1.虽然花粉是蜜蜂重要的营养来源，但花粉质量对蜜蜂觅食行为的影响却知之甚少。在选择试验中，蜜蜂没有表现出天生的花粉觅食偏好，但在经历了油菜的觅食经验后，蜜蜂更喜欢油菜花粉而不是蚕豆花粉.采用高效液相色谱法对油菜花粉和菜豆花粉中游离氨基酸含量进行了比较。油菜花粉比蚕豆花粉含有更大比例的蜜蜂所需的最必需的氨基酸（缬氨酸、亮氨酸和异亮氨酸），这表明油菜花粉比蚕豆花粉对蜜蜂具有更高的营养品质.蜜蜂觅食的偏好似乎反映了花粉质量。花粉氨基酸组成影响蜜蜂觅食行为的假说进行了讨论。
1. Although pollen is a vital nutritional resource for honey bees, Apis mellifera, the influence of pollen quality on their foraging behaviour is little understood.2. In choice-test experiments, bees showed no innate pollen-foraging preferences, but preferred oilseed rape Brassica napus pollen over field bean Vicia faba pollen after previous foraging experience of oilseed rape.3. The free amino acid content of oilseed rape and field bean pollen was compared using high-performance liquid chromatography. Oilseed rape pollen contained a greater proportion of the most essential amino acids required by honey bees ( valine, leucine, and isoleucine) than field bean, suggesting that oilseed rape pollen is of greater nutritional quality for honey bees than is field bean pollen.4. Honey bee foraging preferences appeared to reflect pollen quality. The hypothesis that pollen amino acid composition affects the foraging behaviour of honey bees is discussed.
