Ambrozijski podlubnik (Curculionidae Scolytinae, Xylosandrus germanus) v revirju Šentvid

Pajek, Luka (avtor), Jurc, Maja (mentor)

Tujerodni črnolesni ambrozijski podlubnik Xylosandrus germanus je bil v Sloveniji prvič najden leta 2000 v okolici Nove Gorice, med letoma 2008 in 2010 pa je bila vrsta najdena tudi na več lokacijah v okolici Ljubljane. Glavni namen naše naloge je bil potrditi prisotnost in ugotoviti velikost populacije X. germanus v revirju Šentvid (Krajevna enota Škofljica). Spremljanje vrste smo izvajali s pastmi iz odpadnih plastenk, ki smo jih naredili sami. Pasti so bile postavljene v treh različnih gozdnih sestojih, in sicer smo v vsakem sestoju postavili 4 pasti z različnimi atraktanti (etanol, denaturiran etanol, kombinacija etanola in ?-pinena ter kontrolna past brez atraktanta). Pasti smo spremljali osem tednov, v obdobju med 26.4.2017 in 20.6.2017, jih tedensko praznili, ulov pa determinirali v Laboratoriju za varstvo gozdov, Oddelka za gozdarstvo in obnovljive gozdne vire BF. Potrdili smo prisotnost X. germanus v revirju Šentvid (KE Škofljica). Ujeli smo 11.460 osebkov vrste X. germanus, kar je v skupnem ulovu predstavljalo kar 90,09 % celotnega ulova hroščev oziroma 95,30 % celotnega ulova podlubnikov. Naši rezultati kažejo, da ni večjih razlik v učinkovitosti privabljanja vrste X. germanus med testiranimi atraktanti, glede na število ujetih osebkov X. germanus pa lahko trdimo, da so tudi doma narejene pasti iz odpadnih plastenk primerno orodje za izvajanje monitoringa tujerodnih ambrozijskih podlubnikov.

Izvleček

In Slovenia the presence of the non-native Black timber bark beetle (Xylosandrus germanus) was first recorded in the vicinity of Nova Gorica yet in the period between 2008 and 2010 the species was already detected on several locations in the vicinity of Ljubljana. The main aim of the current BSc thesis was to confirm the presence and determine the actual population density of X. germanus in Šentvid forest district (Škofljica regional unit). Population monitoring was conducted via the trapping system incorporating disposable plastic bottles which were designed by the author of the thesis. Four traps were deployed in each of the three selected forest stands where the targeted populations were lured by various attractants (ethanol, denatured ethanol, a blend of ethanol and α-pinene, un-baited control traps). The traps, which were monitored within the period of eight weeks, i.e. between 26th April 2017 and 20th June 2017, were emptied on a weekly basis, and the catch was subsequently determined in the Laboratory for Forest Protection at the Department of Forestry and Renewable Forest Resources BF. The analysis confirmed the presence of the non-native X. germanus beetle within the targeted sites. A total of 11,460 X. germanus individuals were collected, which comprised 90,09 % of all the captured beetles (Coleoptera) specimens, or 95,30 % of all captured bark beetle specimens. No significant differences were established in the attractiveness rates among the employed attractant agents. The large number of collected X. germanus specimens undoubtedly confirms that home-made traps from disposable plastic bottles represent a suitable monitoring tool for the non-native bark beetle population.
