| 为探究酿酒高粱种子丸粒化包衣后对主要害虫的防治效果，本研究通过室内和田间试验，对比分析了丸粒化包衣和常规拌种处理下，酿酒高粱不同生育期氯虫苯甲酰胺和噻虫嗪在植株体叶片中药剂含量、生化物质变化及对螟虫和蚜虫的防治效果。结果表明，丸粒化包衣处理在酿酒高粱生长前中期叶片中具有一定浓度药剂，但低于常规拌种处理；高粱不同生育期内药剂丸粒化包衣处理的可溶性糖和类黄酮含量均显著高于常规拌种处理；高粱孕穗期，药剂丸粒化包衣对螟虫和蚜虫的防效分别为95.89%和85.40%，与常规化学防治无显著性差异（P>0.05）；植株叶片中残留药剂及抗虫次生代谢物质协同参与是药剂丸粒化包衣对靶标害虫长效控制的主要原因。因此，种子丸粒化包衣后可长效控制酿酒高粱主要害虫，在酿酒高粱生长前中期，可减少虫害防治1~2次，甚至可不施化学农药。本研究为酿酒高粱病虫害防治和田间栽培管理提供了新思路。 |

| To evaluate the control effect of seed pelletized coating of insecticide on main pests, the contents of chlorantraniliprole and thiamethoxam in the leaves of plants, the changes of chemical composition as well as the control effect of main pests (borer and Melanaphis sacchari) during different growth stages of brewed sorghum under seed pelltized coating and conventional seed coating treanments through the laboratory test and field experiment were compared. The results showed that the concentration of pesticide content in leaves of seed pelletized coating of insecticide treatment, which was lower than that of conventional seed coating treatment during prometaphase of brewed sorghum growth. The contents of soluble sugar and flavonoid contents of seed pelletized coating treatment were significantly higher than those of conventional seed coating treatment at each stages; at booting stage, the control effects of seed pelletized coating on borer moth and Melanaphis sacchari were 95.89% and 85.40% respectively, and there was no significant difference when compared with that of the conventional chemical control treatment (P>0.05); the synergistic participation of residual pesticides and secondary metabolites in leaves were the main reason for the long-term control of target pests by seed pelletized coating treatment. Therefore, seed pelletized coating of insecticide could bring long-term control over main pests, and could reducing pesticide use by 1~2 applications or enabling chemical-free cultivation, during the early and middle growth stages of brewed sorghum. This study will provide new insight for pest control and field cultivation management in the production of brewed sorghum. |
