A study of the yeast flora of 328 honey stomachs from 7 different pollinating bee species, and 342 flower nectar samples of 9 different flower species yielded 766 yeast isolates composed of 16 genera and 47 species. Most of the yeast species from both the sources belonged to the genusCandida, while the most frequently isolated yeasts wereDekkera intermedia from honey stomach andCandida blankii from flower nectar. Among the honey bees,Xylocopa sp., and among flowers,Citrus medica, yielded the… 

On the Trophic Niche of Bees in Cerrado Areas of Brazil and Yeasts in Their Stored Pollen

We studied eight species of meliponines native to the vast savanna and plateau area of “Cerrado” in central Brazil, where fire and human activities have removed over half of the natural habitat. We

Yeasts and filamentous fungi inhabiting guts of three insect species in Assiut, Egypt

Evaluating for the first time in Egypt the biodiversity of mycobiota that inhabit the guts of three insect species collected from Assiut Governorate found the number of taxa recovered from red-palm weevils and honey bees was almost equal, while lower number was isolated from beetles.

Species Richness of Yeast Communities in Floral Nectar of Southern Spanish Plants

Expected richness was higher for plant species-based than for nectar drop-based analyses, showing that the coverage of nectar yeast species occurring in the region would be improved by sampling additional host plant species.

Specialisation of Yeast Genera in Different Phases of Bee Bread Maturation

Starmerella (Candida) apis, a rarely isolated species, was the most frequent and abundant species in fresh bee bread and Yeasts from the bee’s honey stomach and from pollen pellets obtained from bees hind legs were dominated by Metschnikowia species.

Nectar yeasts of two southern Spanish plants: the roles of immigration and physiological traits in community assembly.

Nectarivorous Metschnikowia were not more resistant than other yeast species to plant secondary compounds and high sugar concentrations typical of nectar, but their higher growth rates may be decisive for their dominance in ephemeral nectar communities.

Do Honeybees Shape the Bacterial Community Composition in Floral Nectar?

It is concluded that the honeybees may introduce bacteria into the nectar and/or may be contaminated by bacteria introduced into theNectar by other sources such as other pollinators and nectar thieves.

Yeasts in floral nectar: a quantitative survey.

With yeasts being as ubiquitous and abundant in floral nectars as revealed by this study, and given their astounding metabolic versatility, studies focusing on nectar chemical features should carefully control for the presence of yeasts in nectar samples.

Nectar sugars and bird visitation define a floral niche for basidiomycetous yeast on the Canary Islands

A shift of floral visitors towards ornithophily alters the likelihood of yeast inoculation in flowers, and low concentrated hexose-dominant nectar promotes colonization of flowers by basidiomycetes, challenges the current understanding that nectar is an ecological niche solely occupied by ascomycetous yeasts.

Honey bees can disseminate a microbial control agent to more than one inflorescence pest of oilseed rape

Honey bees effectively transported the entomopathogenic fungus Metarhizium anisopliae to the flowers, causing infection and mortality of both adult and larval pollen beetles, as well as of adult seed weevils.

Four new species of yeast isolated from insect frass in bark ofTsuga heterophylla (Raf.) Sargent

Four new species of yeast were found in a study of the yeasts associated with insect frass underneath the bark of Tsuga heterophylla (the Pacific Coast hemlock) and it has been proposed to establish a “Candida parapsilosis Group” of species to which C. oregonensis was assigned.

An Analysis of the Yeast Flora Associated with Cactiphilic Drosophila and their Host Plants in the Sonoran Desert and Its Relation to Temperate and Tropical Associations

The genus Pichia is by far the most common yeast genus associated with Drosophila in all habitats analyzed (36% of 1,426 isolates); however, desert yeasts have similarities with yeasts of temperate trees.

Yeasts in greenhouse environment

SummaryThe examination of a total of 98 yeast cultures collected from the buds, the open flowers and the host animals of 8 different species of plants and from the related soils of the vessels in a

Four new, relatedCandida species from South African insect sources

Representatives of four new yeast species have been recovered from material of various Bostrichid, Cerambycid, Scolytid and Platypid beetle infestations in indigenous trees in the Transvaal, Natal and the Cape Province in South Africa.


Taxonomic studies on yeasts associated with bark beetles began when Beck (1922) described a new species of yeast, Endomyces bisporus, which she isolated repeatedly from the galleries of Ips typographus attacking spruce in Austria and was finally renamed Hansenula beckii (Beck) by Wickerham (1951).

Six new Candida species from South African insect sources

Representatives of six new yeast species have been recovered from material of various Bostrichid, Buprestid, Cerambycid, Platypid and Scoltyid infestations in indigenous trees in the Transvaal, Orange Free State, Natal and the Southern Cape Province.
