Summary

We investigated the population changes of Tropilaelaps clareae in Apis mellifera colonies over a 14 month period in Islamabad, Pakistan. The environmental conditions resulted in honey bee brood being present throughout the year, which allowed T. clareae to breed continuously. The phoretic period of T. clareae was very short as the infestation of the brood (8.1%) was 20 times greater than that of the adult workers (0.4%). There were rapid increases in the T. clareae population during March and April. This corresponded with the expansion of the honey bee sealed brood and an increase in the number of falling mites. The possible interactions between T. clareae and deformed wing virus are discussed.

Resumen

Investigamos los cambios en la población del ácaro Tropilaelaps clareae en colonias de Apis mellifera durante un período de 14 meses en Islamabad, Paquistán. Las condiciones ambientales permitieron la presencia de la cría de abeja a través del año, lo que favoreció la crianza de T. clareae en forma continua. El período forético de T. clareae fue muy corto, ya que la cría infestada (8,1%) fue 20 veces mayor que en las obreras adultas (el 0,4%). Hubo un rápido incremento en la población de T. clareae durante marzo y abril. Esto correspondió con el incremento en la cría de abeja operculada y con el aumento en el número de ácaros que cayeron. Se discute la posible interacción entre T. clareae y el virus de las alas deformes.
