    Description

    Insects not only use plants for food and habitat; they also change plant populations by influencing their structure and dynamics. This influence is evidenced in the alteration of the spatial structure of a stand. The fir sawyer, Monochamus urussovi Fisch. (Coleoptera: Cerambycidae), is the most abundant xylophagous insect injuring siberian fir, Abies sibirica Ledeb. It dominates both in outbreak and non-outbreak areas. The beetles influence the structure and dynamics of fir stands by damaging tree crowns during adult feeding. At high population density this damage eventually determines the spatial structure of the fir stands.
