Phyllonorycter issikii (Lepidoptera: Gracillariidae) has recently spread over a considerable part of the Eurasian continent. So far, in Europe, unlike in russia, it has not significantly affected its food plant (Tilia cordata), but its effect may increase over time. The regulating potential of associated parasitoid natural enemies is still low, which probably allows further leaf miner range expansion and population growth. This species is potentially capable of inflicting considerable damage on its host. Therefore, it is important to study its natural enemies, especially their oviposition behaviour and biology. In this paper, we summarize the results of rearing experiments throughout the area it has recently occupied, including our own study in Hungary. Here we list 46 species of parasitoids recorded from P. issikii. None of these species are likely to be able regulate the abundance of P. issikii. Further studies are needed to determine their effect on the abundance of this host.
-251 Rubus leaves mined by three species of leaf miners, Metallus pumilus (Klug, 1816), Emmetia heinemanni (Wocke, 1871) and Ectoedemia rubivora (Wocke, 1860), were collected between 2011 and 2014 in order to rear out their parasitoids. No parasitoids have been reared out from Ectoedemia rubivora, but we have identifi ed 3 parasitoid species from Emmetia heinemanni and 5 species from Metallus pumilus. With 2 tables.
Four new species of cynipid herb gallwasps, Aulacidea tavakolii Melika, new species; Isocolus freidbergi Melika, new species; Isocolus beheni Melika & Karimpour, new species and Isocolus karimpouri Melika & Tavakoli, new species (Hymenoptera: Cynipidae: Aylacini) from Iran and Israel are described. Data on the diagnosis, distribution and biology of the new species are given. Seven species of aylacine gallwasps were known from the Middle East. One species, Isocolus centaureae Diakontschuk, reported for the first time from this region.
-Between 2011 and 2014, 1,154 mines of Phyllonorycter comparella (Duponchel) were collected at 12 locations in Hungary and were put into single-mine rearing containers. A total of 574 parasitoid specimens belonging to 29 parasitoid species (26 Chalcididae, 2 Encyrtidae and 1 Braconidae) emerged. Of these species, 13 have not yet been mentioned in either international or in Hungarian literature as a parasitoid of the P. comparella. The species assemblages of the parasitoid complexes varied greatly among the sample sites. The primary dominant species of the total samples was found to be Sympiesis sericeicornis (Nees), an abundant idiobiont solitary ectoparasitoid. Among the species reared, we have found specialist parasitoids such as Achrysocharoides scaposa (Erdős) and even species never recorded from Populus (Zagrammosoma variegatum (Masi)) according to the Universal Chalcidoidea Database.
Phyllonorycter comparella / Populus alba / parasitoid assemblagesKivonat -A Populus alba-n élő Phyllonorycter comparella (Lepidoptera: Gracillariidae) levélaknázó magyarországi parazitoid együttesei. 1154 Phyllonorycter comparella (Duponchel) levélaknát gyűjtöttünk és tettünk egyedi nevelésbe 2011-2014 között, 12 Magyarországi helyszínről. A nevelésből kikelt 574 parazitoid egyed alapján 29 fajt (26 Chalcididae, 2 Encyrtidae és 1 Braconidae) sikerült azonosítani. Ezek közül 13 fajt sem a nemzetközi sem a hazai szakirodalom korábbról nem említ, mint a P. comparella parazitoidjait. Különböző mintagyűjtési helyszínek parazitoid komplexum fajegyüttesében eltérések mutatkoztak. A teljes minta elsődleges domináns faja a Sympiesis sericeicornis (Nees), egy gyakori idiobiont szoliter ektoparazitoid volt. A nevelésből kikelt fajok között olyan specialista fajokat is azonosítottunk, mint az Achrysocharoides scaposa (Erdős) valamint Populusról eddig, a Nemzetközi Chalcidoidea Adatbázis (Universal Chalcidoidea Database) által még nem regisztrált Zagrammosoma variegatum (Masi) parazitoid fajt is.
