Abstract

The growth of Pinus tabulaeformis is influenced by the sonsau cocuus sinensis chen. When the insect density is more than 300-350 head/hundred beam conifer, sonsau cocuus sinensis chen occurred significantly influence the Pinus tabulaeformis s growth. When the insect density reached 250-300 head/100 beam coniferous, sonsau cocuus sinensis chen significantly influence the accumulation of Pinus tabulaeformis volume. To determine the sonsau cocuus sinensis chen 2nd instar nymph theory control index was 220.5 /hundred beam needles has a guiding significance to the production practice.
