- q6 e2 a1 R1 M* UThe Adees lost some 25,000 colonies (nearly 40% of their operation) in California prior to almond bloom. Assuming a conservative average of 6-frame strength, and 1800 bees per frame, that is 270,000,000 bees, or nearly 40 tons of bees! The Adee bees were in large holding yards—groups of white boxes that stood out starkly in the gently rolling grass-covered hills. To think that 40 tons of bees couldn’t find or smell their ways home to the only landmarks around is rather implausible!

在杏仁开花之前,Adees在加利福尼亚州损失了大约25,000个蜂群(约占其经营的40%)。 假设保守的平均每群6个巢框和每框1800只蜜蜂,即270,000,000蜜蜂,或将近40吨蜜蜂! Adee蜜蜂在大型场地中,成群的白色盒子在平缓起伏的草丛中的山丘上显得格外醒目。 认为40吨蜜蜂找不到或闻不到周围唯一地标的回家之路,真是太不可思议了! |
