Abstract

Oobius Trjapitzin (Hymenoptera, Encyrtidae) species are egg parasitoids that are important for the biological control of some Buprestidae and Cerambycidae (Coleoptera). Two species, O. agrili Zhang & Huang and O. longoi (Siscaro), were introduced into North America for classical biocontrol and have successfully established. Two new native North American species that parasitize eggs of Agrilus spp. (Buprestidae) are described and illustrated from the USA: O. minusculus Triapitsyn & Petrice, sp. n. (Michigan), an egg parasitoid of both A. subcinctus Gory on ash (Fraxinus spp.) and A. egenus Gory on black locust (Robinia pseudoacacia L.) trees, and O. whiteorum Triapitsyn, sp. n. (Pennsylvania), an egg parasitoid of A. anxius Gory on European white birch (Betula pendula Roth). A taxonomic key and notes on the Nearctic native and introduced Oobius species are also included.
