Article Synopsis
- 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.
Most research on hygienic behavior has recorded the time taken by the colony to remove an experimental amount of dead brood, usually after one or two days. We evaluated the time that hygienic (H) and non-hygienic (NH) honey bees take to uncap and remove dead brood in observation hives after the brood was killed using the pin-killing assay. Four experimental colonies were selected as the extreme cases among 108 original colonies.

Hygienic lines of honey bees appear to be more sensitive to the odors of dead and diseased honey bee brood, and Africanized honey bees are generally more hygienic than are European honey bees.
