Abstract: | Oobius Trjapitzin (Hymenoptera, Encyrtidae) species are egg parasitoids that are important for the biological control of some Buprestidae and Cerambycidae (Coleoptera). Two species, Oobius
agrili Zhang & Huang and Oobius
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: Oobius
minusculus Triapitsyn & Petrice, sp. n. (Michigan), an egg parasitoid of both Agrilus
subcinctus Gory on ash (Fraxinus spp.) and Agrilus
egenus Gory on black locust (Robinia
pseudoacacia L.) trees, and Oobius
whiteorum Triapitsyn, sp. n. (Pennsylvania), an egg parasitoid of Agrilus
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. |
