New Harvard Study Proves the Reason Why Bees Are Dying

The human species is really starting to feel the consequences of their actions. One area we are waking up to is the massive amount of pesticides we spray (especially in North America) on our food that has not only been linked to human disease, but a massive die off in the global bee population within the past few years.

A new study out of Harvard University, published in the June edition of the Bulletin of Insectology puts the nail in the coffin, neonicotinoids are killing bees at an exponential rate, they are the direct cause of the phenomenon labeled as colony collapse disorder (CCD). Neonicotinoid’s are the world’s most widely used insecticides. (1)

“The results from this study not only replicate findings from the previous study, but also reinforce the conclusion that the sublethal exposure to neonicotinoids is likely the main culprit for the occurrence of CCD.” (1)

For this study, researchers examined 18 bee colonies at three different apiaries in central Massachusetts over the course of a year. Four colonies at each apiary were regularly treated with realistic doses of neonicotinoid pesticides, while a total of six hives were left untreated. Of the 12 hives treated with the pesticides, six were completely wiped out.

Neonicotinoids insecticides, persist in “extremely high levels” in planter exhaust material produced during the planting of crops treated with these insecticides. This runs contrary to industry claims that the chemicals biodegrade and are not a threat. These pesticide components are found in soil, they are also found in fields where the chemicals are not even sprayed.  

Bees also actively transfer contaminated pollen from primarily pesticide treated corn crops and bring it back to their hives. Furthermore, bees transfer these pesticides to other plants and crops that are not treated with the chemicals, which goes to show just how persistent these chemicals truly are in the environment. 

There has been an enormous amount of research which shows that our current regulations which protect the creatures that pollinate much of our food is extremely inadequate. It’s been published in a number of peer-reviewed journals showing how widely used pesticides have a very damaging effect on bees.

A paper published in the journal Nature discusses how bees are twice as likely to die when exposed to pesticides; two-thirds of the bees are lost when exposed compared to a third when not exposed. The exposed bees are also half as successful in gathering food. (2)

Scientists from the US Department of Agriculture as well as the University of Maryland published a study that linked chemicals, including fungicides, to the large scale die-off of bees that has recently plagued the planet, you can read that study here. 

In the United Stats alone, the honey bee population declined by approximately 30 percent, with some beekeepers reporting losses up to 90 and 100 percent. More than 100 US crops rely on honey bees to pollinate them.
