中文摘要:
      基于闪讯TELEMO?害虫远程实时监测系统的监测数据,分析了云南省草地贪夜蛾成虫秋冬季活动特征(种群动态、活动日节律)及与田间温湿度的相关性。结果表明:4个监测点都属于草地贪夜蛾的常年发生危害区,2019月8月1日-12月31日在各监测点均诱集到草地贪夜蛾,诱蛾量差异较大,总诱蛾量为滇南>滇中>滇东北>滇西南。在滇南、滇中冬玉米种植区诱蛾量高,日均诱蛾量分别为9.42头、8.54头,高峰期出现在8月17日和9月19日,诱蛾量85头、146头;在滇西南冬玉米零星种植区,田间湿度大,诱蛾量低,日均诱蛾量为1.21头,高峰期出现在12月23日,诱蛾量26头;在滇东北非冬玉米种植区,诱蛾量不高,日均诱蛾量4.47头/d,高峰期出现在9月28日,诱蛾量142头;雄蛾日活动节律表现为“早晚双峰型”,18:00- 03:00和07:00-11:00,高峰期分别占总诱蛾量的60.79%和24.97%,成虫活动高峰期诱蛾量与空气的温湿度有微弱的相关性,与温度的相关系数|r|=0.14<0.3,P=0.00<0.01,与湿度度的相关系数|r|=0.07<0.3,P=0.04<0.05。研究结果为改进草地贪夜蛾的性诱剂监测方法和完善成虫诱杀方法提供了参考依据。
英文摘要:
      Based on the monitoring data of Shanxun TELEMO? remote real-time pest monitoring system in autumn and winter in Yunnan, we analyzed the Spodoptera frugiperda population dynamics, adult moth activities and the correlation relationship with the temperature and humidity. The results showed that Spodoptera frugiperda occurred all year-round in four monitoring sites, from August 1st to December 31st, 2019,, the amount of moths captured in the field was varied greatly, the total amount of moths sequence was South Yunnan > Central Yunnan > Northeast Yunnan > Southwest Yunnan. In the South and middle of Yunnan, where the winter corn planting area, the number of moths captured was highest, during the monitoring period, the average number was 9.42moth/d and 8.54 moth/d. the peak time was on August 17 and September 19, and 85 and 146 moth were captured, respectively; in the South of Yunnan, winter corn scattered planting area, the relative humidity was high in the field, the number of moths captured was low, during the monitoring period, the average number was moth/d, the peak time was on December 23, and 26 moth were captured; In the Northeast Yunnan, the adult amount attracted was higher. During the monitoring period, the average number of moths lured per day was 4.47 moth/d, the peak time was September 28, and 142 moth were captured. The daily activity rhythm of male moths was "morning and evening double peak type", the peak period of 18:00- 03:00 and 07:00-11:00 accounted for 60.79% and 24.97% of the total captured number, respectively. There was a weak correlation relationship between the amount of moths and the air temperature and humidity during the peak period of adult activity. The correlation coefficient between the amount of moths and the temperature was |r|=0.14<0.3,P=0.00<0.01, and the correlation coefficient between the amount of moths and the relative humidity was |r|=0.07<0.3,P=0.04<0.05. The present study provides a guidence for improving the monitoring methods of synthetic sex pheromone traps and the trapping and killing methods of adult moth of Spodoptera frugiperda.
