摘要: 在光周期14 L∶〖KG-*2〗10 D、温度(27±1) ℃、相对湿度(60±10)%的室内条件下,研究了樟巢螟成虫的求偶及交配行为.结果表明:樟巢螟雌蛾在光期不求偶,进入暗期后少数个体开始求偶,暗期5 h求偶个体百分率明显增加,暗期6~7 h达求偶高峰期;不同日龄雌蛾的求偶率不同,以2~3日龄雌蛾较高,高峰期求偶率达70%以上;樟巢螟雌雄蛾的交配行为依时间顺序可分为求偶和交配2个过程;雌雄蛾间的交配主要发生在暗期5~9 h,交配高峰期在暗期6~7 h,与雌蛾的求偶高峰期一致;樟巢螟雌蛾一生只交配1次;雌雄比1∶1处理的雌蛾交配率显著低于雌雄比1:2处理,但前者的交配持续时间明显高于后者.

Abstract: A laboratory study was made on the calling and mating behaviors of adult Orthaga achatinaat (27±1) ℃, (60±10) % RH, and 14 L:10 D photoperiod.
 The female O. achatina did not call until the start of scotophase, with the calling percentage increased sharply at the 5th hour and reached the peak
 at the 6th-7th hour of scotophase. The calling percentage varied with moth age, being the highest (>70%) at the age of 2-3 d. The mating behavior could be divided into two successive periods, i.e., calling period and mating period. The mating between female and male O. achatina occurred during the 5th-9th hour of scotophase, with the peak at the 6th-7th hour into scotophase, which was in accordance with the peak time of female calling behavior. Females mated only one time during their whole life. Treatment 1♀∶2♂showed a significantly higher mating percentage, but a significantly shorter mating duration time, compared with treatment 1♀∶1♂.
