Results of pheromone monitoring of Dendrolimus sibiricus Chetverikov, 1908 on the territory of the Komi Republic

Collection and counting of adults of Dendrolimus sibiricus on the territory of the Komi Republic has been carried out annually since 2016 in the period from June to August by capturing males using pheromone traps. Seven forest areas located in the middle and southern taiga subzone were surveyed as part of the monitoring. More than 4000 pheromone traps of "Kvadro" type produced by the All-Russian Plant Quarantine Center (FGBU "VNIIKR") were used. Such a trap consists of a cardboard case with entomological glue on the inner surface, on which a silicone dispenser with a species-specific sex attractant - pheromone - is placed. The pheromone is a mixture of substances Z5,E7-dodecadienal and Z5,E7-dodecadienol. By analyzing the material from 2016-2022, a total of 1,618 individuals of D. sibiricus were detected and identified自2016年起，俄罗斯科米共和国境内每年6月至8月，均会通过信息素诱捕器诱捕雄性西伯利亚松毛虫（Dendrolimus sibiricus），以开展该虫成虫的采集与计数工作。本监测覆盖泰加林亚带中南部的7个林区，累计使用全俄植物检疫中心（FGBU "VNIIKR"）生产的"Kvadro"型信息素诱捕器4000余台。该类诱捕器以纸质外壳为主体，内壁涂有昆虫学专用粘胶，壳内搭载带有物种专一性性引诱剂（信息素）的硅酮分配器，其信息素成分为Z5,E7-十二碳二烯醛与Z5,E7-十二碳二烯醇的混合物。通过对2016至2022年的采集标本进行分析，总计检出并鉴定出1618头西伯利亚松毛虫个体。
