Silks of popcorn, zea mays L., in the Eldredge collection were evaluated for effects on growth of larvae of the corn earworm, Helicoverpa zea (Boddie), and assayed for content of maysin, chlorogenic acid, apimaysin, and 3'-methoxymaysin. The weights of 9-d-old larvae ranged from 8 mg on "PI340856" to 952 mg on "PI340855". Silks from about one-third of the popcorn collection produced corn earworm larvae equal to or smaller than larvae that fed on silks of the resistant standard, "Zapalote Chico". Content of maysin, a luteolin-C-glycoside, ranged from zero for eighteen PIs to 1.128% for "PI340856". Significant negative correlations were found
