摘要
【目的】探明黄翅绢丝野螟Glyphodes caesalis的求偶及交配行为节律,为该虫性信息素提取鉴定、两性通讯机制和群集诱杀技术研究提供理论基础。【方法】统计黄翅绢丝野螟的雌、雄蛹性比,测定成虫在光期和暗期的羽化率,观察其求偶和交配行为;利用等比配对试验测定寄主(菠萝蜜)、成虫日龄和暗期时段对交配率、交配时长和交配次数的影响。【结果】黄翅绢丝野螟雌、雄蛹平均性比为1.06∶1,雌蛹占比显著大于雄蛹占比。黄翅绢丝野螟成虫羽化高峰期集中于光暗转换期的前、后2 h,交配仅发生于暗期,寄主(菠萝蜜)的存在对该虫交配有促进作用,有果组交配率为93.33%±2.89%,显著高于无果组(71.67%±14.43%);有果组和无果组交配日龄分别为3-5日龄和3-7日龄;有果组3日龄成虫的交配率为53.33%±11.55%,显著高于无果组(31.67%±5.77%),两组交配率随日龄增加逐渐降低。有果组交配时段主要集中在进入暗期的0-2 h,其中暗期0-0.5 h为交配高峰期,较无果组提前,交配率为36.67%±17.56%;无果组交配时段主要集中在暗期的0-3.5 h,其中暗期1.0-1.5 h为交配高峰期,交配率为16.67%±11.55%。黄翅绢丝野螟雌成虫最多交配2次,雄成虫最多交配4次,但雌、雄成虫的交配比例随交配次数增加而递减;首次交配时间越早其多次交配概率越高,首次交配发生于3日龄的雌、雄成虫分别可进行2次和4次交配,首次交配发生于5日龄后的雌、雄成虫均无多次交配行为。【结论】黄翅绢丝野螟可进行多次交配,寄主菠萝蜜对其交配有促进作用,该虫交配行为具节律性,仅在暗期发生交配,交配高峰期为3-4日龄、大多发生在暗期的0-2 h内。
【Aim】To investigate the courtship and mating behavior rhythm of the jackfruit borer,Glyphodes caesalis,so as to provide a theoretical basis for the extraction and identification of sex pheromones of this insect,the mechanism of hermaphroditic communication and the cluster trapping technology.【Methods】The sex ratio of female to male pupae of G.caesalis was counted,the adult eclosion rates of G.caesalis during the light and dark periods were determined and its courtship and mating behaviors were observed.Moreover,the effects of host(Artocarpus heterophyllus),day-old age of adults and dark period on the mating rate,mating duration and mating frequency of this insect were also determined by proportional pairing test.【Results】The average sex ratio of female to male pupae of G.caesalis was 1.06∶1,and the proportion of female pupae was significantly greater than that of male pupae.The peak of eclosion of G.caesalis adults was concentrated in the 2 h before and after the light-dark transition period.The mating of G.caesalis occurred only in the dark period and was facilitated by the presence of the host A.heterophyllus,with the mating rate of 93.33%±2.89%in the fruiting group,significantly higher than that in the fruitless group(71.67%±14.43%).The mating age of adults in the fruiting group and fruitless group ranged from 3-5-day-old and 3-7-day-old,respectively.The mating rate of the 3-day-old adults in the fruiting group was 53.33%±11.55%,which was significantly higher than that in the fruitless group(31.67%±5.77%),while the mating rate of adults in the fruiting and fruitless groups gradually decreased with the increasing of adult age.In the fruiting group,the mating period of adults was mainly concentrated between 0-2 h into the dark period,the peak of mating occurred at 0-0.5 h of the dark period,earlier than that in the fruitless group,and the mating rate was 36.67%±17.56%.However,in the fruitless group,the mating period of adults was mainly concentrated between 0-3.5 h into the dark period,the pea
