First large-scale study reveals important losses of honey bee and stingless bee colonies in Latin America

“Winter is a major challenge for bee colonies in temperate regions, as colonies must survive months with low temperatures, confinement in the hive and lack of pollen and nectar intake. Thus, winter colony losses are expected to be higher than summer losses. However, in several Latin American countries (e.g. Argentina, Bolivia, Colombia), similar or even higher loss rates were found in the summer compared to the winter in honey bees. Similar results were observed in the United States, with summer losses reaching or even exceeding winter losses . Moreover, in South Africa where only summer losses were estimated, honey bee colony loss reached up to 46%. We also observed higher loss rates in summer compared to winter in stingless bees for several L. Am. countries (Argentina, Bolivia, Brazil and Colombia).”
