Africanized Honey Bee

San Bernardino County

Helendale

In July 1998, University of California, Davis, researcher Dave Nielsen found AHB foraging on roadside plants while sampling bees for AHB mitotype research in southern California. The bees were found at two different locations about four miles apart along National Trails Highway, near Vista Road and at Indian Trail.

Oro Grande

In the small town of Oro Grande about 12 miles away from the other two find sites, Nielsen found AHB, also foraging on roadside plants. All three of these find sites are outside the AHB colonized area of California. The AHB colonized area in California has been expanded to cover these areas.

The new AHB colonized area is approximately 25,030 square miles and includes all of Imperial County and parts of Riverside, San Bernardino and San Diego Counties.

CDFA Insect Biosystematist Tom Eichlin confirmed the determination based on mtDNA analysis performed by Scott Kinnee.
