Glyphosate and Fungicides Attract Honey Bees To Them – Bee Decline
Turns out that Monsanto’s Big Ag weedkiller and fungicides might lure bees like….well, like a flower to a bee. And like a sweet poison…
Recently, we reported the a surprising culprit behind the bee decline might actually be fungicides. It does appear that fungicides were an overlooked poison to the bees and there might now be a connection. Just on the heels of this discover, we find more disturbing news…
The journal Scientific Reports states this alarming conclusion,
“When given the choice, honey bee foragers prefer to collect sugar syrup laced with the fungicide chlorothalonil over sugar syrup alone.”

Recent studies have linked fungicides to declines in honey bee and wild bee populations. One recent study, for example, found parallels between the use of chlorothalonil and the presence of Nosema bombi, a fungal parasite, in bumble bees. Greater chlorothalonil use also was linked to range contractions in four declining bumble bee species.
Other research has shown that European honey bees have a very limited repertoire of detoxifying enzymes and that exposure to one potentially toxic compound – including fungicides – can interfere with their ability to metabolize others.
“People assume that fungicides affect only fungi,” said University of Illinois entomology professor and department head May Berenbaum, who led the new research with postdoctoral researcher Ling-Hsiu Liao.
But fungi are much more closely related to animals than they are to plants. And toxins that disrupt physiological processes in fungi can also potentially affect them in animals, including insects.
Some scientists have argued that bees may be less susceptible to agricultural chemicals than laboratory studies suggest because the bees might detect potentially toxic chemicals in the environment and avoid them. But a 2015 study found that European honey bees and at least one species of bumble bee actually prefer food laced with neonicotinoid pesticides.
To test whether foraging honey bees showed a preference for other chemicals they are likely to encounter in the wild, Liao set up two feeding stations in a large enclosure.
Foraging honey bees could fly freely from one feeder to the other, choosing to collect either sugar 
syrup laced with a test chemical or sugar syrup mixed with a solvent as the control. Over the course of the study, she tested honey bee responses to nine naturally occurring chemicals, three fungicides and two herbicides at various concentrations.
The trials revealed that honey bees prefer the naturally occurring chemical quercetin over controls at all concentrations tested.
“That makes sense, because everything the honey bees eat has quercetin in it,” Berenbaum said. “There’s quercetin in nectar, there’s quercetin in pollen. Quercetin is in honey and beebread, and it’s a reliable cue that bees use to recognize food.”
Shocking Discovery of Preferred Food of Honey Bees – Monsanto Lies
To the researchers’ surprise, the bees also preferred sugar syrup laced with glyphosate – the active ingredient in Monsanto’s Roundup herbicide – at 10 parts per billion, but not at higher concentrations. And while the bees actively avoided syrup containing the fungicide prochloraz, they showed a mild preference for sugar syrup laced with chlorothalonil at 0.5 and 50 parts per billion, but not at 500 ppb.
“The bees are not only not avoiding this fungicide, they’re consuming more of it at certain concentrations,” Berenbaum said.
Fungicides are among the most prevalent contaminants of honey bee hives, and it is likely the bees themselves are bringing these pesticides into the colony through their food-collecting activities.
Why Would Honey Bees Collect Fungicides and Other Toxicants?
While perplexing, bees’ preferences for some potentially toxic chemicals may be the result of their distinct evolutionary history, Berenbaum said.
“Honey bee foragers are gleaners,” she said. “They’re active from early spring until late fall, and no single floral source exists for them for that whole season. If they don’t have a drive to search out something new, that’s going to seriously compromise their ability to find the succession of flowers they need. Unnatural chemicals might be a signal for a new food.”
The new findings are worrisome in light of research showing that exposure to fungicides interferes with honey bees’ ability to metabolize the acaricides used by beekeepers to kill the parasitic varroa mites that infest their hives, the researchers said.
“The dose determines the poison,” is the favored propaganda line of chemical corporations and their propagandists. The slogan forgets the toxic cocktail of multiple substances pollinators collect every day. Additionally, because of the pesticides’ and fungicides’ effect on the immune system of bees and their ability to metabolize these toxicants, the slogan actually fits in a horrific sense.
“The dose determines the poison,” Berenbaum said.
“If your ability to metabolize poisons is compromised, then a therapeutic dose can become a toxic dose. And that seems to be what happens when honey bees encounter multiple pesticides.”
