Abstract
Hourly sampling of catches in traps equipped with blacklight lamps indicated that tobacco hornworm moths. Manduca sexta (Johannson), are active all night. When the period of darkness from 8 PM to 5 AM is considered, maximum activity of males occurred between 9 and 10 PM, and a sharp rise took place then compared with activity between 8 and 9 PM. After 10 PM, a steady decline began and continued throughout the night. The activity of females was similar to that of males, except for the relatively lower level of male activity between 8 and 9 PM. Many more males than females were captured at all hours; thus the decline in male activity after 10 PM was steeper than that for females. Activity of corn earworm moths. Heliothis Zea (Boddie), increased until 1 AM. A steady and rather sharp decline occurred after 1 AM.
