| Popis: | Prispevek je prvi v seriji prispevkov, ki bodo obravnavali zdravje gozda. Namenjena je gozdarjem v operativnem gozdarstvu za uspešnejše delo v slovenskiPoročevalski, diagnostični in prognostični službi. Opisani bodo najpomembnejši škodljivi biotski (žuželke, glive, bakterije, virusi, ogorčice,mali sesalci) in abiotski dejavniki (suša, požar, pozeba). Razporejeni bodo po pomembnosti z ozirom na ekonomske škode in po drevesnih vrstah na katerih se najpogosteje pojavljajo. V prvem delu prispevka prikazujemo štiri vrste podlubnikov na navadni smreki (Picea abies): osmerozobega smrekovega lubadarja (Ips typographus), šesterozobega smrekovega lubadarja (Pityogenes chalcographus), dvojnookega smrekovega ličarja (Polygraphus poligraphus) ter malega osmerozobega smrekovaga lubadarja (Ips amitinus). Na kratko je prikazana njihova morfologija, bionomija, opis poškodb, morebitne zamenjave, gostitelji, vzroki za nastanek in nadaljevanje gradacij ter ogroženost sestojev. Za najpomembnejše vrste je opisana tudi kontrola gostote populacije in zatiranje, našteti so njihovi najpomembnejši naravni sovražniki. The present contribution is the first in a series which will deal with forest health. It is designed for foresters in practice and aimed at a more efficientperformance of the Reporting, diagnostic and prognostic service in Slovenia. The most important harmful biotic factors (insects, fungi, bacteria,viruses, nematodes, small mammals) and abiotic factors (drought, fire, frost) will be presented. They will be arranged by their importance withregard to economic importance and by the host on which they most often appear. In the first contribution we present four species of bark beetles on Norway spruce (Picea abies): the eight-toothed spruce bark beetle (Ips typographus), six-toothed spruce bark beetle (Pityogenes chalcographus), smallspruce bark beetle (Polygraphus poligraphus) and small eight-toothed spruce bark beetle (Ips amitinus). A short description of their morphology, bionomy, a description of damages, possible misidentifications, hosts, causes of beginning or continuation of their outbreaks and their threat to forests isgiven. For the most important species control of population density and suppression are also described, and their most important natural enemies are listed. |
