Marathon is a formulation of the neonic insecticide, imidacloprid, that’s commonly used on ornamental plants in nurseries, garden centers, and homes across the US. A 2021 University of California paper shows that the application of Marathon, even at 30% of the recommended dose, killed 90% of leafcutter bees.
Category: Neonics and bees
These posts look at the impact of the neonicotinoids (neonics) on the health of bees, other pollinators, and aquatic habitats.
Neonics are now the most widely used insecticides in the world – examples include imidacloprid, thiamethoxam, and clothianidin.
I tend to focus a lot on imidacloprid in these posts, because of its impact, widespread use and good research coverage. Imidacloprid alone constitutes one fifth of the global insecticide market. However, all of the neonics pose a threat to bees and other pollinators and to aquatic ecosystems.
Be aware that a majority of the crops grown in the US are treated with neonics. Choosing items that are specifically stated to be organic, regenerative, or pesticide-free is the best way to avoid neonics.
Risk-benefit analysis of Bayer’s imidacloprid
Bayer’s imidacloprid is one of the most widely used insecticides and belongs to a group of pesticides known as neonics (or neonicitinoids), which target insects’ nervous systems. Following extensive research I present a risk/benefit analysis for imidacloprid. Neonics are often used by default, for example as seed coatings, and yet offer no benefit in many cases. The risks, on the other hand, are sobering and demand immediate action.
Seresto flea collar & imidacloprid
Earlier in March, USA Today reported that bestselling Seresto flea collars have been linked to 1700 pet deaths in the US – and that’s just going by the number reported to the Environmental Protection Agency (EPA); the actual number is expected to be higher. The story originated from Johnathan Hettinger at the Midwest Center for … Continue reading Seresto flea collar & imidacloprid
The EU bans neonics. What will the US do?
the EU has voted to ban neonics (neonicotinoids) in Europe, putting a more permanent stamp on the temporary ban that had been in place since 2013. Will the US follow suit?
The subtle effects of neonics on bees
The subtle effects of neonics on bees is the topic of this third post looking at the connection between the use of neonics (neonicotinoids) in agriculture and bee health. I'm a research scientist and have no agenda here, other than uncovering the truth. In parts one and two I’ve focused on the toxicity of the … Continue reading The subtle effects of neonics on bees
Examination of evidence that neonicotinoids are safe for bees
In this post I will examine a case often cited by Bayer & Co. as evidence that neonicotinoids are safe for bees. This is part two of an impartial investigation into whether neonicotinoids (neoincs) are harmful to honey bees. I have nothing to gain from a position on either side of this debate and have … Continue reading Examination of evidence that neonicotinoids are safe for bees
