Dalmatian and yellow toadflax, Linaria dalmatica and L. vulgaris, are exotic weeds in North America, and their classical biological control has been improved by the establishment of seed-feeding (Rhinusa antirrhini) and stem-mining (Mecinus janthinus and Mecinus janthiniformis) weevils. Here, we evaluated the complex of hymenopteran parasitoids attacking these weevils in Colorado. Ten species were identified of the genera Neocatolaccus, Eurytoma, Pteromalus, Brasema, Telenomus and Bracon. Neocatolaccus tylodermae was the most abundant parasitoid of M. janthinus, M. janthiniformis and R. antirrhini. This is the first report of N. tylodermae attacking the weevil genera Mecinus and Rhinusa feeding on the genus Linaria. [ABSTRACT FROM AUTHOR]
