Nineteen parasitoids of Cydia caryana (Fitch) were found in six pecan-growing areas of Coahuila State (Saltillo, Monclova, General Cepeda, Parras de la Fuente, Muzquiz, and Torreon). Calliephialtes grapholithae (Cresson, 1890), Phanerotoma fasciata (Provancher, 1881), Hyssopus spp. (Linnacus, 1753), and Apanteles epinotiae (Forester, 1962) were most common. Calliephialtes grapholithae parasitized 26.46% of shuckworm larvae at Saltillo and 7.04% at Parras, while P. faciata parasitized 10.05% of larvae at Saltillo and 30.99% at Parras. Parras de la Fuente was the pecan-growing area with most parasitism (53.52%), followed by Saltillo (46.93%), General Cepeda (41.38%), Monclova (24.0%), Muzquiz (17.24%), and Torreon (5.52%).
