Az Eriococcidae pajzstestű család fontosabb nemeinek világreviziója = World revision of the most important genera of the Eriococcidae family
Az Eriococcidae családot 50 ország anyagán tanulmányoztuk. Magyarország 526 helyén végeztünk gyűjtéseket (1140 minta), 180 tartalmazott Eriococcidae-kat. Gyűjteményünk 130 fajjal gazdagodott. 9 új génusz és 27 új faj került leírásra, és publikálásra. A készülő Palaearktikus művünk a 18 génuszból ismert 175 faj helyett 27 nemből 195 fajt tartalmaz. Új fajok lelőhelyei: Ausztria, Kanári sz., Ciprus, Spanyolország, Törökország, Ausztrália, Új Guinea, Sulawesi, Fülöp sz., Brazília, Chile, Paraguay, Venezuela. Több új határozást segítő morfológiai bélyeget is találtunk. Az Acanthococcus aceris faj molekuláris etalonjaként is a magyar példányt használják a világon. Új hipotézisként jeleztük az Új-Zéland-Pacifikus-Orientális-Palaearktikus terjedési útvonal fajképzésben játszott szerepét. A tápnövény specializációban e családnál a polifágiára való hajlam hipotézise elvethető és fajok keletkezési trendje a Jermy féle szekvenciális evolúció hipotézisével írható le. A kladisztikai elemzések alapján a Palaearktikumban használt génuszok jól elkülönülnek, sőt további kisebb csoportokat is alkotnak. A pajzstetvek elterjedését bemutató könyvünk 7 génuszban 25 Eriococcidae-t tartalmaz. A felderítések során bükkön a Cryptococcus fagisuga, a Pseudochermes fraxini kőrisfákon, a Gossyparia spuria szilfákon, és az Acanthococcus aceris juharfákon fordult elő káros mértékben. Karantén vizsgálataink során hazánkban nem került elő Eriococcidae faj. | The Eriococcidae scale insect family collection material of 50 country was analysed. In Hungary surveys were made in 526 localities (1140 samples), 180 contains eriococcids. 130 species new for collection. Nine new genera and 27 new species were described. Our Palaearctic monograph instead of 175 species in 18 genera will contain 195 species in 27 genera. New species appeared in the next countries: Austria, Canary Isl., Cyprus, Spain, Turkey, Australia, New Guinea, Sulawesi, Philippine Isl., Brazil, Chile, Paraguay, Venezuela. Several new morphological character was found, too. As a molecular standard the samples collected by me in Hungary of Acanthococcus aceris is used all over the world. As a new hypotheses the New Zealand-Pacific-Oriental-Palaearctic rout of dispersal is proposed as a possibility for species formation. In host plant specialisation the polyphagy hypotheses was not supported, and instead the Jermy?s sequential evolution is acceptable. On the base of the cladistic analyses was established, that the used genera in the Palaearctic Region well separated, and smaller groups are seen too. The book on distribution of scale insects in Hungary included 25 species in 7 genera of Eriococcidae. In the species surveys in Hungary we found that Cryptococcus fagisuga on Fagus, Pseudochermes fraxini on Fraxinus, Gossyparia spuria on Ulmus, and Acanthococcus aceris on Acer were present as pest. In quarantine surveys we did not find Eriococcidae
NEW AND LITTLE KNOWN SCALE INSECT SPECIES (HEMIPTERA: COCCOIDEA) IN TURKEY
Scale insects (Hemiptera: Coccoidea) are notorious pests, especially of perennial plants.
They are serious pests of fruit and nut trees, ornamental shade trees and shrubs, forest trees, greenhouse and indoor plantings. In the present study, new data are given for 13 species of scale insects from Turkey as follows: Coccidae (1 sp.), Cerococcidae (1 sp.), Diaspididae 2 spp.), Pseudococcidae (8 spp.) and Rhizoecidae (1 sp.). Chorizococcus malabadiensis
Kaydan sp. n. is described and illustrated as a new species and 8 species are recorded for the first time from Turkey
A new species of Greenisca and two new species of Ovaticoccus from Italy (Hemiptera Coccoidea Eriococcidae), with a key to European genera of Eriococcidae.
Three new eriococcid species from Italy are described and illustrated, namely Greenisca oreophila sp. n. off Poaceae, and Ovaticoccus exoticus sp. n. and O. agavacearum sp. n., off Agavaceae. Their morphological relationships are discussed and keys to Greenisca and Ovaticoccus species are provided, together with a key to the Eriococcidae genera so far known in Europe. A check-list of Italian Eriococcids is added
Pajzstetű fajok morfológiai és molekuláris összehasonlító vizsgálata
A pajzstetvek széles körben elterjedt növényi kártevôk. A fajok meghatározása ivarérett nôsténybôl
készült mikroszkópi preparátum alapján történik. Molekuláris módszerekkel a fajszintû azonosítás
nemcsak nôstény egyedek, hanem tojások, lárvák vagy hím egyedek esetében is lehetséges.
