Melika, G., Csóka, Gy. , Stone, G. N. ; Schönrogge, K.: Parasitoids reared from galls of Andricus caliciformis, A. conglomeratus, A. coriarius, A. coronatus and A. lignicolus in Hungary (Hymenoptera: Cynipidae)

which induces bud galls on Quercus petraea, Q. pubescens, Q. robur, Q. farnetto; also on Q. virgiliana (IONESCU 1973); Q. dalechampii and Q. hartwissiana (VASSILEVA-SAMNALIEVA 1985); Q. pyrenaica, Q. faginea, Q. canadensis; also Q. macranthera and Q. iberica (MAISURADZE 1962); Q. lusitanica (DALLA TORRE & KIEFFER 1910). Andricus coronatus (GlRAUD, 1859), distributed throughout Central Europe, Balkan Peninsula, Italy, produces only asexual generation during its annual lifecycle which induces bud galls on Quercus petraea, Q. pubescens, Q. robur and Q. farnetto. VASSILEVA-SAMNALIEVA (1985) recorded this species from Q. cerris but this record must be confirmed. Andricus lignicolus (HARTIG, 1840), distributed throughout Europe and Asia Minor, produces two generations during its annual lifecycle. The asexual generation develops in summer-autumn in buds of Quercus petraea, Q. pubescens, Q. robur, Q. cerris, Q. hartwissiana, Q. farnetto, Q. pyrenaica, Q. faginea, Q. canadensis and Q. fruticosa. The sexual generation, described as Andricus lignicolus var. vanheurni by DOCTERS VAN LEEUWEN & DEKHUUZEN-MAASLAND (1958), develops in spring in buds of Quercus cerris only. Later, PATRICIA WALKER (Imperial College at Silkwood Park, United Kingdom - pers. comm.) experimentally obtained the sexual generation of A. lignicolus on Q. cerris in Great Britain. The authors recorded the sexual generation of this cynipid species in Hungary as well. Today, A. lignicolus is widespread and often the most abundant cynipid species at locations where it is present. Below we list the parasitoid species associated with the galls of the five above mentioned cynipid species complemented with the countries from where they were recorded, and the localities, if the records come from Hungary. As for the records from Hungary, the total number of reared parasitoids is given, followed by the number of males and females in brackets; then followed with sex ratio (males: females). Literature data are also included. Host relationships found by the authors are abbreviated as (A). Parasitoid complexes of the five studied Andricus species are summarized in the Table 1. Table 1.
