“…According to the review by Tehel et al (2016), 17 species of bees, including one species in the genus Ceratina, have been described as positive for DWV. In our study, detection of DWV in C. smaragdula was associated only with Varroa-positive areas, where one out of four small carpenter bees sampled tested positive for the virus.…”

“…So far, DWV has been detected in 23 insect genera across Europe, North and South America (Guzman-Novoa et al, 2015;Levitt et al, 2013;Reynaldi et al, 2013;Singh et al, 2010), including social and non-social bees, wasps, ants, and a myriad of other insect groups. Not much is known about the impact of the virus in these host species (Tehel et al, 2016). Negative strands of DWV, suggestive of viral replication in the host, have been found only in 5 genera of non-Apis insects (Levitt et al, 2013;Tehel et al, 2016).…”

Negative strands of DWV, suggestive of viral replication in the host, have been found only in 5 genera of non-Apis insects (Levitt et al, 2013;Tehel et al, 2016). However, the discovery of DWV among a wide range of species has created concerns about a possible "viral spillover" from honey bee colonies to other insect species, especially economically important pollinators such as bumble bees (Graystock et al, 2016a, Graystock et al, 2016b.…”

“…destructor is present and DWV is prevalent in the honey bee population (Budge et al, 2015;Tehel et al, 2016;Traynor et al, 2016). In fact, the presence of V. destructor in honey bee colonies has been linked to increased viral loads, virulence, and prevalence of DWV in honey bee populations (Martin et al, 2012).…”

“…Re-emerging viral diseases such as DWV represent one of the major threats to honey bee health, and the "spillover" of pathogens to wild bees and other insects may also contribute to the current global pollinator decline (Fürst et al, 2014;Genersch et al, 2006;Graystock et al, 2013a;Graystock et al, 2013b;Manley et al, 2015;Tehel et al, 2016). Here we carry out a preliminary comparison of the incidence of DWV on non-Apis insects in areas with and without V. destructor.…”

Abstract:Varroa destructor, a parasitic mite of honey bees, is also a vector for viral diseases. The mite displays high host specificity and requires access to colonies of Apis spp. to complete its lifecycle. In contrast, the Deformed Wing Virus (DWV), one of the many viruses transmitted by V. destructor, appears to have a much broader host range. Previous studies have detected DWV in a variety of insect groups that are not directly parasitized by the mite. In this study, we take advantage of the discrete distribution of the Varroa mite in the Hawaiian archipelago to compare DWV prevalence on non-Apis flower visitors, and test whether Varroa presence is linked to a "viral spillover". We selected two islands with different viral landscapes: Oahu, where V. destructor has been present since 2007, and Maui, where the mite is absent. We sampled individuals of Apis mellifera, Ceratina smaragdula, Polistes aurifer, and Polistes exclamens, to assess and compare the DWV prevalence in the Hymenoptera community of the two islands. The results indicated that, as expected, honey bee colonies on Oahu have much higher incidence of DWV compared to Maui. Correspondingly, DWV was detected on the Non-Apis Hymenoptera collected from Oahu, but was absent in the species examined on Maui. The study sites selected shared a similar geography, climate, and insect fauna, but differed in the presence of the Varroa mite, suggesting an indirect, but significant, increase on DWV prevalence in the Hymenoptera community on mite-infected islands.

Bee parasites are the main threat to apiculture and since many parasite taxa can spill over from honeybees (Apis mellifera) to other bee species, honeybee disease management is important for pollinator conservation in general. It is unknown whether honeybees that escaped from apiaries (i.e. feral colonies) benefit from natural parasite‐reducing mechanisms like swarming or suffer from high parasite pressure due to the lack of medical treatment. In the latter case, they could function as parasite reservoirs and pose a risk to the health of managed honeybees (spillback) and wild bees (spillover). We compared the occurrence of 18 microparasites among managed (N = 74) and feral (N = 64) honeybee colony samples from four regions in Germany using qPCR. We distinguished five colony types representing differences in colony age and management histories, two variables potentially modulating parasite prevalence. Besides strong regional variation in parasite communities, parasite burden was consistently lower in feral than in managed colonies. The overall number of detected parasite taxa per colony was 15% lower and Trypanosomatidae, chronic bee paralysis virus, and deformed wing viruses A and B were less prevalent and abundant in feral colonies than in managed colonies. Parasite burden was lowest in newly founded feral colonies, intermediate in overwintered feral colonies and managed nucleus colonies, and highest in overwintered managed colonies and hived swarms. Our study confirms the hypothesis that the natural mode of colony reproduction and dispersal by swarming temporally reduces parasite pressure in honeybees. We conclude that feral colonies are unlikely to contribute significantly to the spread of bee diseases. There is no conflict between the conservation of wild‐living honeybees and the management of diseases in apiculture.
