Thermal requirements for development of life stages in the rednecked peanutworm, Stegasta bosqueella (Chambers), were determined. Embryonic, larval, and pupal threshold temperatures were 11.7°C (53°F), 11.0°C (52°F), and 12.2°C (54°F), respectively. Mean C° day accumulations required for completion of life stages were: 66.5 — egg, 156.0 — larva (to prepupa), 25.1 — prepupa, and 94.2 — pupa.
