“…The colonies studied showed higher varroa infestation over winter (Table 1 and 2) it can be related with the reproductive rate period of the mite which seems to be higher in winter, even in Africanized honey bees (SANTOS et al, 2015). The climate in the area studied is not temperate, however the higher varroa parasitism level during the winter is found in Africanized colonies from Brazilian regions with cold and dry winter (MORETTO et al, 1991;TURCATTO et al, 2012;PINTO et al, 2015), which may suggest that the mite is just maintaining its pattern instead of adapting to the Africanized honey bee.…”

We investigated the influence of winter and summer on Varroa destructor infestation in honey bees from the Atlantic Forest in 28 apiaries, also registering the temperature and rainfall for the locations. We found 94% of the honey bee colonies were infested by varroa mite and its prevalence was higher in summer. General varroa infestation level was 4.2±3.9%. Colonies over winter (5.12±4.8%) presented higher infestation compared to summer (3.4±2.5%) ranging from 0 to 17.8% and Pearson correlation showed a low degree of correlation between temperature (r = -0.24; p=0.03) and rainfall (r = 0.23; p=0.04) with varroa infestation levels. We concluded that seasons can influence the mite infestation level and high mite levels found in some colonies, evidencing the need for constant monitoring to avoid colony loss.

“…A gravidade da varroose pode variar de acordo com as subespécies de abelhas, condições climáticas, fluxo de néctar, período de desenvolvimento das crias e da capacidade das abelhas de detectar e remover o ácaro (Santos et al, 2015). Alguns estudos mostram que a infestação pela Varroa destroctor é duas vezes maior em ninhadas de células grandes do que em ninhadas de células pequenas.…”

RESUMO.A biodiversidade de abelhas no mundo é muito grande. São conhecidas cerca de 20.000 espécies. As abelhas são os principais polinizadores e são cruciais para muitas culturas agrícolas, além de contribuir para a conservação da biodiversidade vegetal. Muitas plantas de importância econômica dependem desses insetos polinizadores, que contribuem para aumento da produção de frutos e sementes. A criação de abelhas tem se destacado como uma das poucas atividades zootécnicas que causa baixo impacto ambiental e ao mesmo tempo proporciona um rápido retorno do capital investido. Altas taxas de mortalidade e o desaparecimento das abelhas deixam em risco a segurança alimentar nacional e internacional. Vários fatores podem contribuir para altos índices de mortalidade, dentre eles a morte da rainha, falta de reserva de alimentos, condições pobres de forrageamento em consequência da perda de habitat, exposição a pesticidas e doenças causadas por fungos, bactérias e parasitos. Entre as principais doenças que acometem as abelhas podemos destacar a Varroose, Loque Americana, Nosemosi e Desordem do Colapso das Colônias. Discutida a importância das abelhas, medidas profiláticas de controle e preservação devem ser tomadas a fim de garantir manutenção e sobrevivência das abelhas.

They are known about 20,000 species. Bees are the main pollinators and are crucial for many crops, and contribute to the conservation of plant biodiversity. Many plants of economic importance rely on these pollinating insects, which contribute to increased production of fruits and seeds. The beekeeping has emerged as one of the few animal husbandry activities that cause low environmental impact while providing a rapid return on invested capital. High mortality rates and the disappearance of bees leaving at risk the national and international food security. Several factors can contribute to high mortality rates, including the death of the queen, lack of food supply, poor conditions of foraging as a result of habitat loss, pesticide exposure and diseases caused by fungi, bacteria and parasites. Among the major diseases affect bees can highlight the Varroa mites, foulbrood American, Nosemosi and Collapse Disorder Colony. Discussed the importance of bees, prophylactic measures of control and preservation must be taken to ensure the maintenance and survival of bees.

“…Observou-se que nos três monitoramentos de ambos os municípios foram registradas taxas médias de infestação abaixo de 10% (Tabela 2), demonstrando que esses níveis estáveis de infestação (CARNEIRO et al, 2014;SANTOS et al, 2015), possivelmente pode-se atribuir ao desenvolvimento de mecanismos de resistência pela abelha africanizada (A. mellifera) (MORETTO et al, 1991), tendo em conta que essas abelhas possuem maior eficiência no comportamento de remoção de ninhadas infestadas pelo V. destructor em relação às abelhas europeias (GUERRA-JÚNIOR et al, 2000).…”

Infestação do ácaroPalavras-chave: Apicultura; Semiárido brasileiro; Varroidae; Varroose. Abstract:The goal of the present work was to analyze the rates of infestation by Varroa. destructor mite in Africanized honeybees (Apis mellifera) colonies from apiaries in Encanto and Marcelino Vieira cities, state of Rio Grande do Norte. The research was conducted during the period from September to December 2014. In average 100 to 200 adult bees (nursing honey bee workers) were collected from the brood chamber over center frames of with brood of each hive surveyed, trapped in containers containing 100 mL of 70% alcohol and sent to the laboratory of the Federal Institute of Rio Grande do Norte (IFRN) for the counting of bees and mites. The results showed an occurrence of the Varroa destructor mite in all apiaries and in all hives analyzed, obtaining an average infestation of 7.24% in Encanto city and 5.25% in Marcelino Vieira city, low infestation levels (<15%), without risk to the colonies.
