New information is presented on previously introduced aphid parasitoids using the newly arrived Russian wheat aphid (RWA), Diuraphis noxia Kurdjumov 1913 (Hemiptera: Aphididae) in South Australia including species diversity and relative abundance, population dynamics and regional differences in communities. In total, eight species of primary braconids (Hymenoptera) were identified from D. noxia: Aphidius colemani Viereck, 1912 A. platensis Brèthes 1913, A. ervi Haliday 1834 (Hymenoptera: Braconidae), A. rhopalosiphi De Stefani Perez, 1902, A. salicis Haliday, 1834, A. smithi Sharma and Subba Rao, 1959, Diaeretiella rapae (McIntosh, 1855) and Lysiphlebus testaceipes (Cresson, 1880). The predominant parasitoids of D. noxia were D. rapae, A. colemani and A. platensis which was consistent across regions. This study indicates the pre-emptive importation of biological control agents (generalist parasitoid wasps) contributed to limiting an invasive pest. Data presented provides a baseline for further research on parasitoid species to reduce D. noxia, a new pest species in Australian cereal ecosystems.

澳大利亚谷物生产系统中的拟寄生虫群落及其与敌敌对的相互作用

使用南澳大利亚州新近抵达的俄罗斯小麦蚜虫（RWA）Diuraphis noxia Kurdjumov 1913（Hemiptera：Aphididae），提供了有关先前引进的蚜虫寄生虫的新信息，包括物种多样性和相对丰度，种群动态和社区区域差异。总共8种主要的茧蜂（膜翅目）从识别D.蚜：烟蚜colemani Viereck，1912 A.螺旋藻Brèthes1913 ，A. ervi茧蜂1834（膜翅目：茧蜂），A. rhopalosiphi德Stefani的佩雷斯，1902 ，A萨利奇（Salicis）1834年的哈利代（ Haliday），史密斯·沙玛（A. smithi Sharma）和苏巴·饶（Subba Rao），1959年，油菜Diaeretiella rapae（McIntosh，1855）和Lysiphlebus睾丸纲（Cresson，1880）。的主要寄生D.蚜是D.菜青虫，A colemani和A.螺旋藻这是跨区域一致。这项研究表明，先入为主的生物防治剂（一般寄生虫黄蜂）的进口有助于限制一种侵入性有害生物。所提供的数据为进一步研究拟寄生虫物种以减少D. noxia（澳大利亚谷物生态系统中的一种新有害生物）提供了基准。
