Small hive beetle 'SHB', Aethina tumida (Murray) is a pest and scavenger of honeybees and bee products. The study was conducted to investigate the effects of small hive beetle on honeybees and evaluating the effectiveness of different control methods at Bakko apiary site, western Ethiopia. A total of 32 honeybee colonies (Apis mellifera) were established and assigned into four treatment groups: seasonal colony management, hive entrance modification, trapping of small hive beetle larvae and control groups. Data on bee population, brood areas measure, infested comb and pollen and nectar store areas were recorded using Liebefeld method (frame unit area, 10 x10 cm2 ) at every 21 days. Also, records on small hive beetle infestation rate, average honey yield and absconded tendency of bee colonies were taken. The result indicates that there is statistically significant difference (P< 0.05) between treated and untreated colonies with high infestation rate and absconding tendency of the untreated colonies reaching about 80% and 7.33+2.6, respectively. Highest mean honey yield (23.5kg/hive) was recorded in seasonal colony management and the lowest (6.3kg/hive) was recorded in untreated groups. Significantly greatest bee population, brood area measure, pollen and nectar stores were also registered in seasonal colony management groups followed by hive entrance modification. Hence, providing bee colonies with proper seasonal management strategies is revealed to be the best option for the minimization and control of small hive beetles effect on honeybees and their products.
