Effect of Temperature on Development Rate and Survival of \u3ci\u3eNomophila Nearctica\u3c/i\u3e (Lepidoptera: Pyralidae)

Development of Nomophila nearctica was studied under six constant tempera- tures in controlled temperature cabinets. Developmental threshold temperatures for egg, larval, and prepupal-pupal stages were 8.9, 1l.5, and 9.2°C. The overall mean developmental threshold temperature for all stages was 9.9°C. Degree-day summa- tions, based on the above threshold temperatures, averaged 50, 304, and 181 DD for the egg, larval, and prepupal-pupal stages, respectively. Total heat units of 535 DD are required for development from oviposition to adult emergence. Head capsule measurements indicated six larval instars
