为明确梨小食心虫成虫在性诱剂诱芯引诱下的成虫交配时辰节律,每个诱捕器设1,3,5,7,9,11枚性诱芯6个处理,在桃园对第2代梨小食心虫进行了试验.结果表明,梨小食心虫成虫交配的时间开始于17:00后,且活动高峰期为19:00-20:00,20:00以后活动行为明显下降；3～ 11枚性诱芯监测都能反映梨小食心虫成虫的交配时辰节律,而1枚性诱芯诱捕量与其他性诱芯诱捕量相比,差异明显.%In order to articulate mating timing rhythm of oriental fruit moth (OFM) trapped by sex pheromone, six treatments consisting of 1, 3, 5, 7, 9, 11 lure respectively in each trap and the tests were conducted in a peach orchard. The results showed that mating time of OFM started after 17:00, the peak of mating time was between 19:00-20:00 and mating behaviors obviously declined after 20:00. The treatments including 3-11 sex pheromone lures could reflect mating methods of OFM, whereas the treatment of 1 sex pheromone lure had significant difference from other treatments on trapping amounts.
