Abstract

Apis mellifera pupae and their parasites Tropilaelaps and Varroa destructor were collected from honey bee hives in Palawan, Philippines for species identification of the Tropilaelaps and viral analyses. Genetic analysis identified Tropilaelaps mercedesae infesting A. mellifera on the island. Viral analyses showed that all pupae and their infesting Tropilaelaps or Varroa shared the same Deformed Wing Virus (DWV) variant infections with DWV-B being more prevalent than DWV-A. Pupae infested with either Varroa or Tropilaelaps had higher levels of both DWV variants than uninfested pupae. Vigilance is needed to prevent the spread of Tropilaelaps clareae into Palawan and T. mercedesae and DWV variants from Palawan to other provinces.
