Stanje, potencialni vplivi in možnosti obvladovanja hrastove čipkarke v hrastovih gozdovih v Sloveniji

Mineva šest let od prve najdbe invazivne tujerodne hrastove čipkarke (Corythucha arcuata) v Sloveniji, ki se že širi po vsej državi. V zadnjih letih je bilo ugotovljeno, da v slovenskih gozdovih gozdarji vrsto že prepoznavajo kot problematično. Negativni vplivi hrastove čipkarke se kažejo v rjavenju krošenj in zmanjšanju stopnje fotosinteze. Dolgoročni vplivi vrste na hraste in različne druge organizme, povezane s hrasti, pa še niso dobro raziskani. Trenutno potekajo tudi raziskave o možnostih zatiranja tega škodljivega organizma. Pripravili smo povzetek biologije, vplivov in raziskav o možnostih obvladovanja hrastove čipkarke. Za boljše razumevanje širjenja in vpliva hrastove čipkarke v slovenskih gozdovih vas vabimo k sodelovanju in sporočanju opažanj v informacijski sistem Invazivke (www.invazivke.si). It has been six years since the invasive oak lace bug (Corythucha arcuata) arrived in Slovenia and is slowly spreading over large parts of the country. Recent surveys have shown that foresters recognise that the oak lace bug is a problem for Slovenian forests. The effects are mainly a browning of the tree crowns and a decrease in photosynthesis. The longterm consequences for the trees and the interactions between other oak-related species are not yet well understood. There is research going on on different management options. We have prepared an article providing an overview of the biology, impacts, and research on control options. To better understand the spread and impact of the oak lace bug, we invite you all to submit your observations to the information system “Invazivke” (www.invazivke.si).
