“…The large‐scale agricultural use of pesticides and the resource competition imposed by the Africanised honey bee are threats to native bees in Neotropical America, potentially more important than the decline of (Africanised) honey bees in the region, a status that largely remains unconfirmed. It is not only the Neotropics, but the whole pantropical region that houses hundreds of wild bee species that are vulnerable to agricultural pesticides .…”

Although invertebrates generally have a low public profile, the honey bee, Apis mellifera L., is a flagship species whose popularity likely derives from the products it provides and its perceived ecological services. Therefore, the raging debate regarding honey bee decline has surpassed the realm of beekeepers, academia, industry and regulatory agencies and now also encompasses non-governmental agencies, media, fiction writers and the general public. The early interest and concern about honey bee colony collapse disorder (CCD) soon shifted to the bigger issue of pollinator decline, with a focus on the potential involvement of pesticides in such a phenomenon. Pesticides were previously recognised as the potential culprits of the reported declines, particularly the neonicotinoid insecticides owing to their widespread and peculiar use in agriculture. However, the evidence for the potential pivotal role of these neonicotinoids in honey bee decline remains a matter of debate, with an increased recognition of the multifactorial nature of the problem and the lack of a direct association between the noted decline and neonicotinoid use. The focus on the decline of honey bee populations subsequently spread to other species, and bumblebees became another matter of concern, particularly in Europe and the United States. Other bee species, ones that are particularly important in other regions of the world, remain the object of little concern (unjustifiably so). Furthermore, the continuous focus on neonicotinoids is also in need of revision, as the current evidence suggests that a broad spectrum of compounds deserve attention. Here we address both shortcomings.

“…There have been efforts to encompass other species, and at least some of this research challenges the common use and extrapolation of honeybee results to other pollinators (Thompson and Hunt, 1999;Besard et al, 2011;Tomé et al, 2012;Del Sarto et al, 2014). The native Neotropical stingless bee Melipona quadrifasciata (Lepeletier) produces highly valued honey and is an important pollinator for both wild and cultivated plant species (Slaa et al, 2006;Bispo dos Santos et al, 2009).…”

Spinosad in the native stingless bee Melipona quadrifasciata: Regrettable non-target toxicity of a bioinsecticide

The risks imposed by novel insecticides, mainly bioinsecticides, are largely unknown despite their increased use and their perceived environmental safety, which is based on their natural origin. Furthermore, unlike honeybees, native pollinator species have received little attention. In the present study, the lethal and sublethal effects of the neonicotinoid imidacloprid and the bioinsecticide spinosad were assessed in the stingless bee species Meliponaquadrifasciata, an important native pollinator in the Neotropical region. The adult stingless bee workers exhibited high oral insecticide susceptibility, with LD50s of 23.54 and 12.07 ng a.i./bee for imidacloprid and spinosad, respectively. Imidacloprid also impaired worker respiration and overall group activity and flight, while spinosad significantly impaired only worker flight despite exhibiting higher oral toxicity to adult workers than imidacloprid. These findings indicate the hazardous nature not only of imidacloprid but also the bioinsecticide spinosad to adult workers of the native pollinator M. quadrifasciata. Therefore, bioinsecticides should not be exempted from risk assessment analysis due to their lethal and sublethal components.

Muitos desses ingredientes ativos, durante sua rota metabólica, afetam diferentes processos celulares que impactam a longevidade, o comportamento e a fisiologia do inseto, e podem causar efeitos individuais e consequências para a colônia ao longo do tempo.…”

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.
