Abstract:The hyacinth bean plant, Dolichos lablab L., proved to be an excellent host for biological and ecological studies with Heliothis zea (Boddie) and H. virescens (F.). Flowering D. lablab did not compete with silking sweet corn in attractiveness to H. zea; however, when the corn was no longer attractive, H. zea readily established and remained along with H. virescens on D. lablab until the 1st frost. D. lablab yielded overwintering pupal populations of 7300 H. zea and 3500 H. virescens/acre, which resulted in a spring adult emergence of 3100 H. zea and 900 H. virescens/acre. H virescens initiated emergence ca. 2.5 wk before the 1st H. zea (Apr. 14, 1972); however, emergence by both species was completed within the 1st wk of May 1972.
