The present study was conducted to quantify at the individual level the grooming behavior of bees from resistant colonies and susceptible colonies. Experienced and naive bees from resistant colonies were compared to experienced and naive bees from susceptible colonies at the age of 4, 7, 15 and 21 days. In a total of 480 assays, resistant bees successfully groomed off 10 times more mites placed than susceptible bees. Worker of different ages are involved but the lowest percentage of grooming was observed in 21-day-old bees. The experienced bees from resistant colonies bees that have evolved in a natural environment removed significantly more mites (69.2%) compared to naive bees (51.7%) who had no contact with other older bees.

13年自然选择后易感和抗性蜜蜂群体的梳理行为差异

本研究旨在在个体水平上量化来自抗性蜂群和易感蜂群的蜜蜂的梳理行为。在 4、7、15 和 21 天时将来自抗性菌落的有经验的和幼稚的蜜蜂与来自易感菌落的有经验的和幼稚的蜜蜂进行比较。在总共 480 次检测中，抗性蜜蜂成功地清除了比易感蜜蜂多 10 倍的螨虫。涉及不同年龄的工人，但在 21 天大的蜜蜂中观察到的梳理百分比最低。与没有与其他老蜜蜂接触的幼稚蜜蜂 (51.7%) 相比，在自然环境中进化的抗性蜂群中的经验丰富的蜜蜂清除了更多的螨虫 (69.2%)。
