“…Next-generation sequencing studies of fungal bee microbiota use short sequences that result in genus-level identification but do not allow reliable species-level identification (e.g., [ 24 , 25 ]). However, a yeast-species-dependent effect on bee fitness was recognised by the addition of different yeast species to artificial nectar fed to bumble bees [ 26 ]. Physiologically and ecologically different groups of yeasts may also be involved in pollen resources of honey bees with potentially different effects on bee fitness, and it seems appropriate to address the yeast diversity during the storage and maturation of bee bread by culture-based techniques.…”

Pollen stored by bees undergoes a fermentation marked by the presence of lactic acid bacteria and yeasts. It results in bee bread. Past studies have singled out Starmerella (Candida) magnoliae as the most common yeast species in honey bee-stored bee bread. Starmerella species are ecological specialists with potential biotechnological value. The rarity of recent studies on yeasts in honey bees prompted us to generate new information on yeast diversity during the conversion of bee-collected pollen to bee bread. Bees and stored pollen from two apiaries in Belgium were sampled, a yeast isolation protocol was developed, yeast isolates were grouped according to their macro- and micromorphology, and representative isolates were identified using DNA sequences. Most of the 252 identified isolates belonged to the genera Starmerella, Metschnikowia, and Zygosaccharomyces. The high abundance of yeasts in fresh bee bread decreased rapidly with the storage duration. Starmerella species dominated fresh bee bread, while mostly Zygosaccharomyces members were isolated from aged bee bread. Starmerella (Candida) apis, a rarely isolated species, was the most frequent and abundant species in fresh bee bread. Yeasts from the bee’s honey stomach and from pollen pellets obtained from bees hind legs were dominated by Metschnikowia species. The distinctive communities from pollen pellets over fresh bee bread to aged bee bread indicate a non-random distribution of these yeasts.

“…Differences were also observed for adults, since fruit flies fed S. cerevisiae have longer thoraxes and larger wings [ 107 ]. The presence of yeasts in the diet of the bumblebee B. terrestris also promotes colony development in terms of the number of pupae and workers [ 118 ]. However, such observation is species-dependent as Wickerhamiella bombiphila , Metschnikowia gruessii and R. mucilaginosa induced the strongest positive impact on the development of these bumblebee colonies [ 118 ].…”

“…Other mechanisms, such as resource competition or production of antimicrobial compounds (toxins or other), allow yeasts to inhibit colonization of the insect host by entomopathogens or human pathogens. An in vitro study has demonstrated that yeasts of the species M. reukaufii , S. bombi , W. bombiphila , previously isolated from the midgut of the bumblebee B. terrestris and known to be competitive for resource consumption reduce the development of the natural parasite of this insect (the protozoan Crithidia bombi ) by 25% to 85% [ 118 ].…”

Diversity and Functions of Yeast Communities Associated with Insects

Following the concept of the holobiont, insect-microbiota interactions play an important role in insect biology. Many examples of host-associated microorganisms have been reported to drastically influence insect biological processes such as development, physiology, nutrition, survival, immunity, or even vector competence. While a huge number of studies on insect-associated microbiota have focused on bacteria, other microbial partners including fungi have been comparatively neglected. Yeasts, which establish mostly commensal or symbiotic relationships with their host, can dominate the mycobiota of certain insects. This review presents key advances and progress in the research field highlighting the diversity of yeast communities associated with insects, as well as their impact on insect life-history traits, immunity, and behavior.

“…Rearing techniques for captive bumblebees are constantly being improved, with a focus on higher yields (i.e. the proportion of saleable colonies), faster colony development (Ribeiro et al ., 1996; Jie et al ., 2005; Gurel & Gosterit, 2008), and bumblebee health and disease management (Huang et al ., 2015; Graystock et al ., 2016; Bartomeus et al ., 2020; Pozo et al ., 2020). Maintaining optimal temperatures inside the nest is key for the successful development of brood in both wild and captive bumblebee colonies.…”

Thermoregulation, that is, the active control of temperature, is key to ensure proper brood development in both wild and captive bumblebee nests. In this study, thermoregulation dynamics were assessed relative to colony age and ambient temperature using commercially reared Bombus terrestris L. (Hymenoptera, Apidae, Bombus) colonies. We observed a positive relationship between brood and nest temperatures in response to ambient temperature. Thermoregulation investment (by either brooding or fanning) was lowest at brood surface temperatures between 33 and 34 °C and ambient temperatures between 28 and 32 °C. Brood temperature was less stable and thermoregulation investment higher in younger colonies, especially at lower ambient temperatures. Furthermore, queens initiated colonies sooner and colonies developed faster when kept at an ambient temperature of 29 °C as compared to 24 °C. Our results suggest that ambient temperatures are ideally kept between 29 and 31 °C.
