“…This hypothesis was recently tested in honey bee colonies headed by queens artificially inseminated with one or 12 drones and proved true for N. ceranae , with significantly higher prevalence levels detected in genetically similar colonies as compared to genetically diverse colonies (Desai and Currie, ). Interestingly, no significant differences between the two types of colonies were found for N. apis (Desai and Currie, ), which agrees with a previous study from Woyciechoski and Krol (). In conclusion, while all these studies represent first (but not comparable) attempts to address the role of honey bee variability in N. ceranae virulence, carefully designed cage and field infection assays with genetically characterized host and pathogen are required for a better understanding of their interaction.…”

“…While it remains to be demonstrated that variation among A. mellifera subspecies influences virulence of N. ceranae , it has been repeatedly shown that increased genetic diversity within a colony improves its resistance to a diverse array of diseases (Palmer and Oldroyd, ; Tarpy, ; Tarpy and Seeley, ; Seeley and Tarpy, ; Desai and Currie, ), supporting one of the hypothesis related with the evolution of polyandry (Hamilton, ).

Nosema ceranae is a hot topic in honey bee health as reflected by numerous papers published every year. This review presents an update of the knowledge generated in the last 12 years in the field of N. ceranae research, addressing the routes of transmission, population structure and genetic diversity. This includes description of how the infection modifies the honey bee's metabolism, the immune response and other vital functions. The effects on individual honey bees will have a direct impact on the colony by leading to losses in the adult's population. The absence of clear clinical signs could keep the infection unnoticed by the beekeeper for long periods. The influence of the environmental conditions, beekeeping practices, bee genetics and the interaction with pesticides and other pathogens will have a direct influence on the prognosis of the disease. This review is approached from the point of view of the Mediterranean countries where the professional beekeeping has a high representation and where this pathogen is reported as an important threat.

“…groups of bees who share the same father) with different susceptibilities to parasites and pathogens, potentially reducing their spread within the colony. For instance, honey bee colonies composed of more patrilines have lower prevalence of A. apis (Tarpy, 2003), N. ceranae (Desai & Currie, 2015) and P. larvae (Seeley & Tarpy, 2007). Likewise, the prevalence of the trypanosomatid C. bombi is reduced in genetically diversity colonies of experimentally inseminated bumblebee queens (Baer & Schmid-Hempel, 2003).…”

Abstract. 1. Bees are key pollinators and their widespread decline has raised considerable concerns regarding the sustainability of ecosystems and food production. Many environmental stressors do not directly kill bees, but they alter their physiology and behaviour, ultimately impacting colonies and populations.2. This review considers the impact of parasites and pathogens on bee cognition. 3. First the main parasites and pathogens of bees are described, as well as how they modify the foraging behaviour, learning and memory of their hosts.4. Next, the various defence mechanisms developed by bees to mitigate these effects at both the individual and collective levels are examined.5. Finally, there is a discussion on how integrating research on host parasites, animal behaviour and cognition will provide a more detailed assessment of the contribution of parasites and pathogens to declines in the bee population and help to inform constructive ecological interventions.

“…There is a need to invest in diverse kinds of research and to expect that future ecological surprises are inevitable. The possibility of the emergence of a new species of invasive varroa mite (Roberts et al 2015), changes in honey bee genetics over time and space (Desai and Currie 2015;Locke et al 2012), and the vagaries of economic and political instability (Moritz and Erler 2016) highlight the importance of maintaining an appreciation of the novelty and possibilities of the future.…”

Scientific narratives surrounding colony collapse disorder (CCD) are often played against one another. However, oppositional knowledge politics do not neatly segregate the materiality and causal properties of the ecological phenomena they represent. Thus the challenge with CCD is not just to describe the partisan character of how knowledge about it is socially produced. It is also about how to integrate these politics through their less antagonistic material ecologies. We review three dominant discourses underlying CCD and honey bee decline and present a synthesis that conveys how their socially embedded perceptions about ecological causality are more compatible. We invoke a theoretical framework from complexity theory to demonstrate how multiple kinds of ecological causality, from the identifiable and addressable to the more emergent and unpredictable, can align under conflicting policy positions. We argue that this continuum of ecological explanations is a more conciliatory framework for responding to CCD. It provides an alternative to the antagonistic politics that tend to reify and defend either a restrictive search for a singular cause, a paralyzing documentation of all possible permutations of CCD, or a return to a utopian agrarian past. Relating how ecological knowledge is socially produced can illuminate stakeholder positions and strategies. But it is also constructive to map out how the ecological suppositions underlying them relate and inform one under.
