We report the strawberry blossom weevil, Anthonomus rubi (Herbst, 1795) (Coleoptera: Curculionidae), a species native to Europe, Asia, and North Africa, as established in British Columbia, Canada. This is the first report of A. rubi in North America. We provide a diagnosis of the species and compare it with other species of the genus Anthonomus Germar in Canada. This species is a pest of plants in Rosaceae Jussieu, including economically important berries such as strawberries (Fragaria Linnaeus) and raspberries (Rubus idaeus Linnaeus), and of native berries of importance to Indigenous peoples in Canada. Female weevils oviposit eggs inside developing flower buds and sever flower stalks, facilitating larval development inside damaged buds and thus reducing fruit yields. Surveys to confirm the presence of A. rubi conducted in 2020 found the weevil to be well established in cultivated and wild hosts throughout the Greater Vancouver area and Fraser Valley, British Columbia. At least one species of parasitoid wasp in the genus Pteromalus Swederus (Hymenoptera: Pteromalidae) has been found in association with A. rubi in the province. Future investigations are required to understand the biology of A. rubi in its new range, assess its impact on berries, and develop management strategies.

我们报告了草莓开花象鼻虫Anthonomus rubi (Herbst, 1795) (Coleoptera: Curculionidae)，一种原产于欧洲、亚洲和北非的物种，在加拿大不列颠哥伦比亚省建立。这是北美首次报道A. rubi。我们提供该物种的诊断，并将其与加拿大Anthonomus Germar属的其他物种进行比较。本种是蔷薇科Jussieu植物的害虫，包括经济上重要的浆果，如草莓（Fragaria Linnaeus）和覆盆子（Rubus idaeus）Linnaeus），以及对加拿大土著人民很重要的本地浆果。雌性象鼻虫在发育中的花蕾内产卵并切断花茎，促进受损花蕾内的幼虫发育，从而降低果实产量。2020 年进行的确认A. rubi存在的调查发现，该象鼻虫在整个大温哥华地区和不列颠哥伦比亚省弗雷泽河谷的栽培和野生宿主中均已成熟。在该省发现了至少一种寄生蜂属Pteromalus Swederus（膜翅目：Pteromalidae）与A. rubi相关。需要进一步的研究来了解A. rubi的生物学 在其新系列中，评估其对浆果的影响，并制定管理策略。
