水稻二化螟的交配行为

作者：焦晓国宣维健盛承发中国科学院动物研究所

在室内条件下,对水稻二化螟Chilosuppressalis的交配行为及能力进行了研究。结果表明:大多数二化螟雌蛾一生只交配一次,平均0.92次;而雄蛾具有多次交配能力,最多达4次,平均2.72次。二化螟雌蛾的日龄影响其交配率、交配起始时间和持续时... 详细信息

在室内条件下,对水稻二化螟Chilosuppressalis的交配行为及能力进行了研究。结果表明:大多数二化螟雌蛾一生只交配一次,平均0.92次;而雄蛾具有多次交配能力,最多达4次,平均2.72次。二化螟雌蛾的日龄影响其交配率、交配起始时间和持续时间,随二化螟雌蛾日龄的增加,其交配率逐渐下降,交配起始时间逐渐提前,而交配持续时间逐渐上升。相反,二化螟雄蛾日龄对其交配率、交配起始时间和持续时间没有明显影响。交配日龄对二化螟雌蛾的生殖力也存在显著影响,随着二化螟雌蛾交配日龄的增加,雌蛾产卵量下降,卵孵化率降低,产卵期缩短,它们都与雌蛾交配日龄存在显著的负相关;而雌蛾产卵前期和雌蛾寿命随雌蛾交配日龄的增加而延长,与雌蛾交配日龄存在显著的正相关。但二化螟雄蛾交配日龄对雌蛾的生殖力没有明显影响,二化螟雄蛾一生都具有较强的交配繁殖能力。同时,不同交配史的雄蛾与雌蛾交配,对雌蛾的生殖力也没有显著影响。表明二化螟的交配活动是由雌蛾主导控制的。最后,对这些结果在二化螟性信息素防治中应用的可行性进行了探讨。在应用性信息素控制二化螟的实践中,可以在两方面取得实效,一是性信息素可以阻碍雌雄之间正常交配,降低交配率;二是可以推迟二化螟雌虫的交配,使其产卵量和卵孵化率降低。
