| Abstract/Contents: | "Laboratory studies were conducted to determine premating time requirements under different light regimes, influences of duration of scotophase on incidence of mating, and changes in fertlity with age in laboratory-reared fall armyworm, Spodoptera frugiperda (J. E. Smith). Females required less time after emergence (X[mean]=11.5 h) than males (X[mean]=21.5 h) before active population when held under a 15:9 (L:D) h photoperiod. The incidence of mating increased from 0.36 to 0.92 times per 24 h period as the duration of scotophase increased from 0 to 22 h. Fertility was not constant during the life span of either male or female moths. Fertility was high throughout most of the adult life, but low (especially for males) during the first 24 h after emergence." |
