摘要
为了探明白星花金龟Protaetia brevitarsis Lewis的羽化节律和羽化进程、交配行为及交配节律,在室内恒定条件下(光照周期为L∥D=14h∥10h,温度为(25±2)℃,相对湿度为75%~80%),对白星花金龟的羽化及交配行为进行了观察,结果表明:1)羽化在白天和晚上均可发生,雌雄羽化节律均表现出驼峰型,雌虫羽化最高峰出现在04:00-06:00,雄虫的羽化最高峰出现在16:00-18:00;2)羽化进程为33d,羽化高峰期为开始羽化后的15~33d,羽化数占总数的76.77%,雌虫较雄虫羽化早;3)交配行为分为相遇和交配。相遇包括相互避让、相互攻击、爬背、抱对、交配等;交配包括爬背、抱对和交配,部分具有配后保护行为;4)72h内交配不止一次的占30%,交配持续时间最短的为95s,最长的295s,平均(182±28)s;5)24h内抱对出现了两个高峰:18:00-20:00和20:00-22:00,抱对率分别为92.5%和90%,且差异不显著(P>0.05),但是和其他时间段具有显著性差异(P<0.05);6)24h内有两个交配高峰,分别为12:00-14:00和20:00-22:00,交配率分别为35%和40%,且和其他时间段呈显著差异(P<0.05)。白星花金龟在00:00-08:00和16:00-20:00时间段未发生交配现象。
In order to ascertain emergence rhythm and emergence process,mating behavior and mating rhythm of Protaetia brevitarsis Lewis,the emergence and mating behavior of this beetle were investigated under constant conditions（25℃±2℃,RH 75%-80%,L∥D=14 h∥10 h）.The results showed that the beetle could emerge in the daytime and at night.The emergence rhythm showed the hump pattern,with the female＇s emergence peak at 04：00-06：00 am and the male＇s emergence peak at 16：00-18：00 pm.The emergence lasted for 33 days,and the peak appeared from the fifteenth to thirty-third day after the beginning.The number of emerged adults at peak time accounted for 76.77% of the total.The female emerged earlier than the male.The mating behavior is divided into meeting and mating.Meeting included the avoidance,fighting,climbing on female＇s back,mounting,mating,etc.,Mating included climbing on female＇s back,mounting,mating,post-copulatory guarding behavior observed in some beetles.Mating frequency more than once within 72 haccounted for 30% of the total.The shortest mating duration was 95 seconds,the longest was 295 seconds,and the average was 182±28 seconds.There were two mounting peaks within 24 hours,with the mounting rate of 92.5% and 90% at 18：00-20：00 pm and 20：00-22：00 pm,which was not significantly different（P0.05）,but significantly different from the mounting rate at other time（P0.05）.There were two mating peaks within 24 hours,with the mating rate of 35% and 40% at 12：00-14：00 pm and 20：00-22：00 pm,respectively,significantly different from the mating rate at other time（P0.05）.Mating didn＇t occur between00：00-08：00 am and 16：00-20：00 pm.
