Sammanfattning: My study focuses on how the pollination frequence for wild insect pollinators was influenced by the presence of honey bees. Man made beehives, with their thousands of honey bees, can potentially affect wild insect pollinators within 3 km radius. Several studies indicate that this competition will be disadvantageous for wild insect pollinators. The study at hand was conducted in boreal areas of North Swedens southern coastal region. In each area studied, the frequency of pollinators, wild as well as domesticated, was counted in close proximity to beehives and at reference areas, distanced more than 3 kilometres from nearest hive. The reults are somewhat startling, but not statistically significant. In five of the six sites, the wild pollinators were more numerous with honey bees present.
