Temporal and spatial distribution of black and dingy cutworms in midwest field crops
Environmental Entomology 11 (5), 1019-1022
Abstract: Larval populations of the black cutworm, Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae), and the dingy cutworm, Feltia ducens Walker (Lepidoptera: Noctuidae), were sampled in field crops in Missouri during the spring of 1978 and 1979. Dingy cutworms were captured in March, April, and May, whereas black cutworms were present only in May and June. Aggregation indices indicated that both dingy and black cutworms were random (Poisson) in distribution. No significant correlations between the abundance of black cutworms and the density and cover of several weeds species were detected.
