Abstract: A two-month survey of the natural enemies of the gypsy moth, Lymantria dispar (L.),in Beijing and the northeastern People's Republic of China confirmed the presence of 22 parasitic species in the genera, Hexamermis, Exorista, Carcelia, Parasetigena, Chetogena, Blepharipa, Elachertus, Anastatus, Tyndarichus, Rogas, Meteorus, Glyptapanteles, Cotesia, Apanteles, Phobocampe, Casinaria, Hyposoter, Campoletis, Ephialtes and 12 predatory species in Araneus, Harpactor, Epidaus, Picromerus, Dinorhynchus, Pinthaeus, Xylodrepa, Carabus, and Calosoma. Species diversity was greatest at Menjiagang, Heilongjiang Province, where the host population was moderate. Populations were low in 10 other collection sites. Nuclearpolyhedrosis virus (NPV) was moderately abuudant while the fungus Entomophthora aulicae occurred in some collected larvae and was evident in year-old cadavers, especially in Larix plantations at Dunhua, Jilin province. The most abundant parasites were the tachinids (5 species combined) and the gregarious braconid, Glyptapanteles liparidis.
