Rapeseed (Brassica napus L.) is the second most produced oilseed crop in the world. It provides a high-quality nutrient for pollinating insects, and pollination, in many cases, increases crop yield. Although a large number of species visit rapeseed crops, Apis mellifera (Hymenoptera: Apidae) is the most frequent, abundant, and with the highest pollination potential. Our aim was to evaluate the effect of A.mellifera on the different yield components of Brassica napusL. (cv. Rivette). The hypothesis of the study was that the presence of pollinators would increase rapeseed crop yield and improves maturation uniformity. Four trials were conducted (one in 2013, two in 2015, and one in 2016) in commercial rapeseed crops, using pollinator exclusion tents placed during the flowering period. A randomized complete block design with two treatments and six replications during 2013 and three replications during 2015 and 2016 was used. Treatments consisted of exclusion tents with the addition of an active beehive (WITH) and without a beehive (EXCLUDED). WITH treatments showed greater uniformity on siliques maturation and a lower proportion of flowers at maturity. Rapeseed yield was determined by the site (season and farm) (P < 0.0005) and treatments (WITH or EXCLUDED) (P = 0.0482), with no interaction between them (P = 0.1217). Grain yield in WITH treatments was 14% higher than in EXCLUDED treatments (2089 vs. 1836 kg ha⁻¹). In 12 out of 15 (80%) experimental units, WITH treatment yields were higher than EXCLUDED treatments. Results show that A.mellifera can increase rapeseed yields, despite a high rate of self-fertilization.

油菜籽 ( Brassica napus L.) 是世界上产量第二大的油料作物。它为授粉昆虫提供优质养分，在许多情况下，授粉可以提高作物产量。尽管有大量物种访问油菜籽作物，但Apis mellifera（膜翅目：蜜蜂科）是最频繁、最丰富且授粉潜力最高的物种。我们的目的是评估意大利蜜蜂对欧洲油菜不同产量构成的影响L.（简历 Rivette）。该研究的假设是传粉者的存在会增加油菜籽作物的产量并提高成熟的均匀性。在商业油菜籽作物中进行了四项试验（一项在 2013 年，两项在 2015 年，一项在 2016 年），使用的是在开花期放置的传粉者排除帐篷。使用了随机完整区组设计，在 2013 年进行了两次处理和六次重复，在 2015 年和 2016 年进行了三次重复。处理包括排除帐篷加上一个活跃的蜂箱 (WITH) 和没有蜂箱 (排除)。WITH 处理显示长角果成熟的一致性更高，成熟时花的比例更低。油菜籽产量由地点（季节和农场）（P < 0.0005）和处理（有或排除）（P = 0.0482）决定，它们之间没有交互作用 (P = 0.1217)。WITH 处理的谷物产量比 EXCLUDED 处理高 14%（2089对比_ 1836 千克公顷^-1 )。在 15 个实验单元中的 12 个（80%）中，WITH 处理的产量高于 EXCLUDED 处理。结果表明，尽管自花授粉率很高，但意大利蜜蜂可以提高油菜籽的产量。