Munkánk során morfológiai és molekuláris összehasonlító vizsgálatokat végeztünk az eperfapajzstetû
Pseudaulacaspis pentagona (Targioni-Tozetti, 1886) (Diaspididae) és két Planococcus
(Pseudococcidae) fajon. Célunk, hogy a P. pentagona faj esetében mikropopulációs különbségeket,
a Planococcus nemzetség esetében pedig a fajok közti genetikai eltéréseket tegyük láthatóvá molekuláris
markerek segítségével. Molekuláris módszerekkel meghatároztuk a riboszomális DNS ITS2
szakasz bázissorrendjét. A kapott eredmények alapján feltételezhető, hogy a mikropopulációkat nagyobb
mértékben befolyásolják a területi elkülönülések, mint a tápnövény. Az ITS2 régió alkalmas
a két Planococcus faj elkülönítésére, melyek a szekvenciák alapján rajzolt törzsfán egyértelmûen elkülönülnek
egymástól. A molekuláris és morfológiai vizsgálatok mindkét faj esetében ugyanarra az
eredményre vezettek. A molekuláris módszer alkalmas mind hím, mind nôstény imágók esetében a
fajok elkülönítéséhez
Records of Ceroplastes Gray 1828 in Europe, with an identification key to species in the Palaearctic Region
Abstract The genus Ceroplastes (Hemiptera Coccoidea Coccidae) in Europe is reviewed. Surveys of Hungarian nurseries, greenhouses and flower shops found plants infested with Ceroplastes scale insects. Among them, Ceroplastes rubens Maskell 1893 was identified. Since there is constant invasion of European markets by species of Ceroplastes, a key is presented to separate the species currently known to occur in the Palaearctic Region

Brazil, Rio Grande do Sul; Paraguay, Asuncion; Venezuela, Merida, all on Psidium guajava or Psidium sp. (Myrtaceae). Comment. E. maximus is similar to E. perplexus Hempel, 1900, sharing with it a similar arrangement of dorsal spinose setae, the presence of frontal lobes and the large body size. However, E. perplexus has much smaller spines on the mid-dorsum of the posterior abdominal segments (each about 5 times shorter than the larger marginal spinose setae), whereas those in this position on A. maximus are only 2 times shorter than those on the margin. In addition, the coxal pores on E. maximus are larger and more abundant (about 40–45) than on E. perplexus, which has smaller and fewer pores (about 20). E maximus also differs from E perplexus in having a band of about 15–22 cruciform pores on each side between the anterior and posterior spiracles, whereas these are absent on E. perplexus. E. maximus differs from E. longisetosus in having short ventral hair-like setae; from E. paranaensis in the abscence of groups of microtubular ducts on dorsum; from E. christopherus in the random distribution of spine-like setae on dorsum, and from E. venezuelaensis in the presence of frontal lobes and twice as many cruciform pores.Published as part of Foldi, Imre & Kozár, Ferenc, 2007, New species and new records of Eriococcus (Hemiptera, Coccoidea, Eriococcidae) from South America, pp. 51-64 in Zootaxa 1573 (1) on pages 56-58, DOI: 10.11646/zootaxa.1573.1.3, http://zenodo.org/record/509671

Body widest across segment I. Body membranous, except for sclerotised pygidium. Venter: Each antenna with 3 large setae and 2 short conic setae. Anterior spiracles each with one associated trilocular disc pore; posterior spiracles without disc pores. Pygidium rounded, slightly sclerotized, with 2 pairs of lobes. Median lobes with space between them as wide as one of them (length of L 1 lobes 29 (23–29) µm wide, space between lobes 33 (21–35) µm wide); (L 1) prominent, rounded, outer margin slightly notched. Second lobes (L 2) unilobular, similar in shape to median lobes but smaller and not notched; L 3 barely perceptible, triangular and finely pointed. Gland spines twice the length of median lobes, each long and slender with a broad base; present as follows: with 2 between median lobes, 2 between L 1 and L 2, and 3 laterad to L 2. Ventral macroducts smaller than dorsal macroducts, present in a submarginal group on segments I and II. Posterior spiracles each with 3 or 4 glandular tubercles and 7 or 8 macroducts in a transverse band extending to margin. Similar macroducts present on submargin of prothorax and mesothorax. Microducts few, present on head and thorax, and with smaller ducts on abdomen. Perivulvar disc pores in 5 groups as follows: 0–3 in median, 5–8 in anterolateral, and 4–8 in posterolateral group. Dorsum. With 1 marginal macroduct on pygidium on each of segments IV–VII (formula 1,1,1,1). Submarginal macroducts: 2 on segments IV and V each, and 5 or 6 on segments I–III each. Submedian macroducts: 1 on each of segments I–VI. Macroducts also present around submargin of metathorax and with smaller ducts on head, mesothorax and prothorax. Anal opening near anterior margin of pygidium on segment of V. Comment. This species is characterized in having the following combination of morphological characters: (a) 3 large setae and 2 short conic setae on each antenna, (b) a band of glandular tubercles near each posterior spiracle, (c) unilobular L 2 lobes, (d) single marginal macroducts on each of segments IV–VII, and (e) presence of 1 pair of gland spines between the median lobes, 2 between L 1 and L 2, and 3 laterad to L 2. T. turcica resembles T. cedricola comb. nov. in having most of the above characters, but the latter differs in having: (a) only 2 setae on each antenna, (b) bilobed L 2 lobes, (c) only 1 gland spine between L 1 and L 2, and (d) more median and submedian macroducts dorsally on abdominal segments I–III. T. turcica is also similar to T. farsianus comb. nov., both having: (a) 1 marginal macroduct on each of segments IV–VII, and (b) gland tubercles near each anterior spiracle, but the latter species differs in having: (a) L 2 bilobed, (b) no perivulvar disc pores, (c) 1 gland spine between L 1 and L 2, and laterad to L 2, and (d) absence of macroducts submarginally on thorax and head. Etymology. The genus name is formed from Toros (in honour of Prof. Dr. Seval Toros, Ankara, Turkey, a famous lady Turkish aphidologist and entomologist) and aspis, Greek, meaning shield, often used to name members of the Diaspididae.Published as part of Ülgentürk, Selma & Kozár, Ferenc, 2011, A new scale insect genus, Torosaspis (Hemiptera: Sternorrhyncha: Coccoidea: Diaspididae), with a new species, Torosaspis turcica, from Turkey, pp. 63-68 in Zootaxa 2907 on pages 64-67, DOI: 10.5281/zenodo.20235
