    Description

    Intensive logging of pine and spruce forests in Estonia has led to a rapid increase in the populations of some insect species. A survey using ground traps baited with a blend of turpentine and ethanol resulted in the recovery of large numbers of the large pine weevil, Hylobius abietis, as well as bark beetles of the genus Hylastes. During an 11-year study (1990-2000) carried out in reforestation areas of Estonia, a total of 61,721 insect specimens were captured. The percentages of trapped insects were as follows: Hylobius abietis 65.6%, Hylobius pinastri 0.5%, Hylastes brunneus 17.8%, Hylastes opacus 5.3%, Hylastes cunicularius 0.5%, and all other insect species 10.3%. In newly created clear cuttings, an average of 1124 individuals of Hylobius abietis were caught per trap in 1999. The associated bark beetle species Hylastes brunneus and Hylastes opacus were more abundant in the second year after felling; the mean numbers of individuals caught per trap were 309 and 94, respectively.
