Abstract Pollination service in agricultural crops increases significantly with pollinator diversity and wild pollinator abundance. Differences in the foraging behaviour of pollinating insects are one of the reasons why pollinator diversity and abundance enhances crop pollination. Here, we focused on the foraging behaviour of honey bees and bumble bees in sweet cherry orchards. In addition, we studied the influence of bee diversity and abundance on the foraging behaviour of honey bees and bumble bees. Honey bees were found to visit fewer flowers than bumble bees. Bumble bees also showed a higher probability of changing trees between rows than honey bees. Both visitation rate and probability of row changes of honey bees increased with bumble bee diversity and with bumble bee abundance. We also found that the probability of row changes of honey bees increased with increasing bumble bee abundance. These effects of bumble bee richness and abundance on the pollination behaviour of honey bees can improve the pollination performance of honey bees in crops that depend on cross pollination. Our results highlight the higher pollination performance of bumble bees and the facilitative effect of wild pollinators to crop pollination.

大黄蜂丰度和丰富度改善了甜樱桃中的蜜蜂授粉行为

摘要 随着传粉媒介多样性和野生传粉媒介丰度的增加，农作物的授粉服务显着增加。授粉昆虫觅食行为的差异是授粉媒介多样性和丰度增强作物授粉的原因之一。在这里，我们重点研究了甜樱桃园中蜜蜂和熊蜂的觅食行为。此外，我们研究了蜜蜂多样性和丰度对蜜蜂和熊蜂觅食行为的影响。发现蜜蜂比大黄蜂访问的花朵更少。与蜜蜂相比，大黄蜂在行间更换树木的可能性也更高。蜜蜂的访问率和换行概率都随着熊蜂多样性和熊蜂丰度的增加而增加。我们还发现蜜蜂行变化的概率随着熊蜂丰度的增加而增加。熊蜂丰富度和丰度对蜜蜂授粉行为的这些影响可以提高蜜蜂在依赖异花授粉的作物中的授粉性能。我们的研究结果突出了熊蜂较高的授粉性能以及野生授粉媒介对作物授粉的促进作用。
