Abst r a ct. I n t his paper we present t he parasit ic Hym enopt era reared from Apr ocer os leucopoda

Takeuchi, 1939 eggs and also we give not es regarding t he different parasit oids of t his invasive saw fly.

Asecodes (Teleopt er us) er xias (Walker, 1848) was reared for t he first tim e from t he eggs of Apr ocer os leucopoda. From unident ified eggs on Ulm us m inor we also reared Anast at us bifasciat us ( Geoffroy, 1785). From pupae of A. leucop odae em erged also few specim ens of an ichneum onid wasp.

Ke y W or ds: Asecodes (Teleopt er us) er xias, egg parasit oids, Apr ocer os leucopoda, new host record.

Re zu m a t: Lucrarea se int it ulează “Parazit oizii oofagi ai speciei Apr ocer os leucopoda ( Hym enopt era: Argidae) , specie invazivă provenită din Japonia” . Î n această lucrare prezentăm him enopt erele parazit oide obținut e din ouăşi pupe de Apr ocer os leucopoda Takeuchi, 1939, de asem enea dăm not e despre diferiții parazit oizi ce at acă această specie invazivă de viespe fierăst rău. Asecodes (Teleopt er us) er xias (Walker, 1848) est e obținut pent ru prim a dată din ouă de Apr ocer os leucopoda. Din ouăle unei gazde

I n t r odu ct ion. Aproceros leucopoda Takeuchi, 1939 is a m em ber of t he Argidae, a group

of sawflies, of which t here are alm ost 900 species worldwide and 68 in Europe ( Taeger & Blank 2008) . The generally free- feeding larvae are usually m onophagous or associat ed wit h several closely related host species of angiosperm s. The Arginae, one of t he t wo European subfam ilies of Argidae, include a num ber of dest ruct ive, m ultivoltine species. The East Asian sawfly Aproceros leucopoda Takeuchi, 1939 causes out breaks in sout

h-east ern Europe and severely defoliat es elm s ( Blank et al 2010; Taeger & Blank 2008) . I n Rom ania t he biology of A. leucopoda was st udied in det ail by Cardaş et al ( 2010) .

I n t his paper we present t he known parasitoids obt ained from Aproceros leucopoda. Unt il now t he only known parasit oid of A. leucopoda was Blondelia nigripes

( Fallén, 1810) ( Dipt era: Tachinidae) ( Shim a 2006) . Asecodes (T.) erx ias (Walker, 1848)

was reared for t he first tim e by us from t he eggs of Aproceros leucopoda ( Fig. 1). From

unidentified eggs, collect ed from Ulm us sp. we reared also Anast at us bifasciat us

( Geoffroy, 1785). From pupae of A. leucopoda collect ed from forest soil we reared also a

parasit oid species belonging t o t he Fam ily I chneum onidae ( Fig. 1) . I n t his not e we will present only t he dat a obt ained from t he eggs of A. leucopoda.

Asecodes (T.) erx ias ( Walker, 1848) was recorded for t he first tim e in Rom ania,

from Uzlina - Dobrogea region by Andriescu ( 1993) . Anast at us bifasciat us was recorded

M a t e r ial a n d Me t h od. Elm leafs wit h eggs of Aproceros leucopoda were collect ed in

June and August from Dărăbani and Brodoc ( Bot oşani count y) – Rom ania. The m at erial was kept under laborat ory conditions until t he parasit oids em erged.

I n t he Palearctic region, t he egg- parasitism in Superfam ily Chalcidoidea is present in 7 fam ilies: Aphelinidae, Encyrtidae, Eulophidae Mym aridae, Pt erom alidae, Tet racam pidae and Trichogram m atidae. Few egg parasit oids are grouped under Asecodes (= Teleopt erus)

belonging t o Eulophidae, a genus wit h a worldwide dist ribution. Unt il present tim e are

described only 20 species belonging t o Asecodes, t his species are parasit oids of different

Dipt era, Lepidopt era, Coleopt era and Hym enopt era ( Noyes 2003) . We t reat here

Teleopt erus as a subgenus belonging t o Asecodes, t he forewings in Teleopt erus are

charact eristic, t he cause is t he presence of 3 row s of hairs, t wo rows connect ed wit h t he st igm a and anot her one, t he cubit al line of hairs (Fig. 1e) .
