Epidemiological comments Since 30 October 2018, further surveillance has been conducted and this has resulted in further detection of varroa mite infestations in Western honey bee (Apis mellifera). A total of twenty six beehives from nine apiaries were found to be infested with Varroa mites during surveillance from 15 January 2019 to 28 January 2019. Reminder of the beehives turned negative for varroa mites during this period. Areas infested with varroa mites are being chemically treated with Fluvalinate. Zoning applied to demarcate the varroa infested area. Communication and awareness activities within the community, apiculture industry and key stakeholders are being conducted along with extensive surveillance.
