TLDR
The data show that DWV, Nosema ceranae, Varroa destructor and Vitellogenin can be predictive markers for winter colony losses, but their predictive power strongly depends on the season.Abstract:
Across the Northern hemisphere, managed honey bee colonies, Apis mellifera, are currently affected by abrupt depopulation during winter and many factors are suspected to be involved, either alone or in combination. Parasites and pathogens are considered as principal actors, in particular the ectoparasitic mite Varroa destructor, associated viruses and the microsporidian Nosema ceranae. Here we used long term monitoring of colonies and screening for eleven disease agents and genes involved in bee immunity and physiology to identify predictive markers of honeybee colony losses during winter. The data show that DWV, Nosema ceranae, Varroa destructor and Vitellogenin can be predictive markers for winter colony losses, but their predictive power strongly depends on the season. In particular, the data support that V. destructor is a key player for losses, arguably in line with its specific impact on the health of individual bees and colonies.read more

TL;DR: The loss rate in the winter of 2015–2016 was amongst the lowest winter losses recorded over the ten years this survey has been conducted, but 59.0% (n = 3378) of responding beekeepers had higher losses than they deemed acceptable.

Bees under stress: sublethal doses of a neonicotinoid pesticide and pathogens interact to elevate honey bee mortality across the life cycle

TL;DR: Common microbial pathogens appear to be major threats to honey bees, while sublethal doses of pesticide may enhance their deleterious effects on honey bee larvae and adults and it remains an open question as to whether these interactions can affect colony survival.
Journal ArticleDOI
Varroa-virus interaction in collapsing honey bee colonies.
TL;DR: In colonies where varroa treatment reduced the mite load, colonies overwintered successfully, allowing the mites and viruses to be carried over with the bees into the next season, and in the untreated control group, titres increased most dramatically.

TL;DR: The results from the eighth annual survey on winter losses and the second annual survey of summer and annual losses show total winter loss was one of the lowest reported in 8 years, and 66 % of all beekeepers had higher losses than they deemed acceptable.

Physiological and Behavioral Changes in Honey Bees (Apis mellifera) Induced by Nosema ceranae Infection
TL;DR: The effects of infection with a recent honey bee pathogen on physiological factors underlying the division of labor in workers are investigated and disruption of the basic underpinnings of temporal polyethism due to infection may be a contributing factor to recent high colony mortality, as workers may lose flexibility in their response to colony demands.

TL;DR: The observation that irradiated combs from affected colonies can be repopulated with naive bees suggests that infection may contribute to colony collapse disorder (CCD).

TL;DR: This is the first comprehensive survey of CCD-affected bee populations that suggests CCD involves an interaction between pathogens and other stress factors, and presents evidence that this condition is contagious or the result of exposure to a common risk factor.

TL;DR: It is suggested that an implied reduction in immune flexibility in bees reflects either the strength of social barriers to disease, or a tendency for bees to be attacked by a limited set of highly coevolved pathogens.
