Honey Bees Attracted to Glyphosate and a Common Fungicide

Animals

By Dan Nosowitz

All species evolve over time to have distinct preferences for survival. But with rapidly changing synthetic chemicals, sometimes animals don't have a chance to develop a beneficial aversion to something harmful.


New research from the University of Illinois indicates that honey beeswhich are dying en masse—may actually prefer the taste of flowers laced with pesticides that are likely harmful. The study tested honey bee consumption of different sugar syrups, some plain and some with different concentrations of common pesticides. They found that while the bees didn't care for syrup with extremely high concentrations of pesticides, at low levels, the bees flocked to those pesticides.

Among the pesticides tested were the ever-controversial glyphosate, the most common pesticide in the U.S., which previous studies have also shown to be attractive to honey bees. Chlorothalonil, which is ranked as the 10th most commonly used fungicide in the U.S., usually on peanuts and potatoes, also proved to attract more honey bees. (The connection between fungicides and honey bee health is not that clear; studies suggest they are not in themselves highly toxic, but in combination with other factors can be dangerous).

The bees did not universally prefer adulterated syrups; the researchers note that they avoided prochloraz, a fungicide sold under the name Sportak. And of course, laced sugar syrup is not the same as a flower in the wild. Still, it's another alarming bit of news about our bees.

Fires in the Brazilian Amazon have jumped 84 percent during President Jair Bolsonaro's first year in office and in July 2019 alone, an area of rainforest the size of Manhattan was lost every day. The Amazon fires may seem beyond human control, but they're not beyond human culpability.

Why are you publishing this book now?

I still feel that the way that we talk about climate change is too compartmentalised, too siloed from the other crises we face. A really strong theme running through the book is the links between it and the crisis of rising white supremacy, the various forms of nationalism and the fact that so many people are being forced from their homelands, and the war that is waged on our attention spans. These are intersecting and interconnecting crises and so the solutions have to be as well.

Drivers of electric cars are being unfairly punished by punitive fees in several states, according to a newly published analysis by Consumer Reports. Legislators in 26 states have enacted or proposed special registration fees for electric vehicles (EVs) that the consumer advocacy group found to be more expensive than the gas taxes paid by the driver of an average new gasoline vehicle.
