摘　　要：【目的】白星花金龟Protaetia brevitarsis是重要农林业害虫,明确其交配节律,可为白星花金龟的监测、预测预报和有效防治提供科学依据。【方法】本研究在温度(23±1)℃、相对湿度60%±5%、光周期14L∶10D的环境条件下,观察不同日龄白星花金龟成虫的交配行为。【结果】白星花金龟交配行为分求偶、抱对、交尾和交配后保护四个阶段。1-5日龄段白星花金龟成虫没有求偶行为,10日龄以上的成虫有求偶、交尾现象,30-35日龄段为交配高峰。其中10-15日龄段成虫的求偶频率显著低于20-25、30-35和40-45日龄段。10-15日龄段和20-25日龄段成虫的交尾频率显著低于30-35日龄段和40-45日龄段成虫。成虫交配时间主要在11:00-14:00,夜间无交配行为。交配持续1-12 min,平均7.47 min,53.85%的成虫交配持续6-9 min。【结论】白星花金龟成虫交配行为有明显的昼夜节律性,补充营养对交配行为没有明显影响。[Objectives]To investigate the mating rhythm of Protaetia brevitarsis,an important agricultural and forestry pest,in order to improve the monitoring,prediction and control of this species.[Methods]Mating behaviors of P.brevitarsis adults of different ages were observed at(23±1)℃,60%±5%relative humidity,under a 14L:10D photoperiod.[Results]The mating behavior of P.brevitarsis can be divided into four stages;courtship,mounting,copulation and post-copulatory guarding.No courtship behavior was observed in 1-5 day-old adults.Courtship and copulation occurred in adults over 10 days of age,and peaked in those 30-35 days of age.Significantly fewer 10-15-day-old adults engaged in courtship than those aged 20-25,30-35,or 40-45 day-old.The mating rate of 30-35 and 40-45 day-old adults was significantly higher than that of those 10-15 and 20-25 days old.Moreover,mating mostly occurred from 11:00-14:00;no mating behavior was observed at night.The duration of copulation ranged from 1 to 12 min,with an average of 7.47 min.53.85%of observed copulation lasted for 6-9 min.[Conclusion]The results indicate that the mating behavior of P.brevitarsis adults has an obvious circadian rhythm,and that supplemental feeding has no significant effect on mating success.
