Nosema ceranae Escapes Fumagillin Control in Honey Bees
Fumagillin is the only antibiotic approved for control of nosema disease in honey bees and has been extensively used in United States apiculture for more than 50 years for control of Nosema apis. It is toxic to mammals and must be applied seasonally and with caution to avoid residues in honey. Fumagillin degrades or is diluted in hives over the foraging season, exposing bees and the microsporid...
متن کاملDoes fumagillin control the recently detected invasive parasite Nosema ceranae in western honey bees (Apis mellifera)?
Western honey bee (Apis mellifera) colonies in Nova Scotia, Canada were sampled in spring and late summer 2007 to evaluate efficacy of fumagillin dicyclohexylammonium (hereafter, fumagillin) against Nosema ceranae. Colonies treated with fumagillin in September 2006 (n=94) had significantly lower Nosema intensity in spring 2007 than did colonies that received no treatment (n=51), but by late sum...
متن کاملAsymmetrical coexistence of Nosema ceranae and Nosema apis in honey bees.
Globalization has provided opportunities for parasites/pathogens to cross geographic boundaries and expand to new hosts. Recent studies showed that Nosema ceranae, originally considered a microsporidian parasite of Eastern honey bees, Apis cerana, is a disease agent of nosemosis in European honey bees, Apis mellifera, along with the resident species, Nosema apis. Further studies indicated that ...
متن کاملInfectivity and virulence of Nosema ceranae and Nosema apis in commercially available North American honey bees.
Nosema ceranae infection is ubiquitous in western honey bees, Apis mellifera, in the United States and the pathogen has apparently replaced Nosema apis in colonies nationwide. Displacement of N. apis suggests that N. ceranae has competitive advantages but N. ceranae was significantly less infective and less virulent than N. apis in commercially available lineages of honey bees in studies conduc...
متن کاملPhysiological and Behavioral Changes in Honey Bees (Apis mellifera) Induced by Nosema ceranae Infection
Persistent exposure to mite pests, poor nutrition, pesticides, and pathogens threaten honey bee survival. In healthy colonies, the interaction of the yolk precursor protein, vitellogenin (Vg), and endocrine factor, juvenile hormone (JH), functions as a pacemaker driving the sequence of behaviors that workers perform throughout their lives. Young bees perform nursing duties within the hive and h...
