Hockley and Cochran counties were added Friday to the state quarantine, restricting the movement of commercial bee operations following the detection of Africanized honey bees.
The addition makes 136 counties in Texas now quarantined for Africanized honey bees, according to John Fick, assistant chief inspector for the Texas Apiary Inspection Service, a unit of the Texas Agricultural Experiment Station.
A sample of bees taken from managed hives were analyzed and found to be Africanized.
The quarantine allows beekeepers to move beehives within, but not out of, the zone in an effort to prevent assisting the spread.
Africanized honey bees look just like regular domestic honey bees but are more defensive in protecting their hives.
State bee inspectors continue to monitor a series of bee traplines that extend across the state from Louisiana to New Mexico.
The Africanized bee was first detected in the United States near Brownsville in October 1990. Since then, the bee has spread through much of the state, along a line roughly from south of Houston to Lubbock to El Paso. Africanized honey bees also have been found in Arizona, California, Nevada and New Mexico.
