Egg parasitoids of Australian Coreidae (Hemiptera)

Abstract

Ten microhymenopteran species are recorded as parasitoids of the eggs of coreid bugs in Australia: Chrysochalcissa olivacea Girault (Torymidae) from Amorbus biguttatus Stål and Pternistria bispina Stål; two species of Anastatus Motschulsky (Eupelmidae) from Mictis profana (F.), Amorbus alternatus Dallas, Amblypelta lutescens lutescens (Distant) and an unidentified coreid; Xenoencyrtus hemipterus (Girault) (Encyrtidae) from Amorbus obscuricornis (Westwood) and Gelonus tasmanicus (Le Guillou); Ooencyrtus caurus Huang and Noyes (Encyrtidae) from A. lutescens lutescens;Centrodora darwini (Girault) (Aphelinidae) from an unidentified coreid; and four species of Gryon Haliday (Scelionidae) from Aulacosternum nigrorubrum (Dallas), A. lutescens lutescens, Amorbus rubicundus Stål, Mictis caja Stål, M. profana and an unidentified coreid. Alternate hosts and biological control prospects are discussed.
