Surveys of the populations and the parasitoids of Liriomyza sativae Blanchard on late-season tomatoes were conducted during two years in two locations of Alabama. Population trends and extent of parasitism were tabulated. Ten species of hymenopterous parasitoids from 4 families were reared from field-collected larvae. The three most prevalent parasitoids and their percent occurrence were: 1) Opius dimidiatus (Ashmead) (Braconidae), 33.3%; 2) Chrysonotomyia sp. (Eulophidae), 20.8%; and 3) Halticoptera sp. (Pteromalidae), 19.5%.
