Revelation of Platygaster robiniae Buhl Duso, 2007 (Hymenoptera: Platygastridae) in the South of the Russian Far East

摘要

In the south of the Far East of Russia, the egg-larval endoparasitoid Platygasterrobiniae of the phytophage insect Obolodiplosis robiniae was found for the first time. The development of Platygasterrobiniae occurs in galls of Obolodiplosis robiniae, the host plant of which is Robiniapseudoacacia, cultivated in the arboretum of the Mountain-Taiga Station of the Branch of the Federal Scientific Center for Biodiversity of the Terrestrial Biota of East Asia, Far Eastern Branch, Russian Academy of Sciences. Despite the fact that, at present, damage to the leaves of Obolodiplosis robiniea leads to a slight decrease in the decorativeness of plants, the further spread of this phytophage can increase its damage; therefore, the detected Platygaster robiniae can be used for the biocontrol of Obolodiplosis robiniea. Further monitoring of stands of Robiniapseudoacacia in Primorsky krai is required to determine the infestation of Platygaster robiniae.
