Members of 38 Degrees have asked us to look into whether restrictions on their use would be affected by leaving the European Union. 2017-06-29 2020-01-18 More recently, various laboratory-based studies (e.g., Gill et al., 2012; Henry et al., 2012; Whitehorn et al., 2012) have suggested that neonicotinoids have subtle, sublethal adverse effects on both bumble bees and honey bees, and these studies were influential in the imposition of a Europe-wide moratorium on their use of three neonicotinoid compounds on “bee friendly” crops in 2013 2017-09-19 2020-12-30 Neonicotinoids have a half-life (the time taken for half of the chemical to disappear) in soil of over three years, and will still be used on winter crops. The ban focuses on pollinating insects such as bees and has addressed those issues, but neonicotinoids have harmful effects on soil and aquatic invertebrates which haven’t been touched on. Bees and neonicotinoids - what's it all about?

The neonicotinoid family includes acetamiprid, clothianidin, imidacloprid, nitenpyram, nithiazine, thiacloprid and thiamethoxam. The second study, by Nadejda Tsvetkov and colleagues at York University in Toronto, Canada, investigated levels of neonicotinoids that bees encounter in corn-growing regions in Canada.

17 Mar 2015 The pesticides we're talking about here are neonicotinoids. These are insecticides and, since bees are insects, they can and will kill bees.

References 1. 2019-11-27 Most uses of neonicotinoid pesticides represent a risk to wild bees and honeybees, according to assessments published today by EFSA. The Authority has updated its risk assessments of three neonicotinoids – clothianidin, imidacloprid and thiamethoxam – that are currently subject to restrictions in the EU because of the threat they pose to bees. Neonicotinoids are active substances used in plant protection products to control harmful insects, which means they are insecticides The name literally means "new nicotine-like insecticides". They are chemically similar to nicotine The name neonicotinoids is sometimes shortened to "neonics" or "NNIs" 2021-01-09 Using lab-based colonies of buff-tailed bumblebees, the most common British bumblebee species, we showed that a neonicotinoid pesticide called imidacloprid turns night into day for bees.

In this article we are going to tackle a very sensitive topic, very relevant for today’s beekeeping: the effects of neonicotinoids on honey bees. 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. Neonicotinoids are a class of insecticides commonly used in agriculture and increasingly associated with declines in bee populations, and bee viability is an important concern given the utility 2017-06-30 Zayed and his team, in Canada, were interested in determining the levels of neonicotinoids that bees are exposed to in the field. They placed honey bee colonies either close to or far from neonicotinoid-treated corn and tested the bees, pollen, and nectar for more than … 2014-05-09 The weight of evidence indicated that exposure to neonicotinoids during the corn and soybean planting period contributed to bee mortalities in 2012 and 2013. Analytical results for bee samples collected in 2014, and evaluations of inspection results, are pending. There is clearly a pesticide problem with bees–even if we can't fully quantify it right now.The Xerces Society white paper, A Review of Research into the Effects of Neonicotinoid Insecticides on Bees, with Recommendations for Action, had this to say about CCD: "There is no direct link demonstrated between neonicotinoids and the honeybee bee syndrome known as Colony Collapse Disorder.
