  1. 1. Effect of Touch on Cotton and Maize : influence on plant morphology and feeding preference in Spodoptera littoralis

    Kandidat-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Anna Magnusson; [2022]
    Nyckelord :Mechanical stimuli; cotton; maize; thigmomorphogenesis; Spodoptera littoralis; induced defence; plant-plant interaction;

    Sammanfattning : Plants are constantly exposed to touch and mechanical stimuli in natural environments, from rain, wind, animals and plant neighbours. However, current knowledge and understanding of how touch physiologically affects plants are limited. LÄS MER

  2. 2. 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

  3. 3. Friends with benefits? - Does gut microbiota of Spodoptera littoralis affect insecticide resistance and are there any costs of insecticide resistance development?

    Master-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Sarah Heithausen; [2021]
    Nyckelord :insecticide resistance development; gut microbiota; gut symbiont-mediated resistance; trade-off effects; fitness costs; symbiosis; survival; life-history traits; fecundity;

    Sammanfattning : The insect gut microbiota has many important functions for insects such as detoxification of host plant toxins. Recently there has been a growing interest on the effect of insect gut microbiota on insecticide resistance development. Insecticide resistance is a growing concern for food security and sustainable agriculture. LÄS MER

  4. 4. 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. 5. Transgenerational phenotypic plasticity: can parental host plant experience affect the phenotype of the offspring? : a study in behavior and physiology in Spodoptera littoralis

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

    Författare :Axel Rösvik; [2015]
    Nyckelord :transgenerational phenotypic plasticity; Spodoptera littoralis; performance; migration; preference;

    Sammanfattning : The Darwinian theory of natural selection first popularized by Charles Darwin in the mid-19th century has been widely accepted as one of the key mechanisms of evolution. However, before Darwin other scientists such as Jean-Baptiste de Lamarck had their theories about evolution. LÄS MER
