Lycopersicon hirsutum f. glabratum

The wild tomato, Lycopersicon hirsutum f, glabratum is covered with trichomes which contain 2-tridecanone. The level of this compound is much lower in the domesticated tomato, U esculentum. This exudate proved to be toxic to Manduca sexta (tobacco hornworm) and to Heliothis zea (121). The density of glandular trichomes, which secrete 2-tridecanone, was influenced... [Pg.320]

Some of the complex ecological interactions mediated by plant defenses are illustrated by the resistance of a wild tomato, Lycopersicon hirsutum f, glabratum C, H. Mull, accession PI 134417, to Manduca sexta (L,), the tobacco hornworm, and its effects on several predators and parasitoids of Heliothis zea (Boddie), the tomato fruitworm. [Pg.152]
