Epidemiological comments Asian honey bee (Apis cerana) hive detected in the Port of Townsville, destroyed on 27 June 2016. Dead bees and comb submitted for testing on the same day to the Department of Agriculture and Water Resources, Operational Science Program, in Brisbane. Varroa species was detected. Varroa jacobsoni was confirmed morphologically by CSIRO (Commonwealth Scientific and Industrial Research Organisation), Black Mountain, Canberra, Australian Capital Territory, on 30 June 2016. Molecular analysis is currently being undertaken. Genetic studies of the hive will be carried out to determine the possible origin of the bees. Further surveillance work, since 27 June, has not resulted in further detections of Asian honey bee (Apis cerana). Along with surveillance, communication and awareness activities within the community and industry are being undertaken.
