The results showed that, at 25℃, the moths had the most calling bouts, the most mating bouts, the highest calling percentage, the highest mating percentage, the shortest onset time of calling, the longest calling duration time, and the longest mating duration time per bouts, which were 6.83 bouts, 1.78 bouts, 86.21%, 82.32%, 311.35 min, 65.46 min and 43.53 min, respectively. At lower or higher temperatures than 25℃, it would prevent the calling and mating behavior of female moth of A. ipsilon. Under the photoperiod of 6 h∶18 h, the moth had the most calling bouts, the most mating bouts, the highest calling percentage, the highest mating percentage, the longest onset time of calling, the longest calling duration time, and the longest mating duration time per bouts, which were 8.45 bouts, 2.42 bouts, 93.62%, 90.63%, 347.41 min, 86.83 min and 60.33 min, respectively. With the extending of photoperiods, it would prevent the calling and mating behavior of A. ipsilon. Under the relative humidity of 55%, the moths had the fewest calling bouts, the fewest mating bouts, the lowest calling percentage, the lowest mating percentage, the longest onset time of calling, the shortest calling duration time, and the shortest mating duration time per bouts, which were 4.41 bouts, 1.34 bouts, 72.65%, 70.45%, 325.78 min, 53.45 min and 31.34 min, respectively. With the increase of relative humidity, the calling and mating behaviors of A. ipsilon were promoted. With the existence of corn leaves, the moths had the most calling bouts, the most mating bouts, the highest calling percentage, the highest mating percentage, the shortest onset %K 小地老虎 求偶行为 交配行为 环境因子< %K br> %K Agrotis ipsilon (Hüfnagel) calling behavior mating behavior environmental factor %U http://www.zwbhxb.cn/ch/reader/view_abstract.aspx?file_no=20180208&flag=1
