Smrekovi podlubniki (Coleoptera: Scolytidae) v Gozdnogospodarski enoti Medvode v letu 2004

Naloga obravnava dinamiko razvoja in številčnost populacije osmerozobega smrekovega ubadarja Ips typographus (L.) in šesterozobega smrekovega lubadarja Pityogenes alcographus (L.) (Coleptera: Scolytidae) v gospodarski enoti Medvode. Ulov ßmrekovih podlubnikov in ulov neciljnih vrst členonožcev smo spremljali na različnih okacijah, legah in nadmorskih višinah s pomočjo kontrolno-lovnih pasti Theysohn in eromonskimi vabami Pheroprax in Chalcoprax. Vzorčili smo od marca do vključno ßeptembra leta 2004, vremenske podatke za meteorološki postaji Ljubljana in Brnik pa ßmopridobili na Agenciji za okolje republike Slovenije. Poleg obeh ciljnih vrst odlubnikov, ki se v največji meri ujameta v kontrolno-lovno past smo spremljali tudi lov drugih neciljnih vrst žuželk in ostalih členonožcev. S korelacijsko analizo smo gotovili, da obstajajo negativni korelaciji med ulovom velikega osmerozobega ßmrekovega lubadarja in nadmorsko višino ter povprečno mesečno relativno vlago zraka n negativni korelaciji med šesterozobim smrekovim lubadarjem in povprečno mesečno elativno vlago zraka in pozitivna korelacija med šesterozobim smrekovim lubadarjem in ovprečno mesečno temperaturo zraka.The graduation thesis deals with the dinamics of development and number of population spruce bark beetle Ips typographus (L.) and spruce bark beetle Pityogenes alcographus (L.) (Coleoptera: Scolytidae) in the forest management unit Medvode. he catches of spruce bark beetles and other species of Arthropoda were investigated on ifferent locations, sites and sea-heights withPheroprax- and Chalcoprax-baited heysohn slot traps. We were sampling frommarch to including september in 2004. The eather data for the meteorologicstations Ljubljana and Brnik were acquired on Agency or environment in the repulic of Slovenia. Among both spruce bark beetles were cathed n the Theysohn slot traps other insects and Arthropods. A correlation analysis has shown hat there are negative correlations beetwen catches of Ips typographus (L.) and sea eights and average monthly relative humidity and negative correlation beetwen catches Pityogenes chalcographus (L.) and average monthly relative humidity. On the other and a rrelation analysis has shown a positive correlation beetwen catches of ityogenes chalcographus (L.) and average monthly temperature of air
