First North American records are presented for Frölich, 1799 (Coleoptera, Chrysomelidae, Bruchinae), as confirmed by morphology from multiple sites in Canada: British Columbia, Ontario, and Québec. Diagnostic information is presented for in North America. This insect is expected to reduce plant reproductive output in infested L., L., and other potential (Fabaceae) hosts. Impacts on broad bean ( L.) production are expected to be small. Potential reproductive impact on native North American species remains unknown. The United States of America and Canada are now known to be home to 69-79 species of adventive Chrysomelidae including 16-18 Bruchinae. We have found two dead, teneral individuals inside seeds imported from Europe, and we hypothesise that this species was introduced to Canada from Europe via seeds for planting sometime before 2007. At our study sites, flowering began in mid June followed by oviposition in late June with first adults emerging in late August, requiring about 60 days from egg to adult stage. (Rodani, 1877) (Hymenoptera, Pteromalidae) was newly recorded as parasitoid of in Canada, and caused about 10% mortality in at our sites.
首次在北美记录到弗罗利希象甲（Frölich, 1799）（鞘翅目，叶甲科，豆象亚科），该记录经加拿大多个地点（不列颠哥伦比亚省、安大略省和魁北克省）的形态学确认。文中给出了该象甲在北美的鉴别信息。预计这种昆虫会降低受侵染的蚕豆（Vicia faba L.）、野豌豆（Vicia sativa L.）及其他潜在豆科（豆科）寄主植物的繁殖产量。预计对蚕豆（Vicia faba L.）产量的影响较小。对北美本土豆科物种的潜在繁殖影响仍未知。现在已知美国和加拿大有69 - 79种外来叶甲科昆虫，其中包括16 - 18种豆象亚科昆虫。我们在从欧洲进口的种子内发现了两只死亡的、刚羽化的个体，我们推测该物种在2007年之前的某个时间通过用于种植的种子从欧洲引入到了加拿大。在我们的研究地点，蚕豆在6月中旬开始开花，随后在6月下旬产卵，8月下旬出现首批成虫，从卵到成虫阶段大约需要60天。啮小蜂（Tetrastichus pici (Rodani, 1877)）（膜翅目，啮小蜂科）在加拿大被新记录为弗罗利希象甲的寄生蜂，在我们的研究地点导致该象甲约10%的死亡率。
