摘　　要：在田间自然环境条件下,进行了不同性信息素产品对斜纹夜蛾和甜菜夜蛾的诱捕比较试验。结果显示,斜纹夜蛾和甜菜夜蛾诱芯产品对斜纹夜蛾和甜菜夜蛾具有良好的专一性和明显的引诱效果。试验期间斜纹夜蛾所有诱芯共诱集到8 557头,诱蛾总量所占的百分比中1号诱芯显著高于其他4种诱芯,依次为1号>4号>5号>2号>3号。1号、2号、4号、5号速效性相似,3号速效性较差。1号、4号、5号诱芯持效期均达到70 d,1号诱芯诱集数量显著高于其他4种诱芯。性价比依次为4号>5号>1号>2号>3号。甜菜夜蛾所有诱芯共诱集到12 930头,诱蛾量所占的百分比中Ⅲ号和V号诱芯显著高于其他3种诱芯,依次为Ⅲ号>V号>Ⅰ号>Ⅱ号>Ⅳ号。5种诱芯速效性相似,差异不显著。Ⅲ号和V号诱芯持效期显著高于其他3种诱芯。性价比依次为Ⅲ号>V号>Ⅰ号>Ⅱ号>Ⅳ号。Trapping effects of different sex pheromone products on Spodoptera litura and Spodoptera exigua were compared in the field under natural environmental condition.Experiment results revealed that lure products for S.litura and S.exigua had good specificity and obvious attraction effect to S.litura and S.exigua,respective-ly.A total of 8 557 head of S.litura were trapped by 5 lure products for S.litura（No.1—No.5）.The total trap-ping amount percentage of No.1 was significantly higher than that of other 4 lures,followed by lure No.4,No.5, No.2,No.3.Readily availability of No.1,No.2,No.4 and No.5 were similar and that of lure No.3 was the worse.No.1,No.4,No.5 effective duration reached 70 days while the trapping amount of No.1 significantly higher than that of the other 4 kinds of trapping lures.Descending order of performance-price ratio of lures for S. litura was No.4 〉No.5 〉No.1 〉No.2 〉No.3.A total of 12 930 head of S.exigua were trapped by 5 lures （No.Ⅰ—No.Ⅴ）.Trapping amount percentages of No.Ⅲ and No.Ⅴ were significantly higher than that of other 3 lures,and effective duration of No.Ⅲ and No.Ⅴ were significantly longer than the other 3 lures.No significant differences of readily availability were detected among the 5 lures for S.exigua.Descending order of performance-price ratio of lures for S.exigua was No.Ⅲ 〉No.Ⅴ 〉No.Ⅰ 〉No.Ⅱ 〉No.Ⅳ.
