Abstract
The aim of this study was to determine the prevalence of the adult honey bee's
diseases at the Central Region of Portugal. Adult bee's samples were collected and analysed
at the Laboratory of Honey Bee Pathology at Escola Superior Agraria de Bragança
(LPAESAB). Samples were processed for epidemiological characterization of diseases of
adult honey bees. In general, the prevalence of Varroa mites and Nosemosis increased over
the years. Also, the results attained show that Varroatosis, Nosemosis and Myasis, occur
along all the years and seasons. The diagnosis of Varroatosis and Nosemosis were higher
(P<0,05) during Autumn than in the summer The Varroatosis and Nosemosis are both the
major diseases of the adult honey bees presenting the higher concerns at regional and
national level. Positive cases of Acarapisosis are indicative of a failure in acaricide treatment.
We conclude that higher efforts are needed in order to define the strategies for the control of
these diseases.info:eu-repo/semantics/publishedVersio
