Abstract: Nipaecoccus vastator (Maskell) [=Nipaecoccus viridis (Newstead)] is an important pest infesting citrus and other fruit trees and ornamental garden plants. This study investigated the parasitic wasp resources of N. vastator in Fujian, China. The parasitic wasp species of the mealybug in the world were reorganized to include the primary parasitoids with 8 genera and 25 species of Encyrtidae, the first hyperparasitoids with 4 genera and 13 species of Encyrtidae and 1 genus and 1 species of Aphelinidae, and the second hyperparasitoids with 1 genus and 1 species of both Eulophidae and Signiphoridae. Moreover, the parasitic wasp population and the food chain relationship between the parasitoids and the mealybug were analyzed, and the first and the second hyperparasitoids were identified for the first time. At the same time, the known 8 species of parasitoids associated with N. vastator from China were clarified, a key to these parasitoid species was provided, and the morphological characteristics of the main parasitoid species were described with photos, including 1 newly recorded species for China, Anagyrus mirzai Agarwal et Alam.

Key words: Nipaecoccus vastator, parasitoids, indentification
