Resistance of Lycopersicon accessions, breeding lines and cultivars to the tomato pinworm, Keiferia lycopersicella (Walsingham), and the vegetable leafminer, Liriomyza sativae Blanchard, was evaluated in 5 field studies. PI 126445 and PI 127826 (L. hirsutum Humb. & Bonpl.) and PI 126449 (L. hirsutum f. glabratum Mull.) demonstrated the highest level of resistance to both insects as measured by the number of L. sativae mines and damage and larvae of K. lycopersicella. Levels of resistance to either insect in L. esculentum Mill, accessions studied appeared intermediate. PI 129230 and PI 140403 (L. esculentum) were moderately resistant to both insects in at least two tests.
Phenological stages of ‘Flora-Dade’ tomatoes are described using a nomenclature system to be used for tomato pest management. Two vegetative stages (TV1, TV2) are listed as well as 3 reproductive plant stages (TR1, TR2, and TR3). Vegetative stage TV1 describes plants 1–15–days old with 2–3 primary leaves. TV2 describes plants 6–39 days–old with 5–7 leaves. Reproductive stages (TR1 TR2, and TR3) cover plants 40–135 days–old, characterized by presence of flowers clusters, and fruit formation and ripening. Characteristics of each stage are discussed. A senescent stage (TS1) is present from 136–200 days after plant emergence.
