The results showed that during the scotophase 1 (2-day-old adult), calling start time and mating start time of S. frugiperda were significantly later than the other three treatments under the purple. In the following three scotophase, the mating peak period of purple, blue and green light sources were earlier than the dark treatment, and there was no obvious different in the ovulating rhythm. In the scotophase 1, the mating time of S. frugiperda for female adults under the three light resources was not significant. But under the condition of four consecutive scotophase the cumulative mating time of S. frugiperda female audlts under dark treatment was significantly higher than those of purple, blue and green. The first mating time of female adults under dark, blue and green light resources were mainly concentrated in scotophase 1, accounting for 50.00%, 50.00% and 63.33%, respectively, while under weak purple light the first mating time of female adults was mainly concentrated in scotophase 2 (3-day-old adults, 47.67%). The distribution of the cumulative number of mating of S. frugiperda under the dark, purple, blue and green light were the highest in one time, which was significantly higher than those of other mating times. The highest number of mating for female adults was 5, 3, 2 and 3, respectively. Between the scotophase, the mating rate of S. frugiperda under the dark treatment was not significant, but the mating rates under purple light resources, blue light resources and green light sources were significantly different. The mating rate of S. frugiperda female adults was not significant under 4 scotophase. The results indicated that different light resources interference can significantly affect the reproductive behavior of S. frugiperda. keywords:Spodoptera frugiperda  reproductive behavior  light resource  interference View Full Text  View/Add Comment  Download reader
