摘要:

为筛选出高效、低毒杀虫剂以防治甜菜夜蛾,采用浸渍法测定几种杀虫剂对甜菜夜蛾的室内毒力及田间药效试验。室内测定结果表明,几种杀虫剂对甜菜夜蛾的毒力顺序为:甲氨基阿维菌素苯甲酸盐>茚虫威>氯虫苯甲酰胺,其中甲氨基阿维菌素苯甲酸盐、茚虫威对甜菜夜蛾的室内毒力较高,其LC50值分别为0.067、1.806 mg/L。田间试验结果表明,1.5%甲氨基阿维菌素苯甲酸盐乳油制剂用量分别为112.5、150.0、187.5 mL/hm 2,药后3、7、10天更正防效达85%以上;5%氯虫苯甲酰胺悬浮剂制剂用量分别为450、675、900 mL/hm 2,药后3、7、10天更正防效达80%以上;150 g/L茚虫威乳油制剂用量分别为450、525 mL/hm 2,药后7、10天更正防效达85%以上。因此,生产上可推广应用。

Abstract:

The paper aims to screen out the insecticides with high efficiency and low toxicity to control Spodoptera exigua, we determined the indoor toxicity and field efficacy of several insecticides on Spodoptera exigua by impregnation method. The results of laboratory tests showed that: the toxicity of several insecticides to Spodoptera exigua ranked as follows: emamectin-benzoate>idoxacarb>chlorfenamide; among them, emamectin-benzoate and indoxacarb had higher indoor toxicity to Spodoptera exigua, with LC50 value of 0.067, 1.806 mg/L, respectively; the results of field experiment showed that: the dosage of 1.5% emamectin-benzoate EC was 112.5, 150.0, 187.5 mL/hm 2 and the corrective control effect was more than 85% in 3, 7, 10 days after treatment; the dosage of 5% chlorfenamide suspension was 450, 675, 900 mL/hm 2 and the corrective control effect was more than 80% in 3, 7, 10 days after treatment; the dosage of 150 g/L indoxacarb EC was 450, 525 mL/hm 2 and the corrective control effect was more than 85% in 7, 10 days after treatment.

Key words: emamectin-benzoate, indoxacarb, chlorfenamide, Spodoptera exigua, indoor toxicity, field efficacy
