云杉大黑天牛是鞘翅目,天牛科,是我区木材的主要害虫。此种害虫在贮木场,采伐迹地等危害甚烈。我们利用有效积温预测法,历期预测法较为准确的对卵期、幼虫期以及对各个虫态的发生时间及始盛期、高峰期等进行了预报。在此基础上,我们对成虫进行了化学药剂击避及灭卵防治收到很好的防治效果,木材损失率降低了9.7％,木材等级有了提高。 Spruce Larvae is Coleoptera, Cerambycidae, is the main pests of timber in our area. Such pests in the storage yard, deforestation and other endangered. We use the effective temperature prediction method, the period prediction method is more accurate on the egg stage, larval stage, as well as the occurrence of each state and the beginning of the peak, peak and so on were predicted. On this basis, we have achieved good results in prevention and control of adult insects by chemical agents, a reduction of 9.7% in wood loss and an increase in wood grades.
