摘　　要：调查发现，大兴安岭落叶松毛虫ＤｅｎｄｒｏｌｉｍｕｓｓｕｐｅｒａｎｓｓｉｂｉｒｉｃｕｓＴｓｃｈｅｔｖｅｒｉｋｏｖ共有５种卵寄生蜂（其中包括１个新种）。它们的总寄生率达５４．６３％（±１．７０％），在自然控制这种害虫上发挥着重要作用。同时，对５种卵寄生蜂作了较为详细的形态描述，并对一些误名作了更正。这５种卵寄生蜂为：落叶松毛虫黑卵蜂ＴｅｌｅｎｏｍｕｓｔｅｔｒａｔｏｍｕｓＴｈｏｍｓｏｎ（细蜂总科）；松毛虫卵宽缘金小蜂Ｐａｃｈｙｎｅｕｒｏｎｓｏｌｉｔａｒｉｕｍ（Ｈａｒｔｉｇ），松毛虫迈金小蜂ＭｅｓｏｐｏｌｏｂｕｓｓｕｐｅｒａｎｓｉＹａｎｇｅｔＧｕ（新种），落叶松毛虫卵跳小蜂Ｏｏｅｎｃｙｒｔｕｓｐｉｎｉｃｏｌｕｓ（Ｍａｔｓｕｍｕｒａ）和松毛虫赤眼蜂ＴｒｉｃｈｏｇｒａｍｍａｄｅｎｄｒｏｌｉｍｉＭａｔｓｕｍｕｒａ（小蜂总科）。The present paper deals with the survey and taxonomic study of egg parasitic wasps of larch caterpillar, Dendrolimus superans sibiricus Tschetv.,in Daxinganling Mis. forests. Totally 5 wasp species were reared with 54.63(± 1.70) percent of the pest eggs were parasitized by them. It was showed that the egg parasitic wasps played a very important role in reducing the pest population in the Mis. forests. The 5 species, including a new pteromalid, are as follows. 1. Proctotrupoidea 1)Telenomus tetratomus Thomson (Figs 1 - 4 ) (Scelionidae)Chalcidoidea 2)Pachyneuron solitarium (Hartig) (Pigs 5 - 8 ) (Pteromalidae)3)Mesopolobus superansi Yang et Gu, sp. nov. (Figs 9-13) (Pteromalidae)4)Ooencyrtus pinicolus (Matsumura) (Figs 14-16) (Encyrtidae)5)Trichogramma dendrolimi Matsumura (Figs 17-19) (Trichogrammatidae)Mesopolobus superansi Yang et Gu, sp. nov. (Figs 9-13)Female: 1.9-2.2mm long. Blue-green with metallic lustre; gaster with posterior margin of tergite 1 to end purple-brown; antenna and legs having all segments except coxae stain-yellow with slight brown; wings hyaline.Head and thorax densely raised-reticulate. Head without occipital carina,the broadth 2.2 times as its length in dorsal view, 1.25 times as its height in facial view, and wider than thorax and gaster (50:42:46); POL 1.8 times as long as OOL; lateral ocellus separated from eye margin by 2.3 times its oblong diameter ; toruli ovate in shape,separated from each other only by 1/2of their own width; clypeal margin slightly excised, about 0.23 times of the head width; scrobes shallow. Antenna (Fig 10) 13-segmented with 3 anelli.Thorax wide and flat; pronotum with collar in middle part of anterior margine carinate; notauli not deep, but reaching 3/5 length of the mesoscutum;length of mesoscutum only 0.6 times of its width: scutellum longer than wide (26:22), and as long as mesoscutum. Propodeum (Fig. 13) with plicae and without median carina, in its median area having weak keels growing from anterior margin and extending posteric-laterally, and in its late
