摘　　要：为明确不同浓度40%溴酰·噻虫嗪SC对苹果绵蚜的田间防效及苹果品质的影响,2018年在云南昭阳区苹果主产区果园,采用以清水灌根为对照,40%溴酰·噻虫嗪SC 500倍液、750倍液、1000倍液在落花期至幼果形成期灌根处理进行防控苹果绵蚜效果评价。结果表明,3个浓度的40%溴酰·噻虫嗪SC溶液均可持续降低苹果绵蚜虫落数,增加虫口减退率,对苹果绵蚜均有较好较长的防效,其中750倍液40%溴酰·噻虫嗪SC对绵蚜防效最好,500倍液和1000倍液的防效次之;品质分析表明,40%溴酰·噻虫嗪SC处理可增加苹果可溶性固形物和可溶性蛋白含量,而可溶性糖、可滴定酸和维生素C含量显著降低。从降低农药施用量及保证苹果品质出发,生产中建议以750倍液、1000倍液40%溴酰·噻虫嗪SC防治苹果绵蚜为佳。The purpose of this study is to explore the effects of different concentrations of 40% cyantraniliprole and thiamethoxam SC on the field control and apple quality for Eriosoma lanigerum Hausmann. 40% cyantraniliprole and thiamethoxam SC in 500, 750, 1000 times were applied in the soil for controlling apple aphids from falling flowers to young fruit formation, water treatment as the control in the apple orchards of Zhaoyang in 2018. The three concentrations of cyantraniliprole and thiamethoxam solution reduced the number of apple aphids and increased the rate of insect pest decrease, and had a better control effect on apple aphid. Among them, 40% cyantraniliprole and thiamethoxam SC in 750 times had the best control effect on aphids, followed by 500 times and 1000 times. Quality analysis showed that 40% cyantraniliprole and thiamethoxam SC could increase the content of soluble solids and soluble protein in apples, while the content of soluble sugar, titratable acidity and vitamin C decreased significantly. In order to reduce the application of pesticides and ensure the quality of apples, our results suggest that in 750 times and 1000 times of 40% cyantraniliprole and thiamethoxam SC can be widely used to control the apple aphid.
