A cross-sectional study was carried out from November, 2014 to April, 2015 aimed to assess the occurrence, infestation rate and associated risk factors of Varroa mite on Honeybees; investigation of the effect of propolis on varroa mites in Walmara District. Purposive sampling was used in Peasant Association; twelve apiaries and sixty four hives were randomly selected for inspection. Interviews, direct observation and experimental set up were the main data collection techniques used to gather the information. The results revealed the whole (384) bee colonies examined for Varroa mites were Positive with varies infestation range 4%-53% in brood and 4%-36% in adult Honeybees. The highest Adult infestation rate 18.20 ± 7.99% of Varroa mites was observed in Tullu Harbu, while the lowest infestation rate (14.25 ± 5.12%) was observed Wajitu Harbu. on other side The highest Brood infestation rate (22.76 ± 9.64) % of Varroa mites was observed in Nano Suba, while the lowest infestation rate 13.73 ± 5.88% was observed Wajitu Harbu. Infestation levels showed significant relationship with colony type (p=0.006). Weak colony type is highly infested than strong colony, However, associated risk factors including age, sex, educational status, duration of experience of Beekeepers, and site and hive type were not showed statistical significance with Varroa mite infestation (P>0.05). Effect of Propolis against Varroa Mite has been investigated and showed lethal effect. Propolis extracted with 70% ethanol was found to be highly toxic, at 20% (w/v) of propolis resulting in 94.44% mortality with a brief contact time of 5 sec. The study showed that whole bee colonies examined were co-existed with the mites and lethal effect of propolis on Varroa mites. Therefore, improved management system and further research to use propolis extract as a treatment option was recommended.
