    Sammanfattning : Att stoppa utarmning av biologisk mångfald och livsmiljöer är en stor utmaning och en ödesfråga för mänskligheten. Klimatförändringar, exploatering, kalhyggesskogsbruk, intensivt brukad jordbruksmark, invasiva arter och miljögifter medför att jorden är inne i sitt sjätte utdöende. LÄS MER

  3. 2. Effects of plant-fungal interactions on volatile emission of Hordeum vulgare and aphid preference

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Bina Johansson; [2022]
    Nyckelord :volatile organic compounds; chemical communication; Trichoderma atroviride; Fusarium graminearum; Rhopalosiphum padi; biological control;

    Sammanfattning : Barley is one of the most economically important cultivated crops in the world. However, barley is a host for many insect pests and plant pathogenic fungi which is a threat to the production. Rhopalosiphum padi is an economically important insect pest that leads to large economical losses in agricultural crops such as barley. LÄS MER

  4. 3. The effect of gut microbiota and insecticide resistance on host plant preferences and voracity of the cotton fly, Spodoptera littoralis

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

    Författare :Vaida Dzemedzionaite; [2021]
    Nyckelord :Insecticide resistance; gut microbiota; insect pest; host plant preference; sustainable agriculture;

    Sammanfattning : To counteract pesticide resistance development, it is crucial to understand why and when it evolves. Additionally, to inform the farmers about this term and provide advices on efficient pest management strategies to prevent pesticide resistance. LÄS MER

  5. 4. Construction of Gene Libraries from Environmental Isolates for expression in Pseudomonas putida

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Helga Helgadóttir; [2018]
    Nyckelord :applied microbiology; teknisk mikrobiologi; Biology and Life Sciences; Technology and Engineering;

    Sammanfattning : Currently most aromatic compounds used in industry are derived from unsustainable petro-chemical feedstock. However the depolymerization of lignocellulosic biomass generates a wide range of aromatic compounds that could be further valued through microbial conversion with microorgansims such as the bacterium Pseudomonas putida.

  7. 5. The Basis of Reproductive Isolation Between Ecologically Divergent Host Plant Races

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Emma Kärrnäs; [2018]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Insects and their host plants constitute a considerable proportion of the diversity on earth, and host shifts hence provide excellent study systems to study the process that drive diversification. In this study, I address what the mechanism to achieve assortative mating is in two host races using different host plants to increase our understanding of how reproductive isolation can arise in the face of ecological specialization.
