在老秃顶子国家级自然保护区共采到小蠹虫29种,隶属4亚科15属,其中红松根小蠹Hy-lastes plumbeusBlandford、东北四眼小蠹Polygraphus sachalinensisEggers、中穴星坑小蠹Pityo-genes chalcographasLinnaeus、落叶松八齿小蠹IpssubelongatusMotschuleky、六齿小蠹I.acuminatusGyllenhal等为优势种,主要危害衰弱木、濒死木、枯萎木及风倒雪压木等,少数种类如纵坑切梢小蠹Tomicus piniperda Linnaeus、黄须球小蠹Sphaerotrypes coimbatorensisStebblng等危害健康树木。不同海拔高度及不同类型的林分中,小蠹虫的种类存在明显差异。及时清除、集中处理风倒木是控制虫源,减轻危害的重要措施。
A total of 29 species of Bark beetles were found in Laodingzihuzi National Nature Reserve, belonging to 4 genera and 15 genera, among which Hy-lastes plumbeusBlandford, Polygraphus sachalinensisEggers, Pityo- genes chalcographasLinnaeus, larch IpssubelongatusMotschuleky, I. acuminatusGyllenhal and other dominant species, the main damage to weak wood, dying wood, wilt wood and wind snow pressure wood, a few species such as vertical pit cut small Beetles Tomicus piniperda Linnaeus, Bearded Beetle Sphaerotrypes coimbatorensisStebblng and other harmful health trees.
