Two European click beetle species, Agriotes obscurus L. (AO) and A. lineatus L. (AL) have become serious pests of agriculture in the Fraser Valley and Vancouver Island areas of British Columbia (BC), but prior to the start of this survey (2017) it was unknown if they had established elsewhere in the Province. Pitfall traps baited with sex pheromone of AO and AL were placed throughout BC in 2017–2019 and collected a total of 4,988 AO and 20,103 AL beetles in 150 trap pairs. Both species were found to be distributed throughout southern BC, including high numbers in Creston, Kelowna, Pemberton, and Salmon Arm. Traps placed in northern BC, northern Alberta, northern Idaho, or the Willamette valley in western Oregon did not collect AO or AL. Traps were also deployed for A. sputator L., a related European species that has become a serious pest of potato in eastern Canada, but this species was not collected. AO and AL traps placed in the Pemberton valley of BC also collected 474 A. ferrugineipennis (LeConte), and traps placed in the northern Okanagan valley collected 75 A. oregonensis Becker. Both are native Agriotes species not closely related to AO or AL; this is the first time A. oregonensis was collected in Canada. We discuss the potential implications of the spread of AO and AL to other agricultural areas in BC and beyond.

两种欧洲点击甲虫物种Agriotes obscurus L. (AO) 和A. lineatus L. (AL) 已成为不列颠哥伦比亚省 (BC) 菲沙河谷和温哥华岛地区的严重农业害虫，但在此之前调查（2017 年）不知道他们是否在该省的其他地方建立。2017-2019 年在整个 BC 省放置了以 AO 和 AL 性信息素为诱饵的陷阱，在 150 个陷阱对中总共收集了 4,988 只 AO 和 20,103 只 AL 甲虫。发现这两种物种都分布在不列颠哥伦比亚省南部，包括大量分布在克雷斯顿、基洛纳、彭伯顿和鲑鱼湾。位于 BC 北部、阿尔伯塔北部、爱达荷州北部或俄勒冈州西部威拉米特河谷的陷阱没有收集 AO 或 AL。还部署了陷阱A. sputator L.，一种相关的欧洲物种，已成为加拿大东部马铃薯的严重害虫，但该物种未被采集。放置在不列颠哥伦比亚省彭伯顿山谷的 AO 和 AL 陷阱也收集了 474 只A. ferrugineipennis (LeConte)，放置在 Okanagan 山谷北部的陷阱收集了 75 A. oregonensis Becker。两者都是与 AO 或 AL 没有密切关系的本地Agriotes物种；这是第一次在加拿大收集俄勒冈曲霉。我们讨论了 AO 和 AL 传播到不列颠哥伦比亚省及其他地区的其他农业地区的潜在影响。
