| 中文摘要:为了解温度、光照周期、相对湿度及寄主植物对小地老虎求偶及交配的影响，采用直接观察法研究这些因子对小地老虎求偶及交配的影响。结果表明，温度为25℃时，小地老虎的求偶次数、交配次数最多，求偶率、交配率最高，求偶起始时间最短，求偶持续时间、单次交配持续时间最长，分别为6.83次、1.78次、86.21%、82.32%、311.35 min、65.46 min、43.53 min，高于或低于25℃会抑制求偶及交配；光照周期为6 h∶18 h时，小地老虎的求偶次数、交配次数最多，求偶率、交配率最高，求偶起始时间、求偶持续时间、单次交配持续时间最长，分别为8.45次、2.42次、93.62%、90.63%、347.41 min、86.83 min、60.33 min，光照周期延长会抑制求偶及交配；湿度为55%时，小地老虎的求偶次数、交配次数最少，求偶率、交配率最低，求偶起始时间最长，求偶持续时间、单次交配持续时间最短，分别为4.41次、1.34次、72.65%、70.45%、325.78 min、53.45 min、31.34 min，湿度升高会促进求偶及交配；放玉米叶片时，小地老虎的的求偶次数、交配次数最多，求偶率、交配率最高，求偶起始时间最短，求偶持续时间、单次交配持续时间最长，分别为8.87次、2.73次、95.32%、93.26%、262.42 min、85.52 min、64.67 min。 |

| Abstract:To understand the effects of temperature, photoperiod, relative humidity and host plants on the calling and mating behavior of female moths of black cutworm Agrotis ipsilon (Hüfnagel)，the effects of these factors on the calling and mating behavior of female moths of A. ipsilon were studied in the laboratory with direct observation method. 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 time of calling, the longest calling duration time, and the longest mating duration time per bouts, which were 8.87 bouts, 2.73 bouts, 95.32%, 93.26%, 262.42 min, 85.52 min and 64.67 min, respectively. |
