Gradacija sipaca Ips typographus (L), Pityogenes chalcographus (L) i Xyloterus lineatus (Oliv) (Coleoptera, Scolytidae) na Staroj Planini

Abstract

Nakon velikih vetroloma u šumama smreče na Staroj Planini, koje su se desile u periodu 1997-2002. godine, u gazdinskim jedinicama "Stara Planina II Arbinje" i "Stara Planina II - Topli do", došlo je do gradacije sipaca, I. typographus, P. chalcographus i X. lineatus. Kako je Stara Planina park prirode, njihovo suzbijanje obavljeno je primenom feromona (IT Ecolure, PC Ecolure i XL Ecolure). Upotrebom navedenih preparata ulovljeno je 5,014.361 imago navedenih vrsta sipaca. Međutim, i pored toga, gradacija na Staroj Planini nije prekinuta. Zbog toga će se sa suzbijanjem, primenom istih feromona, nastaviti i narednih godina.

Severe windblows in spruce forests on Stara Planina, occurring in the period 1997-2002, in the management units "Stara Planina II - Arbinje" and "Stara Planina II - Topli do", were followed by the outbreaks of bark beetles I. typographus, P. chalcographus and X. lineatus. As Stara Planina is a Nature Park, their suppression was performed by the application of feromones (IT Ecolure, PC Ecolure and XL Ecolure). 5,014,361 adult bark beetles of the above species were caught by the above preparations. However, still the outbreak on Stara Planina was not controlled. Consequently, the suppression with the same feromones will be continued in the following years.
