Primary parasitoids (Hym., Aphidiidae) andhyperparasitoids on aphids from NorwayTROND HOFSVANG AND ELINE B. HAGVARHofsvang, T. & Hagvar, E.8. 1983. Primary parasitoids (Hym., Aphidiidae) and hyperparasitoidson aphids from Norway. Fauna norv. Ser. B. 30. 60-62.Data on 14 species of Aphidiidae (Hymenoptera), mostly collected at As, southern Norway,are given, including 9 species new to the Norwegian fauna. With 7 additional species fromliterature records, a total of 21 species of Aphidiidae are reported from Norway. Sixteen speciesfrom 3 different families of hyperparasitoids on aphids from Norway are also listed.T. Hofsvang, Agricultural Entomology, Agricultural University of Norway, N-1432 As­NLH, Norway. E.8. Hagvar, Department of Zoology, Agricultural University of Norway,N-1432 As-NLH, Norway.The information available on primary parasitoids(Aphidiidae) and on different groups of hyperparasitoidson aphids from Norway is veryscarce. During several years study of Aphidiidaeas biological control agents on aphids in glasshousessome occational collections of mummifiedaphids were made.The species of Aphidiidae that emerged frommummies, most of them collected at As, southernNorway, are given in Tab. I. Nine speciesare new to Norway. In addition, the followingspecies of Aphidiidae from Norway are reportedin the literature: Ephedrus lacertosus (Haliday,1833) in Mackauer (1968). Ephedrus persicaeFrogatt, 1904 in Mackauer (I 968). Ephedrusplagiator (Nees, 1811) in Mackauer (I968), Edland(1976), Stary (1981). Praon abjectum (Haliday,1833) in Stary (1981). Praon gallicumStary, 1971 in Stary (1981). Praon volucre (Haliday,1833) in Edland (I 976), Stary (I 981). Aphidiusrhopalosiphi De Stephani, 190 I in Stary(I 981). Aphidius uzbekistanikus Luzhetzki, 1960in Stary (I981). Monoctonus caricis (Haliday,1833) in Mackauer & Stary (1967). Trioxys auctus(Haliday, 1833) in Stary (1981). A total of 21species of Aphidiidae are now reported fromNorway, a very low number compared to 84species reported from Finland (Halme 1977).Hyperparasitoids on aphids exist within thefollowing genera: Dendrocerus (Megaspillidae);Alloxysta, Phaenoglyphis (Cynipidae) and Asaphes,Coruna, Pachyneuron (Pteromalidae). Thespecies of hyperparasitoids that emerged frommummies collected at As, are given in Tab. 2. In60an experiment where the aphi4iid E. cerasicolawas introduced to control M. persicae on Capsicumin small glasshouses at As 1982, more regularyrecords of hyperparasitoids were made bycollecting mummies once a week (Tab. 3).Literature records exist on the following aphidhyperparasitoids from Norway: Dendroce~rus aphidllm (Rondani, 1877) in Hellen (I 966),see Fergusson (1980). Dendrocerus carpenteri(Curtis, 1829) in Edland (1976). Dendrocerusdubiosus (Kieffer, 1907) in Dessart (I 972), seeFergusson (1980). Dendrocerus laevis (Ratzeburg,1852) in Fergusson (I 980). Dendroceruspunctipes (Boheman, 1832) in Dessart (1972),biology unknown. A number of Alloxysta-speciesfrom Norway is given by Hellen(1963, 1966): Alloxysta erythrothorax (Hartig,1840), Alloxysta filicornis (Cameron, 1889), Alloxystaflavicornis(Hartig, 184 I), Alloxysta forticornis(Giraud, 1860), Alloxystafuscipes (Thomson,1862), Alloxysta macrophadna (Hartig,1841), Alloxysta pedestris (Curtis, 1838) and Alloxystavictrix (Westwood, 1833). Edland (I976)has recorded AIloxysta rubriceps (Kieffer, 1902).Asaphes sllspensus (Nees, 1834) and Asaphesvulgaris Walker, 1834 are reported by Edland(1976), Compton (1981) and Hedquist (I 982).ACKNOWLEDGEMENTSWe would like to thank Dr. P. Stary for identifyingmost of the Aphidiidae and Dr. N. Fergussonfor verifying some of the Dendrocerus sp.Fauna non' Ser 8 30 60-62 Oslo 1983
