Ethiopia: It is known, that propolis can be harvested from every hive type and 95% of Ethiopian beekeepers use traditional hives. [1] [2] [3] While the yield of propolis is higher in traditional hives, the quality is lower due to a mixture of pure propolis with beeswax, hive debris or dead bees. [2] So far, there is no information on propolis in tropical Africa (e.g. best harvesting time, how much propolis can be expected per colony, impact of propolis production on other bee products, factors that affect the propolis production, official numbers, ...). Nuru et al. (2002) conducted a study, where propolis production was induced in traditional and in modern hive-systems. They exposed the hives to the external environmental conditions, by creating gaps within the hive. Bees show the behavior of filling those openings and, as prior expected, the propolis yield was higher in manipulated hive-systems. They found not only a correlation between the data of local weather stations and the propolis production, but also a significant difference between the amount of harvested propolis of traditional and modern bee hives. The authors claim, that small, cost effective methods can help to increase the outcome significantly. [2]
Indonesia: Stingless bees of the genus Trigona are known to produce more propolis than Apis species, therefore, Indonesian beekeepers use mainly colonies of Trigona spp. for the propolis production ("meliponiculture"). [4] Unfortunately, there is no information on propolis business in Indonesia (e.g. best harvesting time, how much propolis can be expected per colony, impact of propolis production on other bee products, factors that affect the propolis production, official numbers, ...)!
