摘　　要：[目的]验证5种双酰胺类杀虫剂在大豆-玉米带状复合种植模式下的安全性。[方法]建立5种药剂在大豆、玉米等基质中的残留分析方法并对田间试验样品进行分析,对比我国已制定的最大残留限量结合长期膳食风险评估模型,对5种药剂在大豆-玉米带状复合种植田的应用进行评估。[结果]5种双酰胺类药剂在3个添加水平下,在大豆、玉米等基质中的平均回收率为77%~114%,相对标准偏差(RSD)为1%~14%。5种药剂在大豆、青豆、玉米和鲜食玉米中的方法定量限(LOQ)均为0.02 mg/kg,在大豆秸秆和玉米秸秆中均为0.05 mg/kg。田间样品检测结果表明:5种药剂在大豆、青豆、玉米和鲜食玉米中的残留均低于方法定量限(0.02 mg/kg)。在大豆秸秆和玉米秸秆中5种药剂残留量分别在<0.05~1.5、<0.05~1.2 mg/kg之间。膳食风险评估结果表明:四氯虫酰胺、四唑虫酰胺、溴虫氟苯双酰胺、溴氰虫酰胺、氯虫苯甲酰胺在大豆、玉米中的长期膳食风险(%ADI)分别为2.00%、0.67%、0.59%、9.33%、0.18%,均小于100%。5种药剂累积摄入风险危害指数HI为12.77%,同样小于100%,表明对普通人群的膳食摄入风险可以接受。[结论]5种双酰胺类药剂在大豆-玉米带状复合种植中应用安全性较高,本试验结果为双酰胺类药剂在大豆-玉米田中的安全使用及登记提供了数据支持。[Aims] The aim of this study was to verify the safety of 5 diamide insecticides in soybean-maize strip compound planting. [Methods] The analysis method of 5 insecticides in soybean and maize substrates was established and the field trial samples were analyzed. Compared with the established maximum residue limit and combined with long-term dietary risk assessment model in China, the application of 5 insecticides in soybean-maize strip compound planting field was evaluated. [Results] At 3 adding levels, the average recoveries and relative standard deviations(RSD) of 5 diamide insecticides in soybean and maize substrates were 77%-114% and 1%-14%,respectively. The limit of quantitation(LOQ) of the five insecticides in soybean, green bean, maize and fresh maize was 0.02 mg/kg, and 0.05 mg/kg in soybean straw and maize straw. The residues of 5 insecticides in soybean straw and maize straw were < 0.05-1.5 and < 0.05-1.2 mg/kg, respectively. The results of dietary assessment showed that the long-term dietary risk(% ADI) of tetrachlorantraniliprole, tetraniliprole, broflanilide, cyantraniliprole and chlorantraniliprole in soybean and maize were 2.00%, 0.67%, 0.59%, 9.33% and 0.18%, respectively, which were all less than 100%. The cumulative intake risk hazard index(HI) of the five insecticides was 12.77%, which was also less than 100%, indicating that the dietary intake risk to the general population was acceptable. [Conclusions] The application safety of 5 diamide insecticides in soybean-maize strip compound planting is relatively high. The results of this study provide data support for the safe use and registration of diamide insecticides in soybean and maize fields.
