Georgia man's death confirms presence of Africanized honeybees

Last week’s death of an elderly Dougherty County man has been attributed to Africanized honeybees. This fatality confirms the bees’ arrival in Georgia, according to the Georgia Department of Agriculture.
“The victim was operating a tractor and mower, aggravated a nest of bees and received more than 100 stings,” said Keith Delaplane, a University of Georgia Cooperative Extension entomologist.

Africanized honeybees have been in the United States since October 1990 when they were found in Texas. In 2005, they were confirmed in Florida.

European cousin essential to crops

A sub-species of honeybee, Africanized honeybees can interbreed with the European honeybee that is well known throughout Georgia as an important pollinator and producer of honey. One-third of American diets contain food crops that rely on European honeybees for pollination, according to the Georgia DOA.

Africanized and European honeybees look and behave alike in some respects. Each bee can sting only once, and there is no difference between Africanized honeybee venom and that of a European honeybee.

However, “the African variety is extremely defensive and responds with a massive stinging reaction with little provocation,” Delaplane said.

Don't swat, run, get inside and stay inside

The UGA honeybee expert urges the public to become aware of how to react if Africanized honeybees attack. He offers the following lifesaving tips:

1. Be cautious around places where Africanized honey bees are likely to nest, such as abandoned sheds, bee hive equipment, discarded tires and underground cavities.
2. If you are attacked, RUN AWAY. “You may think this sounds silly, but experience has taught us that people don’t run away,” he said. “Instead, they stand and swat, which simply escalates the defensive frenzy until it reaches lethal proportions.”
3. Get inside a closed vehicle or building as fast as possible, and STAY there. “Here’s another hard lesson we’ve learned. People don’t stay inside a closed vehicle if a few bees follow them inside,” Delaplane said. “Instead, they panic and flee back outside where tens of thousands of angry bees attack them."
This pattern has repeated itself over and over in the stinging incidents entomologists have monitored in Latin America and the southwestern U.S., he said. "The lesson is, don't worry about the few bees that follow you indoors. Get inside, and stay inside."
4. European honeybees and beekeepers are our best defense against Africanized honeybees. “Some communities may be considering zoning restrictions against all forms of beekeeping. This essentially cedes territory to the enemy. Only gentle European bees can genetically dilute the defensive Africanized variety,” he said.

First aid tips

If stung, the Georgia DOA says to follow these steps:

• Scrape – do not pull – stingers from skin as soon as possible. Pulling the stinger out will likely cause more venom to be injected into the skin.
• Wash sting area with soap and water.
• Apply ice for a few minutes to relieve pain and swelling.
• Seek medical attention if your breathing is troubled, if you’re stung numerous times or if you’re allergic to bee stings.
