contents Lipaphis erysimi (Hemiptera: Aphididae) is one of the main insect pests on brassicaceous crops. Aphids attack crops by sucking sap from its hosts. Densed population in the initial phase of crop growth could inhibit growing, loss in yield up to 100%. Experiments were aimed to explore and identify species of L. erysimi parasitoid in highland areas of South Sumatra, and to determine potency of the parasitoids to parasitize L. erysimi in laboratory. The highest parasitism level of L. erysimi (72.40%) was found on 200 aphids which reared on B. juncea. While, the second highest parasitism level (65.67%) was found on N. indicum.
