Varroa mites are important honey bee ecto-parasites that have caused disaster to the beekeeping industry in Europe and America. The extent of spread of these mites in Africa is not clearly known, but several sub-Saharan African countries including Uganda have been on the varroa-suspect list. We surveyed 16 districts falling in eight agroecological zones in Uganda with the aim of establishing the presence of varroa mites. Within each district, at least two subcounties were visited for honey bee sample collection and varroa detection between September 2011 and April 2013. Honey bee samples collected were screened for varroa mites by dusting with thymol. Farmers and beekeeping extension workers were interviewed on their knowledge of varroa. The results indicate that varroa mites were present in all the districts and agroecological regions sampled. Bee farmers and beekeeping extension workers were completely unaware of the presence of the varroa mites. The farmers reported no changes in honey production and honey bee foraging. We recommend empirical studies to establish the effects of varroa on local honey bee productivity and the validity of the purported resistance of the African honey bees to varroa.
