Feeding the hive with honey should be avoided as it can amplify the risk of infection spreading as well as attracting potential robber bees, which can carry diseases to the hive. [1] Clean water should be provided at all times. [1] There is no viable treatment against M. mellificae. Weak populations have a chance of self-recovery.
In Spanish honey bee populations, mtDNA haplotypes of African bee strains were found to be frequently present (Smith 1991, Garnery et al 1995) (Cornuet et al 1975, 1978, 1982, 1988; Ruttner 1988; Cornuet and Fresnaye 1989; Orante-Bermejos and Garcia-Fernandez 1995; Hepburn and Radloff 1996).
