  1. 21. Revisiting push-pull technology: Below and aboveground mechanisms for ecosystem services

    Författare :Aneth Bella David; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Push-pull technology is an effective and ecological solution to suppressing major Lepidopteran pests of cereals, in particular stem-borers (Busseola fusca, Chilo partellus), the fall armyworm (Spodoptera frugiperda) and the parasitic weed Striga. The technology exploits plant-insect interactions in intercropping practices to manage the pests, increasing productivity while maintaining ecosystem resilience. LÄS MER

  3. 22. Genetics and functions of innate-like lymphocyte subsets

    Författare :Julia Rolf; Göteborgs universitet; []
    Nyckelord :innate-like lymphocyte; CD1d; autoimmunity; genetic mapping; microarray; Salmonella infection;

    Sammanfattning : The immune system contains three different branches: innate immunity, adaptive immunity and innate-like lymphocytes that share properties both with the innate and adaptive immune cells. The innate-like lymphocytes have the capacity to rapidly become activated by invading pathogens and also to modulate immune responses and thereby inhibit or promote inflammation. LÄS MER

    Författare :Niklas Mattson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; zoologi; Zoology;

    Sammanfattning :  The thesis is a contribution to understanding the ecology of fish populations primarily in SubSaharan African small water bodies (SWBs). SWBs include ponds, small reservoirs, rivers and floodplains. LÄS MER

  5. 24. Regulation of B cell responses to modified self

    Författare :Emilie Grasset; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The immune system needs to be efficient to protect organisms from invading pathogens. Lymphoid organs such as the spleen and lymph nodes are needed to initiate the response. LÄS MER
