The Panel on Plant Health performed a pest categorisation of the double-spined bark beetle, (Sahlberg, 1836) (Coleoptera: Curculionidae, Scolytinae), for the EU. is a well-defined and distinguishable species, native to Europe and attacking mainly spruce ( spp.) but also observed on pine ( spp.) and larch ( spp.). It is distributed in 15 EU Member States and is locally spreading in some of them. is listed in Annex IIB of Council Directive 2000/29/EC. Protected zones are in place in Ireland, Greece and the United Kingdom. Wood, wood products, bark, and wood packaging material are considered as pathways for this pest, which is also able to disperse by flight. The insects mostly attacks scattered individual standing trees in the stands, often when the trees are weakened by dry conditions or by pathogens, and they very rarely infest fallen or cut logs. The males produce pheromones that attract conspecifics of both sexes. Each male attracts 1-5 females and they establish a brood system; each female produces 1-60 offspring. The insects also inoculate their hosts with pathogenic fungi. There are one to three generations per year. The current geographic range of suggests that it is able to establish in most of the EU, including the protected zones, where its hosts are present. Sanitary thinning or clear-felling and pheromone trapping are the usual control methods. All criteria for consideration as potential protected zone quarantine pest are met. The criteria for considering as a potential regulated non-quarantine pest are not met since plants for planting are not viewed as a pathway.
植物健康小组对双棘小蠹（Sahlberg，1836年）（鞘翅目：象甲科，小蠹亚科）进行了欧盟有害生物分类。双棘小蠹是一个定义明确且易于区分的物种，原产于欧洲，主要侵害云杉（云杉属物种），但也在松树（松属物种）和落叶松（落叶松属物种）上被观察到。它分布于15个欧盟成员国，并且在其中一些国家正在局部扩散。双棘小蠹被列入理事会指令2000/29/EC的附件IIB。爱尔兰、希腊和英国设有保护区。木材、木制品、树皮和木质包装材料被视为这种有害生物的传播途径，它也能够通过飞行扩散。这些昆虫大多侵害林分中分散的单株立木，通常是在树木因干旱条件或病原体而衰弱时，并且它们很少侵害倒下的或砍伐的原木。雄性产生吸引两性同种个体的信息素。每个雄性吸引1 - 5只雌性，它们建立一个繁殖系统；每个雌性产生1 - 60个后代。这些昆虫还会给它们的寄主接种致病真菌。每年有一到三代。双棘小蠹目前的地理分布范围表明它能够在包括保护区在内的欧盟大部分地区定殖，只要有其寄主存在。卫生疏伐或皆伐以及信息素诱捕是常用的防治方法。双棘小蠹符合被视为潜在保护区检疫性有害生物的所有标准。由于种植用植物不被视为传播途径，所以双棘小蠹不符合被视为潜在限定的非检疫性有害生物的标准。
