The fall armyworm, Spodoptera frugiperda (J. E. Smith) deviated from its reported feeding habits at St. John, Kansas, in 1964. Damage to 81 Latin-American lines of corn (Zea Mays L.) was evaluated on the basis of larval feeding in the area where the leaf-sheath joins the node. Dislodged leaves sometimes resulted. This injury was used to detect differences in the response of the lines. ‘Cuba Honduras 46-J’ and ‘Eto Amarillo’ were the least damaged of the 81 lines tested. The Antigua lines probably carry a higher degree of resistance based on their high ranking in this and other tests.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
