determining the flight direction of insects by analysing the wingbeat modulation pattern of the backscattered sunlight from insects. The Lund University Mobile Biosphere Observatory (LUMBO) was used during the summer of 2013 for a field campaign at two locations in Skåne, Sweden. LÄS MER

  3. 3. Codling moth, Cydia pomonella, antennal responses to Metschnikowia pulcherrima and Metschnikowia andauensis synthesised volatiles

    Master-uppsats, SLU/Plant Breeding and Biotechnology (until 121231)

    Författare :Tobias Lindblom; [2012]
    Nyckelord :Cydia pomonella; Codling moth ; Metschnikowia; yeast; volatiles ; GC EAD ; average; apple;

    Sammanfattning : Insect-yeast interactions have been known for decades but are poorly understood. To investigate the codling moth (Cydia pomonella ) olfactory connection to yeasts, volatiles from two ascomycete yeasts, Metschnikowia pulcherrima and Metschnikowia andauensis, were analysed using gas chromatography combined with electroantennographic detection (GC-EAD).

  4. 4. Olfactory detectability of amino acids in the European honeybee (Apis mellifera)

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Nellie Linander; [2011]
    Nyckelord :amino acids; olfaction; Apis melllifera; honeybee; proboscis extension reflex; olfactory detection threshold; classical conditioning;

    Sammanfattning : The honeybee is one of the model species in insect olfaction and its sense of smell is well studied. However, knowledge about the spectrum of odorants detectable to honeybees is limited. One class of odorants that has never been tested so far are the amino acids, which are important constituents of floral nectar. LÄS MER
