“…Studies on regional scales report that pathogens also affect the abundance of bumble bees. Common reported pathogens of Bombus are trypanosomes and microsporidia, which are transmitted horizontally between bumble bee colonies and vertically within colonies [ 15 , 16 ]. In particular, the bumblebee Bombus terrestris and its parasite Crithidia bombi were studied extensively to determine the role of brood in disease transmission [ 17 ].…”

Solitary bees are subject to a variety of pressures that cause severe population declines. Currently, habitat loss, temperature shifts, agrochemical exposure, and new parasites are identified as major threats. However, knowledge about detrimental bacteria is scarce, although they may disturb natural microbiomes, disturb nest environments, or harm the larvae directly. To address this gap, we investigated 12 Osmia bicornis nests with deceased larvae and 31 nests with healthy larvae from the same localities in a 16S ribosomal RNA (rRNA) gene metabarcoding study. We sampled larvae, pollen provisions, and nest material and then contrasted bacterial community composition and diversity in healthy and deceased nests. Microbiomes of pollen provisions and larvae showed similarities for healthy larvae, whilst this was not the case for deceased individuals. We identified three bacterial taxa assigned to Paenibacillus sp. (closely related to P. pabuli/amylolyticus/xylanexedens), Sporosarcina sp., and Bacillus sp. as indicative for bacterial communities of deceased larvae, as well as Lactobacillus for corresponding pollen provisions. Furthermore, we performed a provisioning experiment, where we fed larvae with untreated and sterilized pollens, as well as sterilized pollens inoculated with a Bacillus sp. isolate from a deceased larva. Untreated larval microbiomes were consistent with that of the pollen provided. Sterilized pollen alone did not lead to acute mortality, while no microbiome was recoverable from the larvae. In the inoculation treatment, we observed that larval microbiomes were dominated by the seeded bacterium, which resulted in enhanced mortality. These results support that larval microbiomes are strongly determined by the pollen provisions. Further, they underline the need for further investigation of the impact of detrimental bacterial acquired via pollens and potential buffering by a diverse pollen provision microbiome in solitary bees.

“…Un estudio reciente muestra una alta prevalencia del microsporidio Nosema ceranae en B. pauloensis y B. bellicosus (72% y 63%, respectivamente) (Arbulo et al, 2015). Este microsporidio se ha encontrado en varias especies de abejorros (Plischuk et al, 2009(Plischuk et al, , 2017Li et al, 2012;Graystock et al, 2013;Fürst et al, 2014) y en el caso de B. terrestris, aparece como muy virulento afectando la supervivencia de los insectos (Graystock et al, 2013). También se identificaron en especímenes de Uruguay de B. pauloensis varios virus que aparecen frecuentemente en las abejas melíferas como el BQCV (Black queens cell virus), DWV (Deformed wing virus), ABPV (Acute bee paralysis virus) y el SBV (Sacbrood virus) (Salvarrey, datos no publicados).…”

“…Previous studies reported the presence of internal and external parasites in queens, workers and males of both species, including the microsporidia N . ceranae [ 16 , 41 ] and Tubulinosema pampeana Plischuk et al, the nematode Sphaerularia bombi Dufour, one species of parasitoid diptera [ 41 ], and the external mites, Kuzinia spp. Zachvatkin, Pneumolaelaps longanalis Hunter and Husband, Pneumolaelaps longipilus Hunter, Scutacarus acarorum Goeze, and Tyrophagus putrescentiae Schrank [ 42 ].…”

Bumble bees (Bombus spp.) are important pollinators insects involved in the maintenance of natural ecosystems and food production. Bombus pauloensis is a widely distributed species in South America, that recently began to be managed and commercialized in this region. The movement of colonies within or between countries may favor the dissemination of parasites and pathogens, putting into risk while populations of B. pauloensis and other native species. In this study, wild B. pauloensis queens and workers, and laboratory reared workers were screened for the presence of phoretic mites, internal parasites (microsporidia, protists, nematodes and parasitoids) and RNA viruses (Black queen cell virus (BQCV), Deformed wing virus (DWV), Acute paralysis virus (ABCV) and Sacbrood virus (SBV)). Bumble bee queens showed the highest number of mite species, and it was the only group where Conopidae and S. bombi were detected. In the case of microsporidia, a higher prevalence of N. ceranae was detected in field workers. Finally, the bumble bees presented the four RNA viruses studied for A. mellifera, in proportions similar to those previously reported in this species. Those results highlight the risks of spillover among the different species of pollinators.
