Honey Bee Health

The USDA Bee Disease Diagnosis Service Located at the United States Department of Agriculture (USDA)  Beltsville Agricultural Research Center in Beltsville, Maryland, the lab offers a free service for diagnosing diseases in bees.

The diagnosis of bee diseases has been a focus of this laboratory since its inception in 1891 and they operate a “Bee Disease Diagnosis Service” for beekeepers across the U.S. There is no charge for this service.Samples received of adult bees and beeswax comb (with and without bee brood) are examined for bacterial, fungal and microsporidian diseases as well as for two species of parasitic mites and other pests associated with honey bees (i.e., small hive beetle, Aethina tumida).

When requested, American foulbrood samples are cultured and isolates are screened for their sensitivity to Terramycin (oxytetracycline) and Tylan (tylosin).
