A Review of Species of the Genus Oobius Trjapitzin, 1963 (Hymenoptera, Encyrtidae) - Egg Parasitoids of Jewel Beetles, Longicorn Beetles (Coleoptera, Buprestidae, Cerambycidae), and Robber Flies (Diptera, Asilidae)

摘要

The review contains diagnosis of the genus Oobius Trjapitzin, 1963 (Hymenoptera, Encyrtidae), a key to the females of its 9 species described in the world fauna, and synopsis of the species with data on their distribution and hosts. Special attentionis paid to an economically important species, Oobius agrili Zhang et Wang, 2005, introduced from China into USA and Canada for biological control of the emerald ash borer Agrilus planipennis Fairmaire (Coleoptera, Buprestidae), a very dangerous pest of ashes (Fraxinus spp.). This buprestid has also recently penetrated into Russia, which necessitates introduction of its egg parasitoid, O. agrili. Coccidencyrtus pinicola Mercet, 1921 from Spain is transferred to the genus Oobius, hence a new combination,O. pinicola (Mercet), comb, n., is proposed. The lectotype of Tyndarichus rudnevi S. Nowicki, 1928 (type species of the genus Oobius) is designated in the collection of the National Museum of Natural Sciences in Madrid and this is formally fixated in thepresent review. The material of Oobius has been studied in depositories of St. Petersburg, Warsaw, Madrid, and Monterrey (Mexico).
