Sulfoxaflor and flupyradifurone: Neonicotinoids or not ?

see also   Bee Die-offflupyradifurone

New Insecticides Escalate Indiscriminate Harm to All Organisms  (Beyond Pesticides, October 9, 2020) A new study demonstrates that emerging “novel” insecticides can cause significant, sublethal harm to beneficial organisms at typical “real life” exposure levels.sources. As the study paper notes, “Field-realistic applications of neonicotinoids can have significant sub-lethal impacts on beneficial insects, with knock-on effects on ecosystem services. This has resulted in bans and restriction on neonicotinoid use globally, most notably in the European Union.”      Sulfoxaflor and flupyradifurone, like neonics, are systemic insecticides. Flupyradifurone can persist in soils for months or years, whereas sulfoxaflor’s half-life in soil is two or three days. Research data reviewed by the subject study suggest that beneficial insects will be exposed to these compounds at relatively high concentrations in agricultural environments.      The researchers learned that flupyradifurone can have lethal impacts at field-realistic levels, with some kinds of bees being more vulnerable than others; further, and unsurprisingly, exposures to the compound were more likely to be harmful in combination with other environmental stressors, such as poor nutrition, pathogens, or other agricultural chemicals. .   The study also shows that sulfoxaflor has negative impacts on bee reproduction similar to those of neonics, particularly reduced reproduction (egg laying) and poor larval development, and that flupyradifurone exposures impair bees’ flight behavior, foraging success, and bodily temperature regulation

Insecticides the Pesticide Industry Said Were “Safer for Bees” Found to Stress and Kill Honey Bees    (Beyond Pesticides, June 23, 2020)  'As reported, a study by researchers at Oregon State University in the journal PLOS Onesulfoxaflor and flupyradifurone (in the products Transform and Sivanto, respectively) were found to increase apoptosis (cell death) and increase oxidative stress in exposed honey bees. The study indicates that, “With the recent Environmental Protection Agency (EPA) approval for use of both flupyradifurone and sulfoxaflor, and with the growing concern regarding pollinator health, it is important to better understand any potential negative impacts (especially sub-lethal) of these pesticides on bees.” However, this statement begs the question ‘why these two new bee-toxic pesticide were approved by EPA in the first place.’.    Independent scientific data has already been established on the harm these pesticides pose to pollinators. Last year, EPA registered new uses of sulfoxaflor, despite these warning signs. “Proposing to register sulfoxaflor for use on bee-attractive crops, in the midst of an ongoing pollinator crisis, is the height of irresponsibility,” said Drew Toher, community resource and policy director for Beyond Pesticides in an interview for Bloomberg Environment. “When all of the available data points to significant risks to pollinators from use of this chemical, we must face the facts: EPA is working towards the protection of pesticide industry, not the environment,” he said. EPA is in the midst of a lawsuit challenging its approval of sulfoxaflor.  The Saving America’s Pollinators Act (SAPA) was amended last year by Representative Blumenhauer to include immediate restrictions in the use of flypyradifurone and sulfoxaflor, in addition to the neonicotinoid insecticides that continue to poison pollinator populations. (US readers: go to the original article for action on this issue)    SNAP Comment: Well, the insecticides are also approved in Canada. As of 10 July 2020, 5 labels (including Transform) are listed for sulfoxaflor and 6 labels for flupyradifurone including Sivanto. As the question of why these products were approved, I suspect it is as replacement for neonicotinoids banned or about to be banned. Another indication that banning one produt at a time after a replacement is found is ridiculous to ensure safety. 

Sulfoxaflor and flupyradifurone:  Neonicotinoids or not ? (PAN Europe, Sept 2016)   The pesticide industry is trying to hide the reality behind two new chemicals that are similar to the notorious group of neonicotinoids linked to massive bee death all over the world.

Their properties clearly show that they should be classified as neonicotinoids.

General conclusion
This factsheet has demonstrated how pesticide companies make use of pseudo-science to give their new pesticides a more positive image. In the frame of the ever greater interest of the general public in the relation between pesticide use and health damage, including bee health, the fact that pesticide companies themselves decide what category a pesticide belongs to, for mere regulatory or marketing purposes should not be authorised.
Sulfoxaflor and flupyradifurone are neonicotinoid insecticides. They should be treated accordingly by regulator, taking into account their systemicity and the harm they could cause to non-target organism

Because of this detailed factsheet, articles about these 2 chemicals will be under their own section of this page from now on. This is an important distinction because, as neonicotinoids are shown to have such a massive effects on pollinators, companies want to keep on  registering insecticides with the same mode of action without the bad press of calling them neonicotinoids. France, which banned many neonicotinoids, has recently approved those two because the regulators have been fooled. There is currently (November 2017) a campaign to ask for France to 'Ban all bee-killing pesticides!' Please consider signing and sharing.
