Individual Variability of Nosema ceranae Infections in Apis mellifera Colonies
Since 2006, beekeepers have reported increased losses of Apis mellifera colonies, and one factor that has been potentially implicated in these losses is the microsporidian Nosema ceranae. Since N. ceranae is a fairly recently discovered parasite, there is little knowledge of the variation in infection levels among individual workers within a colony. In this study we examined the levels of infec...
متن کاملPopulation Genetics of Nosema apis and Nosema ceranae: One Host (Apis mellifera) and Two Different Histories
Two microsporidians are known to infect honey bees: Nosema apis and Nosema ceranae. Whereas population genetics data for the latter have been released in the last few years, such information is still missing for N. apis. Here we analyze the patterns of nucleotide polymorphism at three single-copy loci (PTP2, PTP3 and RPB1) in a collection of Apis mellifera isolates from all over the world, natu...
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 کاملEffects of Nosema apis, N. ceranae, and coinfections on honey bee (Apis mellifera) learning and memory
Western honey bees (Apis mellifera) face an increasing number of challenges that in recent years have led to significant economic effects on apiculture, with attendant consequences for agriculture. Nosemosis is a fungal infection of honey bees caused by either Nosema apis or N. ceranae. The putative greater virulence of N. ceranae has spurred interest in understanding how it differs from N. api...
متن کاملAfrican Honey Bees (apis Mellifera Scutellata) and Nosema (nosema Apis) Infections
Nosema apis has been found on all continents where there is beekeeping using Apis mellifera. However, there is very little data on the prevalence and impact of Nosema apis in honey bee colonies in tropical climates and it may be uncertain if all records of Microsporidia in honey bees actually are records of the same parasite. Also, the development of N. apis has not been documented in tropical ...
