樟巢螟成虫的求偶及交配行为

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.

Calling and mating behaviors of adult Orthaga achatina(Lepidoptera: Pyralidae)

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 5~(th) hour and reached the peak at the 6~(th)-7~(th) 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 5~(th)-9~(th) hour of scotophase,with the peak at the 6~(th)-7~(th) 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♂.
