摘　　要：为准确掌握草地贪夜蛾(Spodopterafrugiperda)在云南昭通区域的田间发生动态,将依科蔓牌和百乐宝牌2种性诱剂于2021年3—8月期间在昭通市永善、彝良、昭阳等5个县(区)进行草地贪夜蛾诱捕试验,以筛选对草地贪夜蛾诱捕效果较好的性诱剂.结果表明,2种性诱剂均可用于草地贪夜蛾监测,依科蔓牌性诱剂总诱蛾量276头,百乐宝蔓牌性诱剂总诱蛾量162头,说明试验区草地贪夜蛾发生总体较轻;4个监测点成虫首次出现在依科蔓牌性诱剂诱捕器中,3—8月虫量发生趋势和峰值两者较相似,成虫始见期和高峰期基本吻合,但依科蔓牌性诱剂在各监测点的峰期表现较百乐宝牌性诱剂稳定,诱虫专一性较好,使用成本低于百乐宝牌性诱剂,建议首选依科蔓牌性诱剂诱捕草地贪夜蛾.In order to accurately grasp the field dynamics of Spodoptera frugiperda in the Zhaotong area of Yunnan,two sexual attractants,Yikeman brand and Bailebaoman brand,were used to conduct trapping experiments on Spodoptera frugiperda in five counties(districts)including Yongshan,Yiliang,and Zhaoyang in Zhaotong City from March to August 2021 to screen for sexual attractants with better trapping effects on Spodoptera frugiperda.The results showed that both types of sexual attractants could be used for monitoring the armyworm in the grassland.The total number of moths attracted by Yikeman brand sexual attractant was 276,and the total number of moths attracted by Bailebaoman brand sexual attractant was 162,indicating that the overall occurrence of armyworm in the experimental area was relatively mild.The first appearance of adults was observed in the Yikeman sex attractant in four monitoring sites.The trend and peak of insect numbers were similar between two attractants from March to August.The initial and peak periods of adults were basically consistent,but the Yikeman sex attractant performed more stable during the peak period than the Bailebaoman sex attractant at each monitoring point,and with better specificity and lower usage cost than the Bailebao sex attractant.Therefore,it is recommended Yikeman sex attractant as the first choice for monitoring Spodoptera frugiperda in this area.
