通过室内观测和林间应用性信息素诱捕发现,皮暗斑螟雌雄性比为1:1.05,成虫羽化全天均可进行,主要集中在傍晚日落后2h内。雄蛾对人工合成的性信息素反应模式为夜间单峰型,敏感时间为凌晨0~3时。
Through indoor observation and pheromone trapping, it was found that the male-male ratio of Porphyridium cruentum was 1: 1.05. The emergence of adults could be carried out all day, mainly within 2 hours after sunset. Sexual pheromone response patterns of male moths were single-peaked at night, with a sensitivity of 0 to 3 am.
