雅库特苏维埃社会主义自治共和国的森林主要是由兴安落叶松(Larix dahurica Turcz.)组成。这个树种的天然更新常受到许多因子的影响,而种子害虫是重要的因子之一。在雅库特森林生长极慢的情况下,落叶松林的伐前更新具有很大的意义,因为这可使森林培育的时间缩短15～20年。本文所用的资料是苏联科学院西伯利亚分院林业 The forest of the Yakutia Autonomous Community of Soviets consists mainly of Larix dahurica Turcz. Natural regeneration of this tree is often affected by many factors, and seed pests are one of the important factors. In the case of very slow growth in the Yakutia forest, pre-harvest regeneration of the larch forest is of great significance, as it can shorten the period of forest cultivation by 15 to 20 years.
