Abstract
A survey was conducted from July 2000 to December 2001 to generate information on serpentine leafminer flies belonging to the family Agromyzidae, their host plants, and indigenous parasitoids in selected municipalities of the Cordillera. Leaf samples of vegetable crops, ornamental plants and weeds infested with serpentine leafminers were collected from the fields and kept in the laboratory for emergence of leafminer parasitoids. The specialists identified the leafminer species both by conventional method and with the use of modern molecular taxonomic tools, while parasitoids were identified using conventional taxonomic keys. A total of 39 municipalities from six Cordillera provinces, including Baguio City, were surveyed. A total of 26 vegetable crops and 19 ornamental plants and weeds that were infested by leafminers were identified. Five leafminer species were identified; four species belong to genus Liriomyza and one to genus Chrotomyia. They were: L. huidobresis (Blanchard), L. trifoli (Burgess), L. sativae Blanchard, L. chinensis (Kato), and C. horticola. The indigenous parasitoids identified were: Asecodes delucchii (Boucek), Digluphus isaea (Walker), Hemiptarsenus varicornis (Girault), Neochrysocharis formosa (Westwood), N. okasakii Kamijo, Pniglio katonis (ISHII, Quadrastichus liriomyzae Hanson & La Salle, Opius sp. and Zagrammosoma sp.
