Evaluation of the Monitoring Effect of Different Sexual Attractants on Spodoptera frugiperda
In order to accurately grasp the field dynamics of Spodoptera frugiperda in the Zhao-tong area of Yunnan,two sexual attractants,Yikeman brand and Bailebaoman brand,were used to conduct trapping experiments on Spodoptera frugiperda in five counties(districts)in-cluding 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,indi-cating 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 at-tractant.Therefore,it is recommended Yikeman sex attractant as the first choice for monitoring Spodoptera frugiperda in this area.
