Infectivity 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 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 کاملIntraspecific Aggression in Giant Honey Bees (Apis dorsata)
We investigated intraspecific aggression in experimental nests (expN₁, expN₂) of the giant honey bee Apis dorsata in Chitwan (Nepal), focusing on interactions between surface bees and two other groups of bees approaching the nest: (1) homing "nestmate" foragers landing on the bee curtain remained unmolested by guards; and (2) supposed "non-nestmate" bees, which were identified by their erratic ...
متن کاملExtensive population admixture on drone congregation areas of the giant honeybee, Apis dorsata (Fabricius, 1793)
The giant honeybee Apis dorsata often forms dense colony aggregations which can include up to 200 often closely related nests in the same location, setting the stage for inbred matings. Yet, like in all other Apis species, A. dorsata queens mate in mid-air on lek like drone congregation areas (DCAs) where large numbers of males gather in flight. We here report how the drone composition of A. do...
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...
