Abstract: In spruce windfalls incurred in the autumn and winter season the synusia of cambioxylophagous fauna was evaluated in the profile of a whole stem and crown branches according to the species spectrum, tree cover and intensity of attack. The fauna of windfalls in the area with the basic level of Ips typographus and in the gradation area differed by species diversity. In the gradation area, frequency of the occurrence of Ips typographus (L.) was higher by 20-40%. P. chalcographus (L.) showed decreased stem cover in the gradation area. In the area with the basic state of Ips typographus, windfalls were intensively colonized by secondary species Hylurgops palliatus (Gyll.), Isarthron fuscum (Fabr.), Monochamus sp. With the increasing dbh (diameter at breast height) of windfalls the colonization of stems by Ips typographus was positively affected, H. palliatus, I. fuscum, Polygraphus poligraphus (L.) responded the other way round.
