Biocultural Diversity Loss: the Decline of Native Stingless Bees (Apidae: Meliponini) and Local Ecological Knowledge in Michoacan, Western Mexico

Local ecological knowledge (LEK) is of utmost importance for biodiversity conservation; however, a number of studies document the loss of LEK regarding native bees. Stingless bees (Apidae: Meliponini) are important pollinators that have been managed by humans in all tropical areas of the world. Our work documents the decline of Meliponini and associated LEK in the state of Michoacan, western Mexico, as well as local historical management and perceptions of the diversity and abundance of bees. Through ecological sampling, semi-structured interviews, and participant observation, we established the presence of 13 species of Meliponini and recognition of 23 local names. Although stingless bees' pot-honey is harvested directly through extraction of wild nests, local knowledge about bee diversity, behavior, and use can contribute to their conservation. Because of recent access to manufactured products and the scarcity of wild nests, LEK and pot-honey harvest are being abandoned and forgotten in some areas. Maintaining LEK is important in designing sustainable use strategies to prevent the extinction of wild nests and allow conservation of bees as well as the cultural legacy associated with them, essential in the context of a global decline of pollinators.
