2、期5h开始雌雄蛾交配率明显上升,并且在暗周期6.5~7h达到交配高峰期;不同日龄成虫的交配率不同,以2~3日龄的成虫交配率较高,高峰期交配率达到43%;樟巢螟雌雄蛾的交配行为依时间顺序可以分为预交配期和成功交配期2个过程。雌雄蛾间的交配主要发生在暗周期5~9h。雌蛾产卵全程都在暗周期内,交配后第1天有少许雌蛾开始产卵,第2天产卵雌蛾开始大量增加,第3天时达产卵高峰,而第4天产卵量急剧下降,其中在第2天和第3天达到产卵总数的84%;室内条件下卵块为2~3层的层堆,每卵块平均47.6粒。雌雄蛾的交配率及雌虫产卵量和虫龄有着显著的曲线相关性。关键词:樟巢螟成虫;交配行为;产卵行为中图分类号:S
