Beekeeping in the United States dates back to the 1860s. ==Development of beekeeping in the United States== John Harbison, originally from Pennsylvania, successfully brought bee keeping to the US west coast in the 1860s, in an area now known as Harbison Canyon, California, and greatly expanded the market for honey throughout the country. Beekeeping was traditionally practiced for the bees' honey harvest, although nowadays crop pollination service can often provide a greater part of a commercial beekeeper's income. Other hive products are pollen, royal jelly, and propolis, which are also used for nutritional and medicinal purposes, and beeswax, which is used in candle making, cosmetics, wood polish, and for modelling. The modern use of hive products has changed little since ancient times. Western honey bees are not native to the Americas. American colonists imported honey bees from Europe for their honey and wax. Their value as pollinators began to be appreciated by the end of the nineteenth century. The first honey bee subspecies imported were likely European dark bees. Later Italian bees, Carniolan honey bees and Caucasian bees were added. Western honey bees were also brought from the Primorsky Krai in Russia by Ukrainian settlers around the 1850s. These Russian honey bees that are similar to the Carniolan bee were imported into the U.S. in 1990. The Russian honey bee has shown to be more resistant to the bee parasites ''Varroa destructor'' and ''Acarapis woodi'', although their commercial use and availability are extremely limited in scope because other, better strains are available (e.g., VSH lines). Before the 1980s, most U.S. hobby beekeepers were farmers or relatives of a farmer, lived in rural areas, and kept bees with techniques passed down for generations. The arrivals of tracheal mites and varroa mites in the 1980s and small hive beetles in the 1990s have made the practice more challenging for the hobbyist. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Beekeeping in the United States」の詳細全文を読む スポンサード リンク
