Abstract: El presente estudio se enfocó en evaluar la prevalencia y el nivel de infestación
de varroa en colmenas y núcleos en polinización comercial; y la correlación del
nivel de infestación con la población, como con el temperamento de las abejas.
Se usaron 23 colmenas y 9 núcleos del ecotipo italiana. El trabajo se realizó en
octubre (primavera) del 2021, en el distrito de Laredo, Provincia de Trujillo;
ubicado a una altura de 600 m.s.n.m. El clima del área de estudio fue árido con
poca humedad. Además, existió cultivo polifloral circundante al apiario, cuya
floración predominante fue: maíz, palto y eucalipto. Adicionalmente, los
apicultores de dicho apiario poseían 30 años de experiencia y realizaban
tratamientos contra varroa dos veces al año. Los resultados mostraron una alta
prevalencia (100%) en colmenas y núcleos evaluados, pero con bajo nivel de
infestación (<1%). Asimismo, no existió relación entre la población y el
temperamento de las colmenas (p=0.4965 y p=0.4232, respectivamente) y
núcleos (p=0.1492 y p=0.3295, respectivamente). Por lo tanto, se concluye que
el manejo sanitario realizado en el apiario es eficiente para controlar la
infestación de varroa pero no lo suficiente para evitar su propagación horizontal
en polinización comercial. Nuestros resultados sugieren que la polinización
comercial puede ser un factor de riesgo incluso para colmenas con buen control
sanitario contra varroa. Finalmente, para futuros estudios se recomienda estudiar
el efecto de diversos acaricidas antes y durante la polinización sobre nivel de
infestación.
The present study focused on evaluating the prevalence and level of varroa infestation in hives and nuclei in commercial pollination; and the correlation of the level of infestation with the population, as with the temperament of the bees. 23 hives and 9 nuclei of the Italian ecotype were used. The work was carried out in October (spring) of 2021, in the district of Laredo, Province of Trujillo; located at a height of 600 m.a.s.l. The climate of the study area was arid with low humidity. In addition, there was a polyfloral crop surrounding the apiary, whose predominant flowering was: corn, avocado and eucalyptus. Additionally, the beekeepers of said apiary had 30 years of experience and carried out varroa treatments twice a year. The results showed a high prevalence (100%) in hives and nuclei evaluated, but with a low level of infestation (<1%). Likewise, there was no relationship between the population and the temperament of the hives (p=0.4965 and p=0.4232, respectively) and nuclei (p=0.1492 and p=0.3295, respectively). Therefore, it is concluded that the sanitary management carried out in the apiary is efficient to control varroa infestation but not enough to prevent its horizontal spread in commercial pollination. Our results suggest that commercial pollination may be a risk factor even for hives with good sanitary control against varroa. Finally, for future studies it is recommended to study the effect of various acaricides before and during pollination on the level of infestation.
