“…Given that our donor bees all came from a single, rare uninfected colony, we had a priori not expected any large variation in the impact of the virus. Possible reasons for this variation could be linked with seasonal factors, variation in the genetic compatibility with the host colonies, or subtle differences in the performance or health of the host colonies, such as the possible presence of Nosema among the host workers, which we did not explicitly look at, but which is known to cause precocious foraging and affect longevity, activity and out-of-hive performance of honeybees [13,45,58,76,77]. Alternatively, it is possible that the variation in DWV impact is linked to some of the control bees having become infected during the later stages of our experiment, which our treatment validation results suggest may have been the case (though likely at lower levels, figure 2), and that the speed at which this occurred differed across host colonies.…”

Several studies have suggested that covert stressors can contribute to bee colony declines. Here we provide a novel case study and show using radiofrequency identification tracking technology that covert deformed wing virus (DWV) infections in adult honeybee workers seriously impact longterm foraging and survival under natural foraging conditions. In particular, our experiments show that adult workers injected with low doses of DWV experienced increased mortality rates, that DWV caused workers to start foraging at a premature age, and that the virus reduced the workers' total activity span as foragers. Altogether, these results demonstrate that covert DWV infections have strongly deleterious effects on honeybee foraging and survival. These results are consistent with previous studies that suggested DWV to be an important contributor to the ongoing bee declines in Europe and the USA. Overall, our study underlines the strong impact that covert pathogen infections can have on individual and group-level performance in bees.

“…Although N. ceranae infection does not appear to alter the navigation and orientation of the honeybees while foraging, increased foraging duration and decreased flight frequencies have been reported in infected honeybees (Alaux et al, 2014;Dussaubat et al, 2013;Naug, 2014;Wolf et al, 2014). This decline in foraging efficiency is likely to be a result of imposed nutritional and energetic stress from infection (Aliferis et al, 2012;Martín-Hernández et al, 2011;Mayack & Naug, 2009;Mayack & Naug, 2010;Moffett & Lawson, 1975).…”

Host-pathogen coevolution leads to reciprocal adaptations, allowing pathogens to increase host exploitation or hosts to minimise costs of infection. As pathogen resistance is often associated with considerable costs, tolerance may be an evolutionary alternative. Here, we examined the effect of two closely related and highly host dependent intracellular gut pathogens, Nosema apis and Nosema ceranae, on the energetic state in Nosema tolerant and sensitive honeybees facing the infection. We quantified the three major haemolymph carbohydrates fructose, glucose, and trehalose using high-performance liquid chromatography (HPLC) as a measure for host energetic state. Trehalose levels in the haemolymph were negatively associated with N. apis infection intensity and with N. ceranae infection regardless of the infection intensity in sensitive honeybees. Nevertheless, there was no such association in Nosema spp. infected tolerant honeybees. These findings suggest that energy availability in tolerant honeybees was not compromised by the infection. This result obtained at the individual level may also have implications at the colony level where workers in spite of a Nosema infection can still perform as well as healthy bees, maintaining colony efficiency and productivity.

“…It is known that N. apis affects the epithelial cells lining the midgut of the adult bees (Bailey, 1955) and shortens the life span of both queens and adult bees (Wang & Moeller, 1970;Webster, 1994). Recent studies (Huang, Solter, Aronstein, & Huang, 2015;Natsopoulou, Doublet, & Paxton, 2015) suggest that N. ceranae is not more virulent than N. apis, in disagreement with older studies which suggested that it was associating it with colony depopulation and collapse (Hatjina et al, 2010;Higes et al, 2008;Paxton, 2010;Paxton et al, 2007) as well as colony losses in general, in particular in southern European countries (Botías, Martín-Hernández, Barrios, Meana, & Higes, 2013;Dussaubat et al, 2013;Globlirsch, Huang, & Spivak, 2013;Hatjina et al, 2011;Higes, Martín-Hernandez, & Meana, 2010, 2006Higes et al, 2005Higes et al, , 2008Soroker et al, 2011;Villa, Bourgeois, & Danka, 2013).…”

The long term effect of HiveAlive™, a commercial food supplement, was evaluated with respect to colony population size and Nosema ceranae spore loads. The supplement was administered in sugar syrup at a dose of 2.5 ml per liter of syrup to up to 20 colonies per group for a period of 2 years. Its use before and after winter increased a colony's worker population size by 89% and reduced Nosema ceranae spores by 57% compared to control colonies. These results represent the first-known hive manipulation to have a lasting effect on nosema spore levels. The positive effect of HiveAlive™ may have been a result of its continued use over a two-year period.Efectos a largo plazo del suplemento alimenticio HiveAlive TM sobre la fuerza de las colonias de abejas y el recuentos de esporas de Nosema ceranae El efecto a largo plazo de HiveAlive™, un suplemento alimenticio comercial, se evaluó con respecto al tamaño de la població n de la colonia y la carga de esporas de Nosema ceranae. El suplemento se administró en jarabe de azúcar a una dosis de 2,5 ml por litro de jarabe hasta 20 colonias por grupo en un período de dos años. Su uso antes y después del invierno aumentó el tamaño de la població n de obreras de una colonia hasta en un 89% y redujo las esporas de Nosema ceranae en un 57% en comparació n con las colonias de control. Estos resultados representan la primera manipulació n de las colmenas con un efecto duradero sobre los niveles de esporas de Nosema. El efecto positivo de HiveAlive™ puede haber sido resultado de su uso continuado durante un período de dos años.
