Analysis of sampling procedures for corn earworm and fall armyworm (Lepidoptera: Noctuidae) in peanuts
Environmental Entomology 13 (1), 75-78
Abstract: Relative-density estimates from two insect-sampling devices (sweep-net and shake cloth) were compared with absolute-density estimates for three size classes of the corn earworm, Heliothis zea (Boddie) (Lepidoptera: Noctuidae), and the fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), in peanuts. Linear regression analysis indicated that medium and large larvae of corn earworm and all size classes of fall armyworm were consistently recovered by both devices (r2 > 0.80). Small corn earworm estimates were poor for both devices (r2 < 0.38).
