摘要 為準確掌握草地貪夜蛾成蟲發生動態，篩選對當地種群專一性強、靈敏度高的性誘劑，對深圳百樂寶生物農業科技有限公司（BLB）、寧波紐康生物技術有限公司（NK）、江蘇寧錄科技股份有限公司（NL）、南京新安中綠生物科技有限公司（XAZL）4個廠家生產的草地貪夜蛾性誘劑在江蘇鹽城市大豐區進行田間誘捕效果試驗，探討草地貪夜蛾性誘劑的使用技術。結果表明：4種不同性誘劑誘芯對草地貪夜蛾的誘集效果存在明顯差異。BLB誘芯和NL誘芯可以有效監測草地貪夜蛾成蟲田間發生動態，羽化高峰期明顯，且峰值日期一致，NK誘芯誘集的成蟲蟲峰不明顯，XAZL誘芯零星誘到成蟲，無明顯成蟲高峰;BLB誘芯監測期內日均誘蛾量、最高單次誘蛾量、總誘蛾量均顯著高于其他3種誘芯，其總誘蛾量達136.75頭，分別是NL誘芯、NK誘芯、XAZL誘芯的1.47倍、4.76倍、10.52倍;通過對BLB誘芯進行持續30 d和持續60 d的誘捕對比試驗，發現BLB誘芯1～30 d內誘捕性能穩定，誘蛾量大，31～60 d內日均誘蛾量、最高單次誘蛾量、總誘蛾量均有所下降且達顯著水平，尤其是50 d后誘捕量下降明顯。結果表明：BLB誘芯的誘蛾量大，能夠明顯反映出草地貪夜蛾的羽化高峰期，符合測報要求，更適合本地區草地貪夜蛾的監測，使用該誘芯時建議30 d更換1次。

Abstract In order to accurately monitor the occurrence dynamics of the adults of Spodoptera frugiperda， the attract effect of sex pheromone attractants produced by Shenzhen Bailebao Bio-Agricultural Technology Co.， Ltd. （BLB） and Ningbo Newcom Biotechnology Co.， Ltd. NK）， Jiangsu Ninglu Technology Co.， Ltd. （NL） and Nanjing Xinan Zhonglü Biotechnology Co.， Ltd. （XAZL） were compared in the corn field at Dafeng district of Yancheng city， Jiangsu province. The results showed that the trapping effects of the four sex attractants were significantly different. When the products of BLB and NL were used in monitoring the occurrence dynamics of S. frugiperda adult， the peak period of emergence is obvious， and the peak date monitored by the two products is consistent. While the peak date monitored by NK product is not obvious， and the XAZL product attracted very few moths， and there is no obvious adult peak. The daily average moth amount， the maximum moth amount per day and total moth amount were significantly higher than the other three products during the monitoring period. The total amount of moth attracted by the BLB lure was 136.75 individuals， which were 1.47 times， 4.76 times and 10.52 times of that the NL， NK and XAZL attractants. The trapping performance of BLB lure was stable within first 30 d. However， the daily average moth amount， the maximum moth amount per day and the total moth amount were all significantly decreased during the second 30 d， especially after 50 days. The results showed that the BLB lure is more suitable for the monitoring of S. frugiperda in this area. It is recommended to replace it every 30 days.
