American honeybee colonies are dying at a rate of 2 out of 5 last year, with the most deaths occurring during the summer, the US federal survey said.
Since April 2014, beekeepers have lost 42.1 per cent of their colonies, the second-highest rate in nine years, according to an annual survey conducted by a bee partnership that includes the U.S. Department of Agriculture.
Though it may sound dire, but in reality is is not. After a colony dies, beekeepers split the left colonies, start a new one, and the colonies propagate again, wrote study co-authors Keith Delaplane from Univ. of Georgia and Dennis vanEngelsdorp from the Univ. of Maryland.
But what bothered entomologists is that they have noticed that a lot of bees were dying more in summer than during winter, vanEngelsdorp stated. The study revealed that the bee colonies died at a rate of 27.4 % this summer, an increase of 19.8% compared to the prior summer.
Since April 2014, the state of Wisconsin, Pennsylvania, Oklahoma, Maryland, Maine, Iowa, Illinois and Delaware witnessed 60% of bees dying, the survey said.
Elements like poor nutrition, pesticides, and mites are blamed for the death of bees.
Chief beekeeper Dick Rogers of Bayer, the pesticide-maker, said the figure is “nothing unusual at all” and said the study exhibited a production of more colonies. From 2.64 million in the year 2014 to 2.74 million bees in 2015. But that does not equate an improved or stable health of bees, said vanEngelsdorp.
