In Canada, the Common Eastern Bumble Bee ( Cresson) is native to southern Ontario and Quebec, but since being developed as a managed commercial pollinator, it has been exported to several other provinces for use in greenhouse and field crop settings. This has enabled this species to become established outside its natural range and it is now established in eastern Canada (New Brunswick, Nova Scotia, Prince Edward Island) and British Columbia. To date, the species has not been detected via field capture in the prairie provinces.
Here we report on recent captures of workers and males from south-eastern Alberta and suggest that these specimens escaped from nearby commercial greenhouses. The risk that the presence and looming establishment of this species has on native bumble bees in the Canadian prairies is discussed.
在加拿大，东部常见大黄蜂（克雷森）原产于安大略省南部和魁北克省，但自被开发为商业化管理的传粉者以来，已被出口到其他几个省份，用于温室和大田作物环境。这使得该物种能够在其自然分布范围之外立足，现在已在加拿大东部（新不伦瑞克省、新斯科舍省、爱德华王子岛）和不列颠哥伦比亚省立足。迄今为止，在草原省份尚未通过野外捕捉发现该物种。
在此，我们报告了最近在艾伯塔省东南部捕获的工蜂和雄蜂，并认为这些标本是从附近的商业温室中逃出的。讨论了该物种的存在及其在加拿大草原地区即将立足对本地大黄蜂的风险。
