Artificial Insemination Could Breed Better Bee

Rosanne Skirble
Honeybees are in trouble. Each year since 2006, one-third of their hives have been wiped out by a mysterious disease called Colony Collapse Disorder.

While experts aren't certain, they believe poor hive management, overworked bees, pesticides or parasitic mites could be to blame.

A beekeeper in Frederick, Maryland, is working on breeding a queen bee that can help her hive withstand the assault.

Breeding a better bee

Adam Finkelstein manages to keep his small operation healthy. He keeps some 200 hives not far from Washington, D.C..

His bees spend the winter in hives which are naturally insulated with honey to keep them warm in the coolest months. This time of year, the bees have begun their daily sorties to collect nectar.

Finkelstein has five bee yards at the core of his breeding program.  “We’re testing for yield, gentleness, the ability to get through the winter, the ability to build up in the spring, the ability to make honey and the ability to be thrifty and to keep alive during periods when there is no food.”

His major focus is on breeding a stronger queen resistant to the varroa mite, a parasite originally from Asia that carries viruses into the hive and has become a major problem for beekeepers in the U.S. and elsewhere. 

“Our bees handle this mite just fine and produce honey and can pollinate and can make more bees and that’s our goal and we’re getting there,” he says.

Artificial insemination

Finkelstein says breeding is a work in progress. He uses artificial insemination, which allows him to select desirable traits from both male and female. 

The procedure isn’t difficult, he says, but takes practice and patience. Working from his home laboratory, he first sedates the queen using carbon dioxide.

“While she is anesthetized, we use a very small set of instruments to position a syringe and deliver a known quantity of semen," he says. "And that’s it. She’s mated.”

Pesticide-free operation

Finkelstein tests his queens in his many hives. Once he's evaluated their traits, he sells them, making room for new queens.

He maintains a pesticide-free operation, unlike most commercial producers who depend on chemical treatments to keep their bees healthy.

“However, eventually, if the treatments fail to work or if the level of toxicity in the wax in the beehives becomes so great and the queens are not fertile," he says, "then those folks will probably turn towards a hardier, more mite tolerant queen choice.”

Finkelstein happily says a few of those bigger operations have begun to collaborate with him, recognizing that the future of beekeeping may not be about the next best pesticide, but about queens bred to produce offspring that can resist pathogens.

This person from Oregon is misguided. Mr. Finkelstein is breeding and incorporating genetics from bees who have done well in the colder climates. He is using stock bees from Minnesota. You should read some of the blogging he posts in other forums about his work. Your tone is rude and judgmental and colony collapse is not because of the invasion of the Africanized bee.

Why does it have to be something mysterious? Think that the native bees and non-commercial european bee hives in the north part of the country are doing well because of something unusual?
The reason for colony collapse is the invasion of the Africanized bee. It cannot handle temperatures of 32 or below for more than a few minutes.

By 2000, our entire southern tier states had the Africanized bee mixed with european bees. They exported these to others states. When there was a freeze, or when winter set in, the colonies died off. The weather has sharply cooled off since 2003 and the africanized bee does not do well in it.

Compare that with forest populations of european bees in our northern states. They are doing quite well. Our native pollinators are doing well, despite varroa and tracheal mites (which have been around for millennia). Its' possible to count 9 native bee types here in the northwest ranging from 1/8" long to 2" long, just by going out in a garden or flower garden for ten minutes. It's not like pesticides and other chemicals were not used like water here, just as every other place in the country.

So why not simply deal with the real reason for the commercial colony collapses, instead of the unscientific hysteria stuff?

Video Iran-Saudi Rivalry Is Stoking Conflict in Yemen

Iran has proposed a peace plan to end the conflict in Yemen, but the idea has received little support from regional rivals like Saudi Arabia. They accuse Tehran of backing the Houthi rebels, who have forced Yemen’s president to flee to Riyadh, and have taken over swaths of Yemen. As Henry Ridgwell reports for VOA, analysts say the conflict is being fueled by the Sunni-Shia rivalry between the two regional powers.
