Infection Cycle, Transmission Mechanisms, and Management of Nosema ceranae in Apis mellifera Colonies
Nosema ceranae is a recently described, widespread microsporidian parasite of Apis mellifera that has raised concerns as to whether it is contributing to increased colony losses. To better understand this parasite, investigations were made into the seasonality of infections, alternative …

The Epizootiology of Nosema Pyrausta (Paillot) in The European Corn Borer, Ostrinia Nubilalis, in Central Illinois
Nosema pyrausta (Paillot), a microsporidium, is a chronic pathogen of the European corn borer, Ostrinia nubilalis (Hubner). A four year study was conducted in Woodford County, Illinois, from 1980 through 1983 in order to elaborate the relationship between corn borer density and the incidence of N. …

The effects of environmental factors on honey bee morbidity
… bee disease. I use varroa destructor mite and nosema parasite infection levels as measures of honey bee health. Varroa is an important measure of honey bee health because it has been linked to increased overwintering colony losses (USDA 2013). Nosema has also been linked to higher overwintering …

The costs and benefits of resistance and tolerance behaviors against Varroa mite (Varroa destructor Anderson and Trueman) in honey bee (Apis mellifera L.)
… In a laboratory study, I showed that Nosema inoculation (with co-infections of N. ceranae and N. apis) suppressed the effectiveness of mite removal behavior within selected bees relative to unselected bees. N. ceranae was more abundant than N. apis. Bees with greater mite removal …

A Molecular Diagnostic Survey of Pathogens and Parasites of Honey Bees, Apis mellifera L., From Arkansas and Oklahoma
… A. mellifera pathogens and parasites: protozoans Nosema apis and N. ceranae; bacterial pathogens Spiroplasma apis and S. melliferum; Trypanosomatid parasites Crithidia mellificae and Lotmaria passim and the parasitic phorid fly Apocephalus borealis. A study including both migratory honey bee …

Plant secondary metabolites enhance survival and pathogen tolerance in the European honey bee: a structure-function study
… medicinal effects on honey bees infected with Nosema ceranae. Our findings provide a platform to identify plant secondary metabolites which can augment current management techniques to support the long-term sustainability of the apiculture industry.

A molecular phylogeny of the Microsporida
… two groups, Encephalitozoon and Vairimorpha/Nosema groups, form a monophyletic taxon. The molecular phylogenies were compared to the modern taxonomic systems of the microsporidia and used to examine the evolutionary patterns of a number of morphological and ecological character states.

Effects of nutrition on honey bee microbiology, disease occurrence, and hive growth
… for Varroa mites and microsporidian pathogen Nosema. While supplemental nutrition did not have an overall impact on hive health or gut microbiome, the gut microbiome present at the beginning of experiment correlated with hive survival, suggesting presence/abundance of bacteria present before …
