SCIENCE IN THE NEWS - Honeybees Are Disappearing, No One Knows Why

作者:Marsha James 发布日期:8-24-2015

Honeybees are disappearing, and no one knows exactly why. Entomologists and scientists around the world are scrambling to find the answer to colony collapse disorder.
Honeybees are disappearing, and no one knows exactly why. Entomologists and scientists around the world are scrambling to find the answer to colony collapse disorder.

Entomologists -- scientists who study insects -- are working with other scientists to learn why bee colonies are dying in the United States. They call the problem "colony collapse disorder."

VOA recently spoke with amateur beekeepers in Fort Wayne, Indiana who are working to learn about honeybees and how to keep them alive.

Bees are needed to produce one third of our food. That is why Megan Ryan is worried about their survival. Earlier this year, she created an apiary, a place where groups, or hives, of honeybees are kept.

"Our hives are full of what's called Italian honeybees."

Italian bees are popular because they are not as aggressive as other kinds of bees. And they reproduce faster than other kinds of honeybees. In just four months, the apiary has grown from 10,000 to 70,000 bees in each hive.

Alex Cornwell is also a beekeeper. He says over the past ten years, both American and European hives have lost more than one fourth of their population.

"It's unknown what colony collapse disorder is caused by specifically, but it could be a combination of anywhere from pesticides to mites to pathogens."

Every time they visit the apiary, Ms. Ryan and Mr. Cornwell record information about the bees.

"We would share it with the DNR (Department of Natural Resources), other beekeepers -- any conservation effort, any organization that would like our records we freely share those."

They also teach people about beekeeping. They want people to begin their own hives.

"You don't have to be a scientist that has a degree in order to teach people and help people learn about bees and that's the awesome part about beekeeping -- anybody can do it."

About 100 people have said they want to learn more about creating their own hives. Ms. Ryan and Mr. Cornwell say they will start a program to teach migrant workers about beekeeping so they can take that knowledge with them wherever they work.
