Africanized Honey Bee

San Diego County

Jacumba

University of California, Davis, researcher Dave Nielsen found AHB while sampling bees for AHB mitotype research in southern California. The bees were found foraging on roadside plants along I-8 at the Jacumba exit. The find site is outside the AHB colonized area of California. The AHB colonized area in California has been expanded to cover this area.

The new AHB colonized area is approximately 23,030 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.
