Abstract

A high infestation rate of honeybee (Apis mellifera) colonies by Tropilaelaps clareae mites was found in Afghanistan and southern Vietnam and a low rate in northern Vietnam. The rate of infestation by Varroa jacobsoni was low in both parts of Vietnam. The ratios of brood: worker infestation by T. clareae ranged from 13.5-16.0 in Afghanistan and southern Vietnam and 26.1-36.9 in northern Vietnam. The corresponding ratios for V. jacobsoni were 0.8 in southern Vietnam and 2.9-8.2 in the north. These data suggest that in the colder areas V. jacobsoni mites remain outside sealed brood for a shorter time, resulting in a more rapid population increase there.
