DOWNLOAD EBOOK →Apiary inspectors and beekeepers must be able to recognize bee diseases and parasites and to differentiate the serious diseases from the less important ones. This handbook describes laboratory techniques used to diagnose diseases and other abnormalities of the honey bee and to identify parasites and pests. Emphasis is placed on the techniques used by the U.S. Department of Agriculture Bee Research Laboratory. Included are directions for submitting, through APHIS-PPQ or state regulators, samples of suspected Africanized honey bees for identification of subspecies. Also included are directions for sending diseased brood and adult honey bees for diagnosis of bee disease.

Questionnaire survey and laboratory diagnostic methods were used for the study. The questionnaire was administered to 146 beekeepers (97,1% males)and two honeybee colony samples from each beekeeper totally (292 honeybee colonies) were collected from transitional and frame box hives for laboratory diagnosis. The honeybee samples collected were examined in laboratory for the prevalent and incidence rate of honeybee disease pathogens and pests. Majority of the respondents started beekeeping after 2010 (28.03%) by catching colonies as honey bee colony source (54.8%). The major dearth period of the area was late march to early may. The trend of beekeeping in the study area was shifting from traditional to modern beekeeping and the trend of honeybee colony and its yield was decreasing due to honeybee health problem of the area (pests, predators, pathogenic disease, high cost of bee equipment and agro-chemical application). In the study area the major pests and predators considered as challenges were ants, beetles, wax moth, varroa destructor and some predators like honey badgers, bee eater birds, dead head hawks moth, lizards, wasps and birds respectively. Varroa, Nosema, Amoeba and chalk brood disease were confirmed while tracheal mite, stone brood, Ameriacan and Europian foul brood did not confirmed during the study period. The prevalentand incidence of varroa destructor was higher in dry season than wet season while the prevalent/incidence rate of nosema and chalk brood disease was limited during dry season. Amoeba disease was distributed in both seasons.For the reason of time restraint in this study area, farther study on economic threshold of honeybee disease and pests is suggested by monitoring throughout the year.
