of bark thickness, trunk diameter and height on
reproduction of the long-horned beetle, Monochamus
sutor (Col., Cerambycidae) in burned larch and pine.

The small white-marmorated longicorn, Monochamus sutor L., is one of
the most prevalent stem-infesting insects in burned areas of the
Great Xing An Mountains, China. Burned trees of larch (Larix
dahurica) and pine (Pinus sylvestris var. mongolica) are suitable for
reproduction by M. sutor from the trunk base to within an average of
3.3 and 4.6 m from the top, respectively, for trees from 13-23 m in
height. The emergence of M. sutor gradually declines with height, and
ceases at a bark thickness of less than 0.3 cm in both species.
Emergence increased in a logarithmic relationship with either bark
thickness or trunk diameter in both tree species. Two linear
regression equations, Y = 2.01 + 0.426X and Y = 0.07 + 0.771X, were
derived in order to predict the average density of M. sutor emergence
per 0.1 m2 bark area (Y) for the trunk based on an observed density
(X) at breast height position (1.5 m) for larch and pine,
respectively. The total number emerging from a tree can be predicted
by multiplying the average density estimate by the expected
reproduction bark area. Reproduction of cerambycids is discussed with
respect to selection of host trees, interactions with guild species,
effects of bark thickness, and forest fire dynamics.
