1. Ips acuminatus (the sharp‐toothed bark beetle, STBB) is currently considered to be one of the most serious pests of Scots pine in many European countries. STBB management is among the most challenging tasks in pine forests; the development of methods for monitoring, predicting and managing outbreaks of this bark beetle is therefore crucial.
2. Pheromone‐baited traps have been widely recommended as a valuable tool for the monitoring and mass trapping of bark beetles. Although different suppliers offer a variety of STBB lures, their effectiveness has rarely, if ever, been evaluated under natural conditions.
3. We evaluated the attractiveness of three commercially available and five experimental synthetic lures by comparing the numbers of STBBs captured in white, six‐funnel traps. The studies were conducted in 2017–2019 in Poland, in Scots pine‐dominated forests affected by STBB outbreaks.
4. Our study demonstrated significant differences in the effectiveness of the lures. The experimental lure produced by the Witasek company (Austria) and the recently marketed lure Acumodor Micro from Chemipan (Poland) were the most attractive to STBB. Among the least effective were two commercial lures (Acuwit and Acumodor), hitherto used in Central Europe.
5. The results will be useful in developing methods for the monitoring and management of STBB populations.

不同引诱剂对引诱Ips acuminatus的效力（鞘翅目：Curculionidae：Scolytinae）

1. Ips acuminatus（尖齿树皮甲虫，STBB）目前被认为是许多欧洲国家最严重的苏格兰松树害虫之一。STBB管理是松树林中最具挑战性的任务之一；因此，开发监测，预测和管理这种树皮甲虫暴发的方法至关重要。
2. 广泛建议使用信息素诱饵诱捕器作为监视和大规模诱捕树皮甲虫的有价值的工具。尽管不同的供应商提供了多种STBB诱饵，但是，即使在自然条件下也很少评估其有效性。
3. 通过比较在白色六漏斗捕集器中捕获的STBB的数量，我们评估了三种市售诱饵和五种实验性合成诱剂的吸引力。这项研究于2017-2019年在波兰受STBB疫情影响的苏格兰松树为主的森林中进行。
4. 我们的研究表明，诱饵的有效性存在显着差异。由Witasek公司（奥地利）生产的实验诱饵和最近从Chemipan（波兰）出售的诱饵Acumodor Micro对STBB最具吸引力。效果最差的是迄今为止在中欧使用的两种商业诱饵（Acuwit和Acumodor）。
5. 该结果将有助于开发监测和管理STBB人群的方法。
