Determination and Consideration of Flight Potential in a Laboratory Population of True Armyworm (Lepidoptera: Noctuidae) [PDF]

Environmental Entomology, 2002
Flight potential, a poorly understood phenomenon in the migratory true armyworm, Pseudaletia unipuncta (Haworth), was investigated in a laboratory population using tethered-flight techniques. True armyworm exhibited strong flight potential relative to other known migratory noctuids whose flight potentials were previously determined by similar ...
