观赏植物的质量与其植物检疫状况密切相关，而植物检疫状况又受到某些昆虫类群活动的影响。蚜虫是几乎所有植物的常见害虫，观赏植物也是其中之一。与定殖于观赏植物的蚜虫相关的区系包括建立互惠关系的蜜蚁（Hyplutera：蚁科）和有助于控制蚜虫种群的一些寄生性天敌（Hyplutera：茧蜂科，蚜虫亚科）。对生活在阿根廷科尔多瓦观赏植物上的蚜虫及其相关动物区系知之甚少。这项工作的目标是确定蚜虫殖民观赏植物，以及它们的相关蜜蚁和寄生蜂。从2003年10月至2004年11月，每周收集科尔多瓦市植物园的蚜虫定植的观赏植物的芽、叶和/或花的样品。无论何时发现，相关的蜜蚁和蚜虫的“木乃伊”攻击的寄生蜂也被收集。132个蚜虫-植物协会已登记，其中64.4%在该国不为人知。在这些协会的33.3%，蚜虫往往是蜜蚁，而蚜虫寄生蜂的存在登记在16.7%。在95种观赏植物中，蚜虫占41种，蚂蚁占6种，蚜虫占10种。蚜虫寄生蜂有4种，与11种蚜虫有亲缘关系。
The quality of the ornamental plants is closely related to their phytosanitary state, that, in turn, is affected by the activity of some insect groups. Aphids are common pests of nearly all kinds of plants, ornamental plants among them. The fauna associated with aphids that colonize ornamental plants includes honey ants (Hymenoptera: Formicidae) that establish mutualistic relations, and some parasitoids (Hymenoptera: Braconidae, Aphidiinae) that contribute to the control of the aphid population. Very little is known about the aphids and their associated fauna living on ornamental plants of Cordoba, Argentina. The goal of this work was to identify the aphids that colonize ornamental plants, as well as their associated honey ants and parasitoids. Samples of sprouts, leaves and/or flowers of aphid-colonized ornamental plants of the Jardín Botánico Municipal of Cordoba city were collected weekly, from October 2003 to November 2004. Whenever found, the associated honey ants and "mummies" of aphids attacked by parasitoids were also collected. One hundred and thirty two aphid-plant associations were registered, 64.4% of which were unknown in the country. In 33.3% of these associations, the aphids were tended by honey ants whereas the presence of aphid parasitoids was registered in 16.7%. Ninety five species of ornamental plants were colonized by 41 aphid species, whereas six ant species tended 10 aphid species. Aphid parasitoids were represented by four species related to 11 aphid species.
