1. 我们比较了两个小型（约 6000 只蜜蜂）和两个大型（约 20 000 只蜜蜂）蜂群在 6 天内的觅食行为。确定各蜂群的采食地点、是否采集花蜜或花粉、采食的斑块数量、采食蜜蜂的数量以及采集花蜜的浓度。 2．尽管群体处于相同的环境中并且具有相同的遗传背景，但是来自不同群体的觅食者使用不同的觅食斑块。3． 7 月，草料丰富时，小群和大群的觅食距离相似（小群和大群的平均觅食距离分别为 0.67 公里和 0.62 公里），而在 8 月草料稀缺时，大群的觅食距离明显更远（小群和大群的平均觅食距离分别为 1.43 公里和 2.85 公里）。 4．小群体觅食的斑块数量与大群体大致相同。每分钟返回小群体的觅食者总数明显低于返回大群体的觅食者数量。这意味着，相对于它们的大小，小群体比大群体在更多的斑块上觅食。5。小蜂群和大蜂群采集的花蜜质量没有差异。然而，小群体确实比大群体收集了更多的花粉。
1. We compared the foraging behaviour of two small (approximately 6000 bees) and two large (approximately 20 000 bees) honey-bee colonies over 6 days. We determined where the bees of each colony foraged, whether they collected nectar or pollen, the number of patches foraged at, the number of bees engaged in foraging, and the concentration of the nectar collected.2. Even though the colonies were located in the same environment and had the same genetic background, foragers from different colonies used different forage patches.3. Small and large colonies foraged at a similar distance in July when forage was abundant (mean foraging distance for small and large colonies was 0.67 and 0.62 km, respectively) whereas the large colonies foraged significantly further in August when forage was scarce (mean foraging distance for small and large colonies was 1.43 and 2.85 km, respectively).4. Small colonies foraged at approximately the same number of patches as large colonies. The total number of foragers returning to the small colonies per minute was significantly lower than the number of foragers returning to the large colonies. This means that, relative to their size, small colonies foraged at more patches than large colonies.5. The quality of the nectar collected by foragers of the small and large colonies did not differ. However, small colonies did collect more pollen than large colonies.
