The basic story about neonicotinoids is that they are an insecticidal seed dressing applied to various agricultural crops such as oil seed rape to prevent either attack by insects themselves in the case of flea beetles with rape, or as with the current issue over sugar beet, aphids.

Let’s first take note of the current situation from which the discussion has stemmed: in December 2013 the European Commission issued a 2 year moratorium on the use of three specific neonicotinoids: imidacloprid, clothianidin and thiamethoxam. A large number of studies agree that neonicotinoids can lead to increased mortality, impaired feeding, foraging and locomotion behaviours, altered learning and memory, and reduced immunity. 3 Honey bees have also been shown to prefer sugar water solutions containing neonicotinoids.

The evidence from these is, to an extent, conflicting. Firstly, there’s no doubt that neonicotinoids can have detrimental effects on bees. Background There have been scientific studies published that suggest a link between the use of neonicotinoids and the declining health of honey bees in some regions. Unlike in other countries, and because of our unique ecosystem, the scientific information available indicates that managed and wild honey bee populations are not in decline in Australia. experiments to assess the effects of neonicotinoid-treated crops on three bee species across three countries (Hungary, Germany, and the United Kingdom).Winter-sown oilseed rape was grown commercially with either seed coatings containing neonicotinoids (clothianidin or thiamethoxam) or no seed treatment (control). For honey bees, we found 2017-11-09 Neonicotinoids have the potential to affect entire food chains. They are persistent in the environment, infiltrate groundwater, and have cumulative and largely irreversible effects on invertebrates.

16 Apr 2020 Indeed, acute exposure to neonicotinoids impairs navigation and homing in honey bees, as do chronic exposures, and quantitative models of

Three recent studies in which bees were dosed with neonicotinoids showed sub-lethal effects on bees [1-3]. The results from these studies contrast with a growing body of evidence from field studies that has failed to show an effect of neonicotinoids when bees are allowed to forage naturally in the presence of crops treated with neonicotinoids [4-8]. Neonicotinoid insecticides have been shown to have harmful effects on wildlife: from bumblebees and solitary bees, to aquatic invertebrates and even birds. With a partial ban in place in Europe, small steps have been taken to protect our wildlife, however there is still much more work to do.

In wild bees, the study found a link between higher levels of NNI residues and negative effects on reproduction: fewer queens in bumblebee hives and fewer egg cells in solitary bee nests. Neonicotinoid exposure led to fewer bumblebee queens and lower reproductive success in all three countries. Neonicotinoids also reduced the next year’s honey bee colonies in Hungary and the U.K., Neonicotinoids are a group of insecticides used widely on farms and in urban landscapes.
