摘要：【目的】开展吐伦球坚蚧生物防治技术研究,调查该害虫的寄生性天敌昆虫。【方法】采集■■树带有吐伦球坚蚧若虫、成虫的枝条,带回室内,置于试管中饲养,以获得天敌。【结果】调查发现一种寄生该害虫的金小蜂新种——吐伦球坚蚧蚧盾金小蜂Eunotus turanicusi Yang et Kereman,详细描述该寄生蜂新种的形态特征,提供清晰的形态特征彩色照片;并记述其生物学、分布等基础信息;列出区分新种与相近种——强壮蚧盾金小蜂E.strenus Xiao et Huang的检索表。【结论】本研究为生物防治吐伦球坚蚧这种危害多种果树的重大害虫找到了一种新天敌,在生物防治上具有重要价值。
【Objective】Rhodococcus turanicus（ Archangelskaya）（ Hemiptera： Coccidae） attacks many fruit tree species in Xinjiang and Ningxia areas,including almond,apricot,peach,apple,and pear. In order to develop non-pollution control techniques to manage the severe insect pest,a biocontrol study was carried out and the insect natural enemies were for the first time investigated.【Method】Twigs of the host tree,Cydonia oblonga（ Rosaceae）,with nymph and adults of the scale pest were collected,and then put in glass tube for rearing parasitic wasps. The natural enemies were gathered for taxonomic study when they emerged. 【Result 】A new parasitoid species, Eunotus turanicusi Yang et Kereman（ Hymenoptera： Pteromalidae）,was found during the survey through taxonomic study. The morphological characteristics of the new species of the parasitoid are described in detail in this paper,and the clear morphological features and color photos are provided. The basic information of its biology and distribution is also described. Meanwhile,a key to distinguish the new species from the closed species Eunotus strenus Xiao et Huang 2001 is provided. The characters below are different from the latter species： Male antenna with scape and pedicel yellow brown,but ventral half of scape luteous,flagellum dark brown. Female antenna with funicle 2 as long as broad; malar space as long as eye height; POL 3. 5 times OOL; posterior ocelli attached occipital carina; fore wing with postmarginal vein 1. 3 times as long as stigmal vein;metasoma with seven visible tergites and 1 st tergite 0. 5 times as long as gaster.【Conclusion】The present investigation has found a new parasitoid species and provides a new natural enemy for biocontrol of the pest.
