  1. 1. Jämförelse av patogenprevalens hos vilda humlor på olika avstånd från honungsbisamhällen : och skillnader i patogenförekomst mellan olika arter av kommersiella pollinerare

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Julia Carlsson; [2023]
    Nyckelord :Apis mellifera; Bombus terrestris; vilda pollinerare; patogenprevalens;

    Sammanfattning : Idag minskar den inhemska populationen av pollinerare till följd av klimatförändringar och urbanisering. För att bibehålla den livsviktiga pollineringen används bland annat samhällen av honungsbin (Apis mellifera), vilket antas kunna påverka de vilda humlorna negativt genom exempelvis konkurrens om resurser och patogenspridning.

  3. 2. The relationship between the prevalence of ten known pathogens in wild swedish bees and the presence of a nearby apiary.

    Kandidat-uppsats, Uppsala universitet/Institutionen för medicinsk cellbiologi

    Författare :Frida Sundblad; [2021]
    Nyckelord :Bombus terrestris; Apis mellifera; Deformed wing virus; pathogen spillover; commercial bumblebee production;

    Sammanfattning : Pollination by insects is of great importance for the global food production. There is a specific need for pollination by bees in greenhouses and tunnel cultivations to increase the quantity, quality and market value of the crops. LÄS MER

  4. 3. The impact of managed honeybees and commercial reared bumblebees on pathogens in wild bees

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Sofie Tinggren; [2020]
    Nyckelord :honey bee; bumblebee; diseases; commercial bees; bee intensity;

    Sammanfattning : Bees are important beneficial insects due to their ability to pollinate our crops and vegetables, as well as being critically important for maintaining wild floral biodiversity. Bees are important from both an economic perspective and an environmental perspective, which highlights the importance of having healthy and sustainable bee populations. LÄS MER

  5. 4. Bumblebee learning flights at a flower : viewing direction on departure is influenced by landmark position on approach

    Master-uppsats, Linköpings universitet/Biologi

    Författare :Michael Plante-Ajah; [2019]
    Nyckelord :bumblebee; bee; learning flight; insect navigation;

    Sammanfattning : Bumblebees, like other Hymenopterans, perform learning flights when departing their nest for the first few times or when departing from a newly discovered food source. As bees can learn about the landmarks around a flower both on approach and on departure, it is possible that what they see and learn on approach affects what they focus on during their learning flight on departure.

  7. 5. Beekeepers usage of IoT : Data collection, sharing and visualization in the domain of beekeeping.

    Master-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :Björn-Erik Adrian Zetterman; [2018]
    Nyckelord :Beekeeping; IoT; Wireless Sensor Networks; sensors; scales; electronics in agriculture; internet of bees; information and user’s needs; bee colony monitoring; precision beekeeping; sharing; usability;

    Sammanfattning : This master thesis is exploring Beekeepers usage of Internet of Things, or “Internet of Bees”. Since most of the prior contributions are focusing on data gathering, the approach to focus on the users needs is central to take next steps in the field of using IoT for Beekeeping. LÄS MER
