Timing and magnitude of corn earworm,Helicoverpa zea(Boddie), emergence was measured in a corn,Zea mays(L.), field near College Station, TX. Approximately 15,500H. zeaper hectare were produced, with 85% of the moths emerging in a 10-d interval. FeedingH. zeamoths were observed to be highly attracted to honeydew exudates of egrot,Claviceps paspali(F. L. Stevens&J. G. Hall) on infected florets of dallisgrass,Paspalum dilatatum(Poir.) in an adjacent pasture. Moths began feeding on the ergot at dusk. Feeding densities increased rapidly to peak at<1 h after sunset and then declined to relatively low levels by 2 h after sunset. Dissection analyses of sampled females showed that 95% were unmated, indicating that the characteristic age of the feeding moths was ≤1 d.
