DOMINGUEZ-REBOLLEDO, Álvaro et al. Variation in the prevalence of Varroa, Nosema and Acarapis in two regions of Campeche State, Mexico. Abanico vet [online]. 2023, vol.13, e103.  Epub Oct 27, 2023. ISSN 2448-6132.  https://doi.org/10.21929/abavet2023.8.

Bees are susceptible to diseases, which cause significant economic losses in beekeeping. The objective was to evaluate the prevalence of Varroa sp, Nosema sp and Acarapis in apiaries located in two regions in Campeche, Mexico. 116 bee samples from 10 apiaries were evaluated. The prevalence of Varroa was lower in Hopelchén compared to Sihochac (98.5 and 100 %), the prevalence of Nosema was lower in Hopelchén compared to Sihochac (85.9 and 88.0 %). The Varroa infestation level was higher in Hopelchén compared to Sihochac (7.32 and 3.73 mites in 100 bees), however, the Nosema infestation level was lower in Hopelchén compared to Sihochac (78x105 and 23x106 spores per bee), and not the presence of Acarapis was found in none of the evaluated regions. In both regions a positive correlation was found between the presence of Nosema and Varroa. There is a 1.08 higher probability of finding Nosema in the presence of Varroa. We conclude that in both regions there is a high prevalence of Varroa and Nosema and the presence of Acarapis was not detected.
