The citrus leafminer, Phyllocnistis citrella (Gracillariidae), is among the main pests of citrus in Brazil. The objective of this work was to conduct a survey of parasitoids attacking CLM in Jaguariúna, State of São Paulo, Brazil, before and after the introduction of Ageniaspis citricola (Encyrtidae). Collections of new leaves were made weekly at citrus groves from July-1997 to April-1999. During the survey period, A. citricola was introduced in the area. Before this introduction, Galeopsomyia fausta (Eulophidae) was the predominant species (about 91.83% of the species composition), but A. citricola became predominant after its establishment (60.10% against 38.30% G. fausta). Other parasitoids found were Cirrospilus sp. C (Eulophidae), Horismenus sp. (Eulophidae), Elasmus sp. (Elasmidae), Eupelmus sp. (Eupelmidae) and Conura (Ceratosmicra) sp. (Chalcididae).
