中文摘要:
      草地贪夜蛾是新入侵我国的迁飞性重大害虫, 为害玉米的心叶、生长点及雄穗等, 能引起严重的损伤、烂心、授粉不良等, 导致玉米减产甚至绝产。本文评价了5种杀虫剂超低容量液剂通过低容量喷雾对玉米田草地贪夜蛾的防治效果。结果表明, 在相同的原药成本下, 6%甲维·茚虫威超低容量液剂和1%甲氨基阿维菌素苯甲酸盐超低容量液剂具有优异的保叶效果和杀虫效果, 5%氯虫苯甲酰胺超低容量液剂在较低的用量下(有效用量1 g/667m2)具有良好的保叶和杀虫效果, 3%呋虫胺超低容量液剂对草地贪夜蛾幼虫基本无效, 但有一定的保叶效果。
英文摘要:
      Spodoptera frugiperda is a new invasive major pest of crops, which has migratory characteristics. The insect pest mainly damage corn leaves, growth points and tassels of corn, which can cause serious damage, rotten heart and poor pollination, etc., resulting in reduced yield and even no grain. In this paper, the low-volume application technique was used to test the control efficacy of five ultra-low volume liquid insecticides on the S. frugiperda in corn field. The results showed that at the same cost of insecticide active ingredients, emamectin benzoate·indoxacarb 6% UL and emamectin benzoate 1% UL have excellent leaf retention effect and high control efficacy against the insect larvae. Chlorantraniliprole 5% UL has good leaf retention and good control effects at lower dosages (1 g /667 m2). Dinotefuran 3% UL is basically ineffective against the larvae of Spodoptera frugiperda, but has a certain leaf-preserving effect.
