Abstract

Naloga obravnava vpliv standardnih populacijskih feromonov (Pheropraxr, Chalcopraxr in Curviwitr) na vrsto Ips amitinus (E.). Raziskava je potekala v Krajevni enoti Dravograd. Ulov smrekovih podlubnikov ter naključnostni ulov smo spremljali na treh lokacijah z različno ekspozicijo in nadmorsko višino ins pomočjo kontrolno-lovnih pasti Theysohn. Na vsaki izmed lokacij so bile v vodoravni liniji postavljene po 4 pasti v razmiku po 4 m. Pasti so bile opremljene s po enim populacijskim feromonom, četrta past pa je bila brez feromona in je služila kot kontrola. Ulov smo spremljali v času od 11. junija do 22. septembra 2005. Vremenske podatke za Meteorološko postajo Slovenj Gradec smo dobili na Agenciji za okolje Republike Slovenije. Ugotovili smo, daimajo prej omenjeni feromoni minimalen vpliv na vrsto Ips amitinus, večji vpliv je imel feromon Pheropraxr. Za kontrolo gostote populacije je bilo učinkovitejše polaganje kontrolno-lovnih dreves.

Secondary abstract:	This thesis discusses the influence of the prevailing population pheromones (Pheropraxr, Chalcopraxr and Curviwitr) on the Ips amitinus (E.) species. The research was carried out in local unit Dravograd. The catches of spruce bark beetles and random catch were monitored at three locations of different exposition and different heights above sea level, using Theysohn's controlcatch traps. On each location, four traps were set in a horizontal linewith a span of four metres. Three of them were equipped with an individualpopulation pheromone, the fourth contained no pheromone, serving as a check. The catch was supervised over the period of 11/06 to 22/09/2005. The weather data of the station Slovenj Gradec were obtained from the Environmental Agency of the Republic of Slovenia. We have come to the conclusion that the above-mentioned pheromones have a minimal effect on the Ips amitinus (E.) species, the strongest being that of Pheropraxr. For the purpose of population density check, control catch trunks have proved more effective.
