- The aim of the study was to determine the effect of temperature and humidity on colonization of cambio−xylophagous insects on Norway spruce branches in relation to the place and method of slash utilization. Analyzed branches were infested by eight species of cambiophagous and two species of cambioxylophagous, whereas the material utilization method does not substantially influence the entomofauna species composition. The most numerous were: Pityogenes chalcographus, Ips amitinus, Dryocoetes autographus and Pityophthorus pityographus. The branches treatment was a factor contributing significantly to the infestation intensity by P. chalcographus and I. amitinus, reaching a higher density of galleries on the branches spreading disorderly on the forest floor than collected in the piles. Moreover, it was found that the location of branches inside the pile determines their attractiveness to hygrophilous species with a minor economic importance. Significant differences in temperature and relative humidity inside the piles and the surrounding branches scattered disorderly on the surface during the growing season indicate that this may be an important factor influencing logging residues left in the forest infestation intensity by bark beetles.
