摘  要:选择几种杀虫剂进行防治核桃桃小食心虫田间药效试验。结果表明,虫酰肼对核桃桃小食心虫防效最好,3个处理防效为87.10%~93.55%,建议优先使用;硫双威防效为90.32%,但鉴于其毒性为中等毒,建议选择使用;氯虫苯甲酰胺3个处理防效为80.65%~83.87%,建议适当增加用药剂量,提高防治效果;甲氨基阿维菌素苯甲酸盐和高效氯氟氰菊酯2种常规药剂防效均不足80%,建议生产中不再使用其防治核桃桃小食心虫。Several insecticides were chosen to be used against arposina niponensis on walnut. The trial results showed that tebufenozide had the best control efficacy ranged between 87. 10% - 93.55% when used against Carposina niponensis on walnuts with three different treatments, and suggested a preference for use. Thiodicarb, with the control efficacy of 90. 32%, was recommen- ded to be an alternative use considering its medium 83.87% were obtained for chlorantraniliprole, which toxicity. The control efficacy of 80. 65% - was suggested to increase the dosage to im- prove the control efficacy. The control efficacy of neither emamectin benzoate nor lambda - cyhalo- thrin reached 80%, and they were not recommended to control Carposina niponensis on walnuts.
