“…For this seems to have replaced N. apis in most parts of Europe (Klee et al, 2007;Gajda et al, 2013). N. apis has been linked to winter colony losses and poor spring build up (Fries, 1988), whereas N. ceranae has been reported to cause collapse of colonies in both spring and winter (Higes et al, 2009).…”

SummaryDiseases are known to be one of the major contributors to colony losses. Within a Europe-wide experiment on genotype -environment interactions, an initial 621 colonies were set up and maintained from 2009 to 2012. The colonies were monitored to investigate the occurrence and levels of key pathogens. These included the mite Varroa destructor (mites per 10 g bees), Nosema spp. (spore loads and species determination), and viruses (presence/absence of acute bee paralysis virus (ABPV) and deformed wing virus (DWV)). Data from 2010 to the spring of 2011 are analysed in relation to the parameters: genotype, environment, and origin (local vs. non-local) of the colonies in the experiment. The relative importance of different pathogens as indicators of colony death within the experiment is compared. In addition, pathogen occurrence rates across the geographic locations are described. 216Meixner et al.

“…There is currently great interest in the stress factors affecting pollinators, many of which are showing substantial population declines with knock-on effects on the plants that rely on them for pollination [17][18][19]. Parasites are well established as being an important factor in at least some of these declines, with several bumblebee species showing population declines that correlate with pathogen spillover from commercially produced bumblebees [20][21][22][23][24][25][26][27][28], and honeybee colony losses in many countries being associated with emerging parasites such as the Varroa mite and the microsporidian Nosema ceranae [29][30][31][32][33][34]. Importantly, there is increasing evidence of parasite transmission between pollinator taxa being more significant than has generally been appreciated.…”

Parasites in bloom: flowers aid dispersal and transmission of pollinator parasites within and between bee species

2015

The dispersal of parasites is critical for epidemiology, and the interspecific vectoring of parasites when species share resources may play an underappreciated role in parasite dispersal. One of the best examples of such a situation is the shared use of flowers by pollinators, but the importance of flowers and interspecific vectoring in the dispersal of pollinator parasites is poorly understood and frequently overlooked. Here, we use an experimental approach to show that during even short foraging periods of 3 h, three bumblebee parasites and two honeybee parasites were dispersed effectively onto flowers by their hosts, and then vectored readily between flowers by non-host pollinator species. The results suggest that flowers are likely to be hotspots for the transmission of pollinator parasites and that considering potential vector, as well as host, species will be of general importance for understanding the distribution and transmission of parasites in the environment and between pollinators.

“…O possível envolvimento do microsporídio N. ceranae foi reportado em colapsos de colônias nos Estados Unidos e Europa Paxton et al, 2010), no entanto, sabe-se que o patógeno está presente em todos os continentes, inclusive a América do Sul, onde colapsos ainda não estão bem documentados sistematicamente (Klee et al, 2007;Martín-Hernández et al, 2007). Embora o primeiro registro do patógeno no Brasil tenha sido feito somente em 2007 (Klee et al, 2007), recentemente foi confirmada a presença do microsporídio no país há pelo menos três décadas (Teixeira et al, 2013).…”

Resumo -Nas últimas décadas, o declínio de populações de abelhas silvestres e o colapso de colônias de Apis mellifera têm preocupado pesquisadores e apicultores. O objetivo deste artigo de revisão foi compilar alguns dos estudos mais relevantes relacionados às possíveis causas desses problemas -como nutrição, manejo, patógenos, parasitas e efeitos de agrotóxicos -, além de apresentar um breve histórico da síndrome "colony collapse disorder" (CCD) nos Estados Unidos e na Europa. Abordaram-se com mais detalhes os estudos desenvolvidos no Brasil, principalmente sobre agrotóxicos utilizados na agricultura e patógenos e parasitas que acometem as colônias de A. mellifera africanizada. Casos de enfraquecimento, declínio e colapso têm sido registrados, principalmente nos estados de São Paulo e Santa Catarina, que somam grandes perdas. Resultados das ocorrências analisadas indicaram que as mortalidades em massa registradas no Brasil não estavam associadas a patógenos ou a parasitas. Somente dois casos com características semelhantes às descritas para CCD foram registrados, porém sem causas definidas. Para que se conheçam as causas de enfraquecimentos e perdas de colônias de abelhas, é urgente a implementação de programas oficiais de levantamento sistemático da sanidade apícola, associados a pesquisas com foco nas avaliações dos possíveis impactos da fragmentação de habitats e das práticas agrícolas sobre as comunidades de abelhas.Termos para indexação: Apis mellifera, abelha africanizada, distúrbio do colapso das colônias, nutrição de abelhas, patologia apícola, polinização. Weakness and collapse of bee colonies in Brazil: are there cases of CCD?Abstract -In the last decades, the decline of wild bee populations and the collapse of Apis mellifera colonies have concerned researchers and beekeepers. The objective of this review was to compile some of the most relevant studies related to the possible causes of these problems -such as nutrition, management, pathogens, parasites, and the effects of pesticides -, besides presenting a brief history of the colony collapse disorder syndrome (CCD) in the United States and Europe. The studies developed in Brazil were presented in more detail, mainly those on pesticides used in agriculture and on pathogens and parasites that attack the colonies of Africanized A. mellifera. Cases of weakening, decline, and collapse have been recorded in Brazil, mainly in the states of São Paulo and Santa Catarina, which add up to great losses. Results of the analyzed occurrences indicated that the recorded mass mortalities were not associated with pathogens or parasites. Only two cases with characteristics similar to those described for CCD were recorded, but without defined causes. In order to know the causes of the weakening and collapses of colonies, the implementation of official programs is urgent for the systematic survey of bee health, associated with research focusing on assessments of possible impacts of habitat fragmentation and agricultural practices on bee communities.
