40 Percent of U.S. Honey Bee Colonies Lost This Year
USAgNet - 06/24/2019

This winter has seen one of the biggest honey bee die-offs in the U.S. on record, with 37 percent of managed honey bee colonies lost from October 2018 to April 2019.

Preliminary results from the Bee Informed Partnership show that the rate of honey bee colony loss was nearly 9 percentage points higher this winter compared to the average winter loss.

"These results are very concerning, as high winter losses hit an industry already suffering from a decade of high winter losses," Dennis vanEngelsdorp, Maryland entomology associate professor and Bee Informed Partnership president, said in a statement.

Bee experts from the University of Maryland, Auburn University, and other colleges reached their findings after surveying 4,700 beekeepers across the US, accounting for over 300,000 colonies, over the past 13 years.

While their research didn't look into the cause of this effect, there's a long reel of factors that are known to be bad news for bee populations. The first is pathogens and parasites, such as the Varroa mite or Israeli acute paralysis virus, which humans have limited control over. However, the second two factors are our responsibility: climate change and industrial agriculture, namely the use of pesticides and the destruction of habitat.

Concerns about the world's bees started to mount in 2006 when scientists noticed that many hives were experiencing what's now known as colony collapse disorder (CCD). Seemingly out of nowhere, the bulk of worker bees would ditch their queen and abandon the otherwise healthy colony. Oddly enough, the problem of CCD has decreased over the past few years; however, bees are still struggling against the intensification of agriculture worldwide.
