(Coleoptera, Scolytidae). Therefore it was assumed that the abundance of these bark beetles in the reserves was high and that they dispersed to the surrounding spruce forests. To verify this opinion, their population levels were monitored in the strict reserve Jankove Bare and the adjoining spruce forests over the period 2006-2008. I. typographus parasitoids were identified and the parasitism percent was determined in spruce forests around the reserves. Throughout the monitoring period, the abundance of I. typographus and P. chalcographus was found to be lower in the reserve than in the surrounding spruce forests. Five species of I. typographus parasitoids and a low parasitization percent were identified in spruce forests surrounding the reserve.10aIps typographus10aPityogenes chalcographus1 aMarkovic, Cedomir1 aStojanovic, Aleksandar  uhttps://weevil.myspecies.info/differences-bark-beetle-ips-typographus-and-pityogenes-chalcographus-abundance-strict-spruce-reser-001678nas a2200181   4500008004100000020001400041245016000055210006900215260000800284300001000292490000700302520095400309653002001263653002901283100002201312700002701334856013501361       2010                        eng d  a0334-212300aDifferences in bark beetle (Ips typographus and Pityogenes chalcographus) abundance in a strict spruce reserve and the surrounding spruce forests of Serbia0 aDifferences in bark beetle Ips typographus and Pityogenes chalco  cFeb  a31-370 v383 aFrequent windthrow in the strict reserves of spruce in the Kopaonik National Park provides much material favorable for the development of Ips typographus (L.) and Pityogenes chalcographus (L.)
