life just before they emerge as adults, so whatever is reducing their lifespan is happening before that point," said Anthony Nearman, a Ph.D. student in the Department of Entomology and lead author of the study."This introduces the idea of a genetic component. If this hypothesis is right, it also points to a possible solution.
"When I plotted the lifespans over time, I realized, wow, there's actually this huge time effect going on," Nearman said."Standardized protocols for rearing honey bees in the lab weren't really formalized until the 2000s, so you would think that lifespans would be longer or unchanged, because we're getting better at this, right? Instead, we saw a doubling of mortality rate.
