  1. 1. Ökad andel neonikotinoidbetad rapsareal visar ingen generell negativ effekt på förekomst av vildbin i Sverige

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Joakim Mathiasson; [2021]
    Nyckelord :Agriculture; Neonicotinoids; Pollination; Rapeseed; Seed treatment; Wild bees; Betningsmedel; Jordbruk; Neonikotinoider; Pollinering; Raps; Vildbin;

    Sammanfattning : Under 2013 förbjöds behandling av blommande grödor med de systematiska neonikotinoiderna imidakloprid, klotianidin och tiametoxam i EU. Ett flertal studier och rapporter hade visat att pollinerande biarter kan uppleva subletala effekter av att konsumera neonikotinoid. LÄS MER

  3. 2. Effects of low quality soil, drought and systemic pesticides on plant flowering traits in Brassica Napus L.

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Sofie Vessling; [2016]
    Nyckelord :Agriculture; Flower density; Pollen production; Insect pollination; Pollination; Drought; Low quality soil; Clothianidin; Climate change; Neonicotinoids; Brassica Napus; Plant resources; Rapeseed; Nectar production; Systemic pesticide; Flower traits; Agriculture and Food Sciences; Biology and Life Sciences; Earth and Environmental Sciences;

    Sammanfattning : One of the most important ecosystem services is animal pollination, which has been found to increase both crop quantity and quality and hence is important for sustainable food production. To provide food to an increasing population, farming systems are intensifying to maintain high crop yields. LÄS MER

  4. 3. An assessment of the risk of neonicotinoid pesticides to harm non-target insects - is current risk assessments sufficient?

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Elin Ingersdotter; [2016]
    Nyckelord :neonicotinoids; clothianidin; solitary bee; solitary wasp; risk assessment; pesticides; Earth and Environmental Sciences;

    Sammanfattning : Neonicotinoids, e.g. clothiandin, imidacloprid and thiamethoxam, is the most used class of insecticides worldwide. However, lately, this group of insecticides has been subject to controversy. LÄS MER

  7. 5. Neonicotinoids and honeybee health : the effect of the neonicotinoid clothianidin, applied as a seed dressing in Brassica napus, on pathogen and parasite prevalence and quantities in free-foraging adult honeybees (Apis mellifera)

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Julia Goss; [2014]
    Nyckelord :honeybees; pathogens; parasites; virus; Nosema; Varroa; neonicotinoids; clothianidin;

    Sammanfattning : Sub-lethal doses of neonicotinoids have been shown to negatively impact the health of honeybees. However, most studies to date have exposed bees only artificially to these pesticides under laboratory conditions. LÄS MER
