Abstract
Effects of corn, Zea mays L., phenology and temperature on developmental time, dry weight consumption, pre-ovipositional period, longevity, fecundity, and egg viability were measured on the fall armyworm, Spodoptera frugiperda (J. E. Smith). Food consumption was 24% lower on stages 1-2 than on stages 3-4 and decreased as temperature increased from 21@* to 30@*C. Adult female longevity was shortest for stages 3-4 and declined with increasing temperature. Fecundity was greatest at 21@* and 25@* and declined at 30@*C. Pre-oviposition period (4.5 days) and egg viability (92%) were unaffected by temperature and corn stage. Developmental time was longer at constant 25@* than at a mean of 25@* which fluctuated between 20@* and 30@*C.
