"In our initial surveys of bee keepers working with native bees in the eighties, we estimated that they maintained more than a thousand active hives. In 1990, we only found around 400 hives, and in 2004, only 90. At this rate, we would expect the art of stingless bee keeping to disappear from the Yucatan by 2008." David Roubik, once dubbed "The Bee Man" in a National Geographic special about his work on Africanized bees, and recently featured on the PBS "Deep Jungle" series, would like people to take note:
"For thousands of years, Mayans were expert practitioners of bee husbandry, and honey was an essential forest resourceâ€¦as a sweetener, as an antibiotic and as an ingredient in the Mayan version of mead. The Mayans, like other tropical forest cultures, worked with large-bodied meliponine bees that produce a variety of honeys. Their favorite, and one of the most productive species, has been Melipona beecheii, 'Xunan kab', which means, literally, 'royal lady'."
Of the 500 or so species of stingless bees in the tropical world Melipona beecheii is unique in that it was routinely propagated. Mayan bee keepers divided existing hives in order to increase the number of hives and honey production. "That technology is all but lost, but we'd like to see it turned around, not only to ensure the survival of meliponiculture as a way of life, but also to build up breeding stock to be re-introduced into the wild where bees play an important role as pollinators," Roubik explains.
But beekeeping is fast becoming a global monoculture. Africanized honey bees produce more honey, and therefore are an economically attractive option for bee keepers. In the Mayan tradition, a priest harvested stingless bee honey as part of a religious ceremony twice a year. Over harvesting kills the colony. Native bees may simply starve as deforestation, forest fragmentation and hurricanes reduce the availability of the floral resources they need.
Finally, most of the bee keepers on the Yucatan are old men living in rural areas where no one inherits their knowledge of the fine points of meliponiculture, specifically, how to propagate bees by dividing nests. Earlier this year, Rogel Villanueva-Gutierrez, first author of the paper, with Stephen Buchmann, Arthur James Donovan and Roubik published an amply illustrated handbook, in Spanish and Mayan, with step by step instructions for basic stingless beekeeping.
The authors of this paper originally submitted their manuscript to a number of conservation journals who, in Roubik's words: "told us that there are so many extinctions, that they are not even reporting them anymore." The article, presenting a very cogent conservation strategy for saving the Mayan 'royal lady', will appear in the June, 2005, "Bee World," published by the International Bee Research Association.
