The 24-h circadian rhythm is considered crucial for insect sexual communication. However, its molecular mechanisms and signaling pathways, particularly the roles of the clock gene period (Per), remain largely unclear. The sex pheromone communication behavior of Spodoptera litura displays typical circadian rhythm characteristics. Thus, it represents an excellent model for functional analyses of the clock gene Per.

RNAi介导的SlitPer沉默破坏了斜纹夜蛾的性信息素通讯行为

24 小时昼夜节律被认为对于昆虫的性交流至关重要。然而，其分子机制和信号通路，特别是时钟基因周期（Per ）的作用，目前仍不清楚。斜纹夜蛾的性信息素通讯行为表现出典型的昼夜节律特征。因此，它代表了时钟基因Per功能分析的优秀模型。
