  1. 1. Wireless Sensor Network for Controlling the Varroasis Spread within Bee colonies across a Geographical Region

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Venkat Sai Akhil Dasyam; Saketh Pokuri; [2024]
    Nyckelord :Wireless Sensor Networks; Monitoring and Control; Precision Beekeeping; Disease spread; Internet of Things.;

    Sammanfattning : Background: With the global decline of honey bee populations, safeguarding these vital pollinators has become crucial. Varroa destructor mites are a primary threat, weakening bees and facilitating the spread of diseases, which can decimate colonies and disrupt ecosystems. LÄS MER

  3. 2. Comparison of drone ecology and behavior between Apis mellifera mellifera and the hybrid Buckfast in southwestern Sweden

    Master-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Finja Schaumann; [2023]
    Nyckelord :;

    Sammanfattning : Most research on the biology of the western honey bee (Apis mellifera) focuses on the worker bees, but knowledge about drones is lacking despite their important role in mating with a virgin queen. Available information about their ecology and behavior are mainly based on direct observations in need of intensive experience and knowledge about honey bees. LÄS MER

  4. 3. 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.

  5. 4. A destructive host-shift : a comparative review of resistance mechanisms in the novel and original hosts of Varroa destructor

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Elin Sjögren Englund; [2022]
    Nyckelord :Varroa destructor; Apis cerana; Apis mellifera; host-shift;

    Sammanfattning : Apiculture has a major antagonist in Varroa destructor, the ectoparasitic mite that has become the most prominent driver of colony losses for the European honey bee, Apis mellifera. This was not always the case, as V. destructor is native to Asia and originally only infested the Asian honey bee, Apis cerana. As these two species have co-evolved, A. LÄS MER

  7. 5. Detecting Parasites on Bees with Mobile Object Detection

    Uppsats för yrkesexamina på avancerad nivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Karl Eriksson; [2021]
    Nyckelord :;

    Sammanfattning : Bee colonies are heavily threatened by a parasite. An anonymouscompany solves the problem by detecting the parasites with a mobile appusing Machine Learning (ML). It is based on cloud based computations andthey are currently exploring if it is possible to do the computations on thedevice instead. LÄS MER
