Differentiating Nosema apis (Type A: fecal spots, crawling bees, winter weakness) from N. ceranae (Type C: subtle population decline, no dysentery, year-round vigor loss) is crucial. Lab diagnosis focuses on % infected bees (>50% predicts collapse). Early detection ensures overwinter survival and productivity through targeted management.
