2022、2023年连续两年利用人工饲料混药法开展新疆玉米产区5个地州(市)的亚洲玉米螟种群5种杀虫剂的抗性监测及田间验证。结果表明，室内抗性监测发现，新疆各地区玉米螟对该5种常用杀虫剂多为敏感程度，2022年与2023年结果均发现,昌吉种群(CJ-1、CJ-2)对氯虫苯甲酰胺、四唑虫酰胺、乙多·甲氧虫产生中等水平抗性，抗性倍数(RR)由高到低依次为39.82、19.24、17.99(2022)，25.17、10.57、10.33(2023)。田间防效结果与室内抗性监测结果基本一致，5%阿维菌素32.25 mL/hm²，药后28 d防效最高，为91.86%；10%溴氰虫酰胺(倍内威)可分散油悬浮剂(SC)210 mL/hm²，药后28 d防效最低，为76.64%。

This study conducted resistance monitoring of the Asian corn borer(Ostrinia furnacalis) to five insecticides in five prefectures(cities) of Xinjiang's maize-producing regions over two consecutive years(2022 and 2023) using the artificial diet incorporation method, along with field validation. The results showed that indoor resistance monitoring indicated the most populations of the corn borer in Xinjiang remained sensitive to the five commonly used insecticides. However, the Changji population exhibited moderate resistance to chlorantraniliprole, tetraniliprole, and ethiprole·methoxyfenozide in both 2022 and 2023, with resistance ratios(RR) in descending order as follows: 39.82, 19.24, 17.99(2022) and 25.17, 10.57, 10.33(2023). Field efficacy results were largely consistent with indoor resistance monitoring: 5% abamectin applied at 32.25 mL/ha achieved the highest control efficacy of 91.86% at 28 days after application, while 10% cyantraniliprole(SC) (Baineiwei) applied at 210 mL/ha showed the lowest efficacy of 76.64% at 28 days after application.
