双刺云杉雕刻甲虫 Ips duplicatus 的分布范围从斯堪的纳维亚半岛和东北欧到亚洲北部。在欧洲，I. duplicatus 通常与 I 相关。云杉属的印刷，并且由于形态相似性和相似的画廊结构，I 的损害和意义。 duplicatus 通常不被识别，因此被低估。最近波兰南部、捷克共和国、斯洛伐克、奥地利北部和德国报告了重复现象；许多其他中欧国家（例如匈牙利）的记录缺失。该物种已成为中欧部分地区的重要害虫，自 20 世纪 50 年代以来，据报道中国内蒙古持续爆发这种树皮甲虫。本研究的目的是比较 I.通过线粒体 DNA 分析，通过遗传手段从欧洲和亚洲复制了复制种群。 I 的个人。收集了来自中国、波兰、捷克共和国和斯洛伐克的重复种群，并对细胞色素氧化酶I（COI）基因的520 bp片段进行了分析。检测到四种单倍型，中国和欧洲人群之间存在 0.8% 的序列差异。这些差异与两组的信息素花束和行为反应的行为差异有关。在欧洲发现了三种单倍型，但由于样本量小，没有显示出显着的地理分布。
The distribution of the double spined spruce engraver beetleIps duplicatusranges from Scandinavia and northeastern Europe to northern Asia. In Europe,I. duplicatususually is associated withI. typographusonPicea abies, and due to morphological similarities and similar gallery constructions the damage and significance ofI. duplicatusare often not recognised and thus underestimated.I. duplicatushas been recently reported from the southern part of Poland, the Czech Republic, Slovakia, northern parts of Austria and Germany; records are missing from many other central European countries (e.g., Hungary). The species became an important pest in some parts of central Europe, and continuous outbreaks of this bark beetle have been reported in Inner Mongolia, China, since the 1950s. The aim of this study was to compareI. duplicatuspopulations from Europe and Asia by genetic means using the analysis of the mitochondrial DNA. Individuals ofI. duplicatuspopulations from China, Poland, the Czech Republic and Slovakia were collected, and 520 bp fragments of thecytochrome oxidase I(COI) gene were analysed. Four haplotypes were detected and a sequence divergence of 0.8% was found between the populations from China and Europe. These differences associate with behavioural differences in the pheromone bouquet and behavioural response of the two groups. Within Europe three haplotypes were found, but due to the small sample size no significant geographical distribution was demonstrated.
