Popis štitastih uši (Hemiptera: Coccomorpha) na domaćinima iz roda Quercus L. u Hrvatskoj s naglaskom na prvi nalaz štitaste uši hrasta crnike – Kermes vermilio Planchon, 1864

SažetakPopis štitastih uši na domaćinima iz roda Quercus L. sastavljen je od svih dostupnih literaturnih podataka faunističkih istraživanja štitastih uši u Hrvatskoj i podataka faunističkih istraživanja koja su trajala od 2005. do 2014. Prema literaturnim podacima u Hrvatskoj registrirano je 15 vrsta štitastih uši na hrastu. Istraživanjima je utvrđeno 12 vrsta štitastih uši, od kojih je u odnosu na vrste iz literaturnih podataka registrirano šest novih. U ovom trenutku popis štitastih uši na hrastovima obuhvaća 21 vrstu iz četiri porodice kako slijedi: porodica Asterolecanidae: Asterodiaspis ilicicola (Targioni Tozzetti 1888), A. quercicola (Bouche 1851), A. variolosa (Ratzeburg 1870), porodica Coccidae: Coccus hesperidum Linnaeus 1758, Eulecanium tiliae (Linnaeus 1758), Parthenolecanium rufulum Cockerell 1903, Pulvinaria sericea (Fourcroy 1785), porodica Diaspididae: Chionaspis etrusca Leonardi 1908, C. lepineyi Balachowsky 1928, C. salicis (Linnaeus 1758), Diaspidiotus alni (Marchal 1909), D. bavaricus (Lindinger 1912), D. ostreaeformis (Curtis 1843), D. zonatus (Frauenfeld 1868), Gonaspidiotus minimus (Leonardi in: Berlese & Leonardi 1896), Lepidosaphes beckii (Newman 1869), L. ulmi (Linnaeus 1758), Targionia vitis (Signoret 1876) i porodica Kermesidae: Kermes quercus (Linnaeus 1758), K. roboris (Fourcroy 1785) i K. vermilio Planchon 1864.U srpnju 2014. godine, zamijećeno je propadanje hrasta crnike u Poreču. Nakon što je obavljen vizualni pregled, uzeti su uzorci. Dijagnostička analiza, koja je obavljena u Laboratoriju za zoologiju Zavoda za zaštitu bilja, pokazala je da se radi o štitastoj uši crnike K. vermilio. Budući da je ovo prvi nalaz K. vermilio u Hrvatskoj, vrstu možemo smatrati novim članom hrvatske entomofaune. Ova štitasta uš napada zimzelene domaćine iz roda Quercus, ponaj­prije Quercus ilex L. Široko je rasprostranjena u zemljama Mediteranskog bazena. U prošlosti, štitasta uš K. vermilio imala je značajnu gospodarsku važnost kao izvor crvene boje z
Check-list of scale insects (Hemiptera: Coccomorpha) on host plants of genus Quercus L. comprises all available literature data on faunistic research of scale insects in Croatia, as well as data from the research conducted from 2005 to 2014. Published data on former faunistic research from the following authors have been used: Balachowsky (1950), Kovačević (1961), Kozár (1983), Langhoffer (1927, 1929), Lindinger (1912), Schmidt (1956, 1973) and Žak-Ogaza (1967). Each listed species was matched with a corresponding name, according to current systematics (Ben Dov et al., 2014). Following materials and methods were used in conducted research: visual inspections, collecting of plant material, storing and preservation of samples, analysis of samples under stereomicroscope, preparation of microscopic slides and identification of species. Samples were collected according to the method by Gill (1993). Analysis of collected samples was done under ZEISS Discovery V12 stereomicroscope with appurtenant AxioCam ERc5s digital camera. 70% ethyl alcohol, potassium hydroxide, lactic acid, fuchsine acid, lignin pink, acetic acid and clove oil were used in processing of scale insects’ samples. Permanent microscopic slides (photo 2) were prepared using clove oil, accordingly to Kosztarab & Kozár, 1988 and Gill, 1993. Identification of scale insect species was conducted using identification keys by Balachowsky, 1950, Borchsenius, 1960, Gill, 1993 and Pellizzari et al., 2012, compound microscope OLYMPUS BX 51 (with 4x, 10x, 20x, 40x and 100x magnification lens and 10x magnification ocular) and OLYMPUS DP25 digital camera. Based on literature data, 15 species of scale insects have been registered on oak trees (table 1). Faunistic investigation of scale insects in period from 2005 to 2014 established 12 species of scale insects. When compared to literature data, 6 new species have been registered (table 2). Currently, the check-list of scale insects on oak trees in Croatia comprises 21 spe
