Abstract

Najznačajniji štetnici platane su mrežasta stjenica platane - Corythucha ciliata (Say, 1833) i platanin moljac miner - Phyllonorycter platani (Staudinger, 1870). Najznačajniji štetnik divljeg kestena je kestenov moljac miner - Cameraria ohridella (Deschka et Dimić, 1986). Ovi štetnici negativno utječu na zdravstveno stanje i vitalnost stabala domaćina. Posljedično štetama, narušene su funkcije gradskog zelenila u urbanom ekosustavu. Cilj ovog istraživanja bio je utvrditi vrijeme pojave i brojnost imaga i ličinki mrežaste stjenice platane, plataninog moljca minera i kestenovog moljca minera na području zagrebačke Dubrave. Istraživanje je provedeno od kraja travnja do sredine kolovoza u 2021. godini. Štetnici platane utvrđivani su na tri lokacije. Brojnost kestenovog moljca minera utvrđivana je na četiri lokacije. Dodatno, u vrtu Zavoda za zoologiju na Agronomskom fakultetu Sveučilišta u Zagrebu, postavljena je feromonska lovka kojom se pratio let mužjaka leptira kestenovog moljca minera. Tijekom istraživanja determinirani su svi štetnici. Svakih 14 dana pregledavani su listovi platane i divljeg kestena. Sa 10 stabala uzimano je po 10 nasumičnih listova, ukupno 100 listova za svaku vrstu. Ukupno je provedeno 9 pregleda. Brojnost mrežaste stjenice platane bila je najveća u Dankovečkoj ulici. Brojnost pronađenih stadija plataninog moljca minera bila je preniska za izvođenje konkretnih zaključaka. Brojnost kestenovog moljca minera redovito je bila najveća na stablima Športsko-rekreacijskog centra Grana-Klaka. Brojnost mužjaka leptira bila je najviša u zadnjem pregledu 16. kolovoza. Najniža brojnost štetnika platane i divljeg kestena bilježena je u Parku Diane Budisavljević. Provedenim istraživanjem utvrđeno je da mrežasta stjenica na području zagrebačke Dubrave razvija dvije generacije, a kestenov moljac miner tri generacije godišnje.

Abstract (english)

The most important pests of London plane tree are sycamore lace bug - Corythucha ciliata (Say, 1833) and leaf miner - Phyllonorycter platani (Staudinger, 1870). The most important pest of horse-chestnut tree is horse-chestnut leaf miner - Cameraria ohridella (Deschka et Dimić, 1986). Those pests have negative impact on health and vitality of host trees. Due to damages, functions of urban greenery in urban ecosystem are violated. The purpose of this research was to determine number and population dynamics of sycamore lace bug, sycamore leaf miner and horse-chestnut miner in Dubrava, district of Zagreb. The research was conducted from the end of April to middle August in 2021. Pests of London plane tree were determined in three locations. Number of horse-chestnut leaf miner was determined in four locations. Additionally, pheromone trap for monitoring male horse-chestnut leaf miners was set in garden of Department of Agricultural Zoology, Faculty of Agriculture, University of Zagreb. During the research all pests were determined. Leaves of London plane tree and horse-chestnut were examined every 14 days. The research was conducted by examining 10 randomly selected leaves on 10 trees, totaling at a number of 100 leaves altogether for both tree species. 9 examinations were conducted. Number of sycamore lace bug was highest in Dankovečka street. Population of Ph. platani was too low for deriving solid conclusions. The highest population of horse-chestnut miner was regularly in Sports and recreational facility Grana-Klaka. Number of adult male horse-chetsnut moths was highest on August 16. Lowest number of Lodnon plane tree pests and horse-chestnut pests was recorded in Park of Diana Budisavljević. Sycamore lace bug developed two generations, while horse-chestnut leaf miner developed three generations in investigated area.
