  1. 1. Födovalspreferenser hos en arktisk specialist : vad föredrar Gynaephora groenlandica (Lepidoptera:Erebidae) att äta på Wrangelön?

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Beatrice Elfvenfjärd; Erika Åmansson; [2022]
    Nyckelord :Gynaephora groenlandica; arktisk ullbjörnslarv; födopreferenser; arktisk tundra; arktisk specialist; växtegenskaper;

    Sammanfattning : The Arctic tundra has many unexplored areas. Due to the harsh climate and the difficult accessibility, there is a lack of knowledge about the different species that live under these circumstances. Herbivores in this environment have a large effect on the plant community, one of these is the moth butterfly larva Gynaephora groenlandica. LÄS MER

    Sammanfattning : Flounder, Platichthys flesus, is considered to be an important predator on blue mussels, Mytilus edulis, in the Baltic Sea. The purpose of this study was to investigate if flounder diet, i.e. blue mussels, could have an impact on the relationship between weight and length of flounders, i. LÄS MER

  5. 4. Feeding preferences and foraging in Larvae of Manduca sexta and Spodoptera littoralis : a laboratory study based on olfaction

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Elin Nyström; [2013]
    Nyckelord :Manduca sexta; Spodoptera littoralis; larvae; foraging; olfaction; larval dual choice test; induced feeding preference;

    Sammanfattning : Larvae of Lepidopteran Manduca sexta and Spodoptera littoralis are pests of economical importance in several horticultural and agricultural crops. Knowledge of insect feeding preferences and behavior is crucial in order to find economically and ecologically sustainable solutions to the problems caused by these herbivores. LÄS MER
