Two trap installations were operated during 1967 in Wilson County, North Carolina, to gather information on the flying heights of tobacco insects. In I installation, insect traps equipped with blacklight lamps were mounted at about 11-ft intervals to 99 ft above ground with the lowest trap 11 ft above ground; in a 2nd installation, traps were mounted at 5-ft intervals to 20 ft above ground with the lowest trap at ground level. Catches of tobacco hornworm Manduca sexta (Johannson), and tomato hornworm, M. quinquemaculata (Haworth), were notably larger in the ground-level trap than in higher traps, indicating that catches of trap installations using blacklight as an attractant are enhanced by operating a trap at ground level to capture moths going to the ground after being attracted to traps at higher levels. Height distribution in the traps is reported for the following 12 species: salt-marsh caterpillar, Estigmene acrea (Drury); black cutworm, Agrotis ipsilon (Hufnagel); cabbage looper, Trichoplusia ni (Hübner); armyworm, Pseudaletia unipulncta (Haworth); yellow-striped armyworm, Prodenia ornithogalli Guenee; corn carworm, Heliothis Zea (Boddie); tobacco hornworm, tomato hornwom, ground beetle, Harpalus sp.; carrion beetle, Silpha surinamensis F.; and May beetles Phyllophaga crenulata Froelich and P. lulctuosa Horn.
