Stydy on species of hymenopterous parasitoids attacking mangosteen leafminer (MLM), Phyllocnistis sp. (Lepidoptera: Gracillariidae) were carried out by collecting MLM infested mangosteen leaves from various mangosteen orchards in Chantaburi and Rayong provinces during August to December 1996. MLM were reared in the laboratory in order to obtain parasitoids and evaluate percent parasitism. Ten species of parasitoids emerged from reared MLM. Eight species were known as Ageniaspis citricola Logvinoskaya, Kratoysma sp., Sympiesis stritipes (Ashmead), Elasmus sp., Cirrospilus ingenuus Gahan, Eurytoma sp., Quadrastichus sp., Citrostichus phyllocnistoides (Narayanan) and other two were unidentified. The percent parasitism of 3,993 collected MLM by all parasitoids was average about 44.89 percent. The lowest percent parasitism was about 16.33 percent in November at Rayong province and the highest was about 80.57 percent in December at Rayong province. A. citricola was the most abundant species. Its average parasitism was about 25.27 percent.
