Abstract The distribution of Trogoderma granarium Everts has expanded steadily in recent years. This is a very destructive coleopteran species with many economic implications for the trade of grains in countries where it is present. Therefore, it is important to gather data that can confirm or reject the pest’s establishment in a particular country. Spain has been cited as a location where the species is established; however, the present study demonstrates that no actual data support its stablishment in Spain. We surveyed fifteen storage premises (mills and warehouses for animal feed, wheat, and rice) distributed along the Iberian Peninsula over two years. We used traps baited with Trogoderma spp. sex pheromone to conduct the survey. Collected samples were morphologically and molecularly identified, since the morphological identification of this species is difficult. Although we found populations of T. inclusum in most of the sampled premises, and even T. variabile in one of them, no T. granarium was found in any of them. Abundant samples of other coleopterans were captured in the traps, including Oryzaephilus surinamensis, Tribolium spp., Sitophilus spp., Cryptolestes ferrugineus, Lasioderma serricorne and Rhyzopertha dominica. In conclusion, no T. granarium was found in our samplings in Spain.

Trogoderma spp. 的调查。在西班牙工厂和仓库

摘要 近年来，Trogoderma granarium Everts 的分布稳步扩大。这是一种非常具有破坏性的鞘翅目物种，对存在它的国家的谷物贸易具有许多经济影响。因此，重要的是收集可以确认或拒绝特定国家有害生物定殖的数据。西班牙被认为是该物种的栖息地。然而，目前的研究表明，没有实际数据支持其在西班牙的成立。两年来，我们调查了分布在伊比利亚半岛的 15 个仓库（动物饲料、小麦和大米的工厂和仓库）。我们使用了以 Trogoderma spp 为诱饵的陷阱。性信息素进行调查。收集的样本进行形态学和分子学鉴定，因为这个物种的形态学鉴定是困难的。尽管我们在大多数抽样场所中发现了 T. inclusum 种群，甚至在其中一个中发现了 T. variabile，但在其中任何一个中都没有发现 T. granarium。陷阱中捕获了大量其他鞘翅目昆虫，包括 Oryzaephilus surinamensis、Tribolium spp.、Sitophilus spp.、Cryptolestes ferrugineus、Lasioderma serricorne 和 Rhyzopertha dominica。总之，我们在西班牙的采样中没有发现 T. granarium。Lasioderma serricorne 和 Rhyzopertha dominica。总之，我们在西班牙的采样中没有发现 T. granarium。Lasioderma serricorne 和 Rhyzopertha dominica。总之，我们在西班牙的采样中没有发现 T. granarium。
