蜜蜂是许多农作物的重要授粉者。与大黄蜂相比，蜜蜂对番茄花的吸引力较小。花香通常在调节蜜蜂的觅食行为中起重要作用，番茄花释放特殊的气味。然而，很少有人知道番茄花香如何调节这两个蜜蜂类群的觅食行为。在目前的研究中，我们调查了广泛使用的传粉蜜蜂蜜蜂意大利蜜蜂和本地熊蜂，熊蜂，番茄花的觅食行为，以评估这两种蜜蜂在日光温室番茄授粉的潜在应用。此外，我们确定了蜜蜂和熊蜂是否对番茄花香表现出不同的反应，以及先天偏见和先前经验如何影响蜜蜂的选择行为。我们发现，天真的蜜蜂没有表现出对番茄花香的偏好，但在学习将番茄花香与觅食经验或气味学习程序的基础上的食物奖励联系起来后，可以发展出这种偏好。因此，蜜蜂的气味学习经验与食物奖励可以改变蜜蜂的先天偏见，并可用于提高蜜蜂为经济作物授粉服务的效率。蜜蜂对花香的反应通常受到先天偏见和先前经验的影响。番茄花对蜜蜂的吸引力不如大黄蜂。然而，关于番茄花香如何调节蜜蜂和熊蜂的觅食行为却知之甚少。本研究以温室番茄花为材料，研究了意大利蜜蜂（Apis mellifera）和熊蜂（Bombus lantschouensis）的觅食行为。研究了两种蜜蜂对番茄花香的反应是否不同，以及先天偏见和先前经验如何影响蜜蜂的选择行为。在温室里，蜜蜂无法从番茄花上采集花粉，它们的觅食活动在几天内显著减少。此外，无论是天真的蜜蜂还是天真的熊蜂都没有表现出对Y型嗅觉仪中的番茄花香的偏好。然而，在番茄温室觅食的经验，帮助熊蜂制定了强烈的偏好的气味，而觅食经验的蜜蜂继续表现出厌恶番茄花香。在学会将番茄花香与糖奖励在长鼻延伸反应（PER）测定后，这两种蜜蜂在Y型管嗅觉仪中表现出对番茄花香的偏好。研究结果表明，先前的经验与食物奖励强烈影响蜜蜂偏好番茄花香。
Bees are important pollinators for many agricultural crops. Compared with bumblebees, honeybees are less attracted to tomato flowers. Floral scent usually plays an important role in mediating the foraging behavior of bees, and tomato flowers release special scents. However, little is known about how tomato floral scent regulates the foraging behaviors of these two bee taxa. In the current study, we investigated the foraging behaviors of the widely used pollinator honeybee Apis mellifera and a native bumblebee, Bombus lantschouensis, on tomato flowers to evaluate the potential application of these two bee species for tomato pollination in solar greenhouses. Moreover, we determined whether honeybees and bumblebees show different responses to tomato floral scent and how innate biases and prior experience influence bee choice behavior. We found that naïve bees showed no preference for tomato floral scent but could develop such a preference after learning to associate tomato floral scent with a food reward on the basis of foraging experience or scent-learning procedures. We conclude that scent-learning experiences with food reward can change the innate bias of bees and could be utilized to improve the pollination service efficiency of bees for commercial crops. Bee responses to floral scent are usually influenced by both innate biases and prior experience. Honeybees are less attracted than bumblebees to tomato flowers. However, little is known about how tomato floral scent regulates the foraging behaviors of honeybees and bumblebees. In this study, the foraging behaviors of the honeybee Apis mellifera and the bumblebee Bombus lantschouensis on tomato flowers in greenhouses were investigated. Whether the two bee species exhibit different responses to tomato floral scent and how innate biases and prior experience influence bee choice behavior were examined. In the greenhouses, honeybees failed to collect pollen from tomato flowers, and their foraging activities decreased significantly over days. Additionally, neither naïve honeybees nor naïve bumblebees showed a preference for tomato floral scent in a Y-tube olfactometer. However, foraging experience in the tomato greenhouses helped bumblebees develop a strong preference for the scent, whereas honeybees with foraging experience continued to show aversion to tomato floral scent. After learning to associate tomato floral scent with a sugar reward in proboscis extension response (PER) assays, both bee species exhibited a preference for tomato floral scent in Y-tube olfactometers. The findings indicated that prior experience with a food reward strongly influenced bee preference for tomato floral scent.
