A study on the fauna of aphids’ parasitoids was carried out in the oasis ecosystems of the Ziban in the region of Biskra, Algeria. Eighteen primary parasitoids species belong to 2 subfamilies; Aphidiinae (Hymenoptera: Ichneumonoidea, Braconidae), represented by 17 species and 6 genera (Aphidius, Diaeretiella, Ephedrus, Lysiphlebus, Praon, and Binodoxys) and the subfamily Aphelininae (Hymenoptera: Chalcidoidea, Aphelinidae), represented by only one species of the genus Aphelinus was listed. The parasitoid species were collected and identified in association with 22 species of aphids infesting 29 host plant species belonging to 13 botanical families. A number of 83 tri-trophic plant-aphid-parasitoid associations were presented. The two parasitoid species, Aphidius matricariae (Hal.) and Lysiphlebus testaceipes (Cress.), were the most abundant species. The present study dealt only with primary parasitoids, while hyperparasitoids will be presented in another publication.

Zibans（Biskra，阿尔及利亚）绿洲生态系统中的蚜虫类寄生动物群及其营养联系

在阿尔及利亚比斯克拉地区的兹班的绿洲生态系统中，对蚜虫的寄生类动物进行了研究。十八个主要寄生寄生物物种属于两个亚科。蚜虫（膜翅目：Ichneumonoidea，Braconidae），由17种和6属（蚜虫，Diaeretiella，麻黄属，Lysiphlebus，Praon和Binodoxys）和亚属亚科琳娜（膜翅目：Chalcidoidea，仅由Aphelinusae代表）。 Aphelinus被列出。收集并鉴定了寄生虫物种，与22种蚜虫相关，侵染了属于13个植物科的29种寄主植物。提出了许多83种三养植物-蚜虫-拟寄生物的关联。两种寄生虫物种，蚜虫蚜（Aphidius matricariae）（Hal。）和Lysiphlebus testaceipes（水芹）是最丰富的物种。本研究仅涉及原寄生虫，而超寄生虫将在另一出版物中发表。
