Insularity and its impact on stingless bee honey properties: A case study in the Zanzibar Archipelago (Tanzania)

Abstract

BackgroundIslands are known to host unique flowering plant assemblages visited by insular insects, including by social bees, a phenomenon thought to potentially impact honey composition and associated medicinal applications. In this study, we characterized several physical–chemical parameters of honeys produced by the stingless bee Meliponula (Axestotrigona) ferruginea with samples collected both from continental (Kenya) and insular (Tanzania) ecosystems.ResultsOur results show that stingless bees in islands produce a honey whose composition significantly differ from those produced in the continent, with a significantly higher concentration of bioactive phytochemicals.ConclusionOur results illustrate how insularity might drive different and unique compositional profiles in honeys and provide evidence that certain groups of compounds found in stingless bee honey from the Afrotropical region have potential therapeutic benefits with medicinal applications that largely remain to be explored.This article is protected by copyright.
