The effect of five different constant temperatures (18, 21, 24, 27, and 30±1°C) and a photoperiod of 14 : 10 (L : D) h on the reproduction parameters of Spodoptera frugiperda was studied. The longevity of adult female S. frugiperda decreased with increasing temperature (22.4 days at 21°C and 13.9 days at 30°C) but not at 18°C. The pre-oviposition period and oviposition period was the shortest at 30°C compared to the other temperatures. The total fecundity egg count was 887.4, 1,246.4, 1,348.9, 1,154.9, and 1,034.2 at 18, 21, 24, 27 and 30°C, respectively, during its life span. The survival rate of female S. frugiperda decreased rapidly after 13 days at 18°C, after 14 days at 21°C, after 15 days at 27°C, and after 9 days at 24°C, and 30°C. On the third day after the start of oviposition, 50% of the total fecundity was accomplished. In corn fields at less than the 10-leaf stage, the distribution of S. frugiperda egg masses was observed in the middle and lower plant regions, corresponding to 46.8% and 41.4% of the total egg masses, respectively. Egg masses were mostly found on the underside of the leaf blade (abaxial) of corn (66.7%). After releasing S. frugiperda adults on May 12, May 17, May 25, and May 30, the number of eggs per egg mass was 89.9, 88.5, 126.6, and 127.9, respectively. Egg masses of the subsequent generations of S. frugiperda were observed from late June, and the number of eggs per egg mass was 155.8 in late June, 270.7 in early July, and 303.5 in mid-July.
