  1. 11. Analysis of organic compounds in the rhizosphere soil of Cyperus rotundus using LC-MS

    Master-uppsats, KTH/Kemi

    Författare :Daniel Ruotsalainen; [2018]
    Nyckelord :LC-MS; Method development; Rhizosphere soil; Cyperus rotundus; SPE; LC-MS; Methodutveckling; Rhizosphere jord; Cyperus rotundus; SPE;

    Sammanfattning : Den presenterade studien hade som syfte att utveckla en extraktions-, provpreparerings- och analysmetod för jorden, i vilken gräset Cyperus rotundus växer, i ett försök att identifiera möjliga äggläggningsattraherande ämnen för myggan Anopheles gambiae. Högupplösande vätskekromatografi med hydrofob stationär fas (RP-HPLC, en. LÄS MER

  3. 12. The role of odor receptor protein Or22a in Drosophila melanogaster oviposition and the response spectra of chimeric receptor protein Or22a-b

    Kandidat-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

    Författare :Lovisa Pettersson; [2018]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : The fruit fly Drosophila melanogaster has a well-studied olfactory system. A crucial part of the olfactory system is the olfactory sensory neurons (OSNs). One type of these OSNs, Ab3a, expresses the Odor receptors (ORs) Or22a and Or22b. LÄS MER

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

    Master-uppsats, SLU/Dept. 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.

  5. 14. Nutrient driven oviposition and food preference in terrestrial herbivorous insects - a choice experiment

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Linnéa Waara; [2016]
    Nyckelord :Herbivore-plant interactions; offspring survival; Salix viminalis; Phratora vitellinae; Lochmaea caprea; C:N ratio; CO2 emissions;

    Sammanfattning : The presence of competitors and predators as well as plant quality affect which plants an insect feed from. These factors affect food choice through the entire insect life cycle, and is especially important when it comes to nurturing larvae. LÄS MER

  7. 15. Äggläggningspreferenser för honor av väddnätfjäril, Euphydryas aurinia, på området Bälsalvret, Gotland

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Lina Fransson; [2015]
    Nyckelord :Euphydryas aurinia; Oviposition preferences; Succisa pratensis; Euphydryas aurinia; äggläggningspreferens; Bälsalvret; Succisa pratensis;

    Sammanfattning : This study aims to get a better understanding of the oviposition-behaviour of the butterflyMarsh Fritillary (Euphydryas aurinia), in the area Bälsalvret on the Island of Gotland. Thestudy may provide helpful information to aid the conservation of the species in the area andalso provide overall knowledge about the female’s preferences when it comes to choosingmicrohabitat and host plant for their eggs.
