Bee’s Neonicotinoid Addiction May Lead to their Ultimate Extinction, Study

 A couple of new studies released Wednesday in Nature are irritating when taken independently, yet all the more chilling when laid out beside one another.

The principal study gives new proof that neonicotinoid bug sprays can have a negative impact on bees, adding weight to the hypothesis that these chemicals could add to colony collapse disorder and jeopardize our food supply.

In the second study, other researchers found that bees don’t maintain a strategic distance from these harmful pesticides.

While they are safe for people in the short term, a few studies have contended that they’re killing off bees on a scale so extensive that our sustenance security is debilitated.

In the first of the two most recent studies, scientists attempted to figure out if the negative impacts seen in bees presented to neonicotinoids in the lab can be recreated in this present reality.

While the study isn’t generally cursing for the pesticide, it shows that scientists will most likely be unable to anticipate how bees will respond to neonicotinoids utilizing only one species types.

Perhaps honey bees know to keep away from neonicotinoids? Not really, as indicated by Nature’s second new study.

At the point when given a choice between sugar and sugar blended with the pesticide – which tastes bitter, a taste researcher had trusted bees would keep away from – bees didn’t demonstrate any evidence that they could taste a distinction.

“Even worse, we now have evidence that bees prefer to eat pesticide-contaminated food. Neonicotinoids target the same mechanisms in the bee brain that are affected by nicotine in the human brain. The fact that bees show a preference for food containing neonicotinoids is troubling as it suggests that like nicotine, neonicotinoids may act like a drug to make foods containing these substances more rewarding. If foraging bees prefer to collect nectar containing neonicotinoids, this could have a knock-on negative impact on whole colonies and on bee populations.  And it could be a more normal nibble for bees than we’d already suspected. “

In an announcement for the Science Media Center, Linda Field, Head of Biological Chemistry and Crop Protection at Rothamsted Research, brought up that more confirmation would be expected to demonstrate that neonicotinoids were doing to bees what nicotine does to people.
