摘  要：
在2019和2020年调查了菏泽地区草地贪夜蛾的发生和为害情况。通过形态学和分子生物学方法鉴定明确了菏泽地区的草地贪夜蛾物种。利用灯诱和性诱监测成虫、田间调查监测幼虫,连续2年的数据表明,草地贪夜蛾在8月中旬左右迁飞至菏泽地区,选择低于大喇叭口期的玉米上产卵为害;成虫监测方面,性诱效果显著高于灯诱。上述结果表明,草地贪夜蛾成功入侵山东菏泽地区,虽然害虫种群密度和发生为害面积小,但有扩张的趋势,后续应在山东菏泽地区继续加强对草地贪夜蛾的监测预警。

摘  要：
The population dynamics of S.frugiperda in Heze in 2019 and 2020 were investigated.Firstly, species were determined in Heze with morphology and molecular biology method.Then, the larvae was monitored by artificial investigation in the field and the adults with light trap and sex pheromone.Our results from last two years indicated that the S.frugiperda migrated into Heze and selected corn at vegetative stages(before eleventh leaves) to lay eggs, suggesting that it's important to monitor the S.frugiperda in middle August in Heze.The number of arrested S.frugiperda adults with sex pheromone was more than the ones with light traps, suggesting that it's better with the former than the later for monitoring S.frugiperda in Heze.The disaster area of larvae increased in 2020 compared to the ones in 2019.These results suggested that S.frugiperda successfully invaded Heze in last two years and although the number of population and the disaster area was relatively low, they were increased and suggested the importance of monitoring S.frugiperda in Heze.
