Partially Africanized bees found in eastern Tennessee!

VONORE, Tennessee – Tennessee’s first case of partially Africanized bees was confirmed through genetic testing last week in a colony belonging to a beekeeper in Monroe County. The colony has been depopulated and the Tennessee Department of Agriculture is working with beekeepers in the area to determine if other bees could have been affected.

State Apiarist, Mike Studer, says it is no surprise that partially Africanized bees have made their way to Tennessee considering they have already been found in other states such as Texas, Georgia, Mississippi and Florida. “I’m actually surprised it’s just now happening. We have been expecting this for some time,” Studer said. “Citizens need to be vigilant, but there’s no need to overreact. This is a situation that can be effectively managed through good beekeeping practices.

“We will be working with beekeepers to monitor their hives and to look for any signs of other aggressive bees in the area.”

Test results show that genetically, the bees were less than 17 percent Africanized, far less than the 50 percent considered by USDA to be truly Africanized. The bee colony was purchased by the beekeeper last year from an out-of-state dealer.

The most important difference between an Africanized honey bee and our domestic European honeybee is their behavior. Africanized bees are much more aggressive, defend their nests more fiercely and in greater numbers and are more likely to defend the nest when threatened by predators or adverse environmental conditions. But, the sting from a single Africanized bee is no more venomous than a European honey bee.

Africanized bees tend to colonize in smaller spaces than the docile European honeybee. Therefore, if you see honeybees in the ground, or in small openings such as flower pots or bluebird houses leave them alone and call the state apiarist immediately to assess the situation. Bees do not try to hurt people, they simply defend their territory.

If you do disturb an Africanized honeybee colony, follow these steps to protect yourself.

1. Run.

2. Cover your head with your shirt or jacket while running because Africanized bees tend to sting the face and head.

3. Never stand still or get boxed into a place outdoors where you cannot escape the attack.

4. Seek immediate shelter in an enclosed building or vehicle. Isolate yourself from the bees.

5. Do not attempt to rescue a victim without the proper protective gear and training. Doing so could make you the second victim.

State law requires all beekeepers register their colonies with the TDA and to update their registration every three years. Once registered, the state apiarist is able to contact beekeepers in the event of a disease outbreak or aerial pesticide spraying in their area. Registration also gives the beekeepers the opportunity for free inspections to make sure their colonies are healthy. Registration can be done online.

Entomological tests have confirmed that Africanized honeybees were responsible for the death of an elderly man in Dougherty County last week. News reports say the man accidentally disturbed a feral colony of bees with his bulldozer and that he received more than 100 stings.

“This is the first record of Africanized honeybees in Georgia,” said Agriculture Commissioner Tommy Irvin.

Africanized honeybees are a hybrid of African and European honeybees. Because of their extremely defensive nature regarding their nest (also referred to as a colony or hive), they are sometimes called “killer bees.” Large numbers of them sometimes sting people or livestock with little provocation.

The Africanized honeybee and the familiar European honeybee (Georgia’s state insect) look the same and their behavior is similar 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, Africanized honeybees are less predictable and more defensive than European honeybees. They are more likely to defend a wider area around their nest and respond faster and in greater numbers than European honeybees.

Africanized honeybees first appeared in the U.S. in Texas in 1990. Since then they have spread to New Mexico, Arizona, California, Nevada, Utah, Oklahoma, Arkansas, Louisiana, Florida and now Georgia. Entomologists and beekeepers have been expecting the arrival of these bees in Georgia for several years. There has been an established breeding population in Florida since 2005.

Because Africanized honeybees look almost identical to European honeybees, the bees from the Dougherty County incident had to be tested to accurately ascertain they were the Africanized strain. The Georgia Department of Agriculture sent samples of the bees to the Florida Department of Agriculture and Consumer Services which has the capability to do FABIS (fast African bee identification system) testing and the U.S. Department of Agriculture identification test (the complete morphometrics test) to confirm the bees’ identity.

Africanized honeybees are the result of an experiment that went awry in Brazil in the 1950s. Researchers were trying to create a honeybee better suited to tropic conditions. A few of the African bees escaped and began hybridizing with European honeybees. The hybrid “Africanized” honeybees (so named because they get their extremely defensive nature from the African honeybee) began colonizing South America and Central America, then Mexico and the U.S.

“Georgia beekeepers are our first and best line of defense against these invaders. They are the ones who will be able to monitor and detect any changes in bee activity,” said Commissioner Irvin.

“The Georgia Department of Agriculture is going to continue its trapping and monitoring of bee swarms to try to find where any Africanized honeybees are,” said Commissioner Irvin. “We also want to educate people about what to do in case they encounter a colony of Africanized honeybees. Georgians can visit our website for more information. The University of Georgia Cooperative Extension Service has a publication on Africanized honeybees that is available online (http://pubsadmin.caes.uga.edu/files/pdf/B%201290_2.PDF) or at Extension offices.”
