  • A large-scale survey conducted in Latin America found that on average, 30.4% of managed honey bee colonies and 39.6% of stingless bee colonies were lost each year over a two-year period (2016-2018).
  • Summer losses for stingless bees (30.9%) were higher compared to winter losses (22.2%), while honey bee losses did not show the same seasonal pattern.
  • The survey revealed significant differences in colony loss rates between countries and over the years, indicating challenges in maintaining bee colony health and economic viability for those involved in beekeeping.
