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。
In the field of natural environmental conditions, conducted different sex pheromone products of Spodoptera litura and beet armyworm comparative experiment. The results showed that the lures of Spodoptera litura and Spodoptera exigua had good specificity and obvious lure to Spodoptera litura and Spodoptera exigua. During the experiment, all the lures induced by Spodoptera litura were 8 557, and the percentage of the total number of lures in the lure was significantly higher than that of the other four entrails, which were 1> 4> 5> 2 Number> 3. No. 1, No. 2, No. 4 and No. 5 are similar in quickness, while No. 3 is less effective. The number of induced traps of No. 1, No. 4 and No. 5 reached 70 days, and the number of trapping No. 1 was significantly higher than that of the other four kinds of traps. Value for money is 4> 5> 1> 2> 3. Beet armyworm all induced lure of a total of 12 930 head, the percentage of the amount of induced moths Ⅲ and V induced core was significantly higher than the other three kinds of induced livers, followed by Ⅲ> V> I> Ⅱ Number> IV number. The five kinds of inducers have similar quick-acting effects, with no significant difference. Ⅲ and V induced persistence was significantly higher than the other three kinds of induced. Cost-effective in order of No. Ⅲ> V> I> II> IV.
