It discusses that when a new fungicide comes to the market, the resistance risk evaluation, resistancemonitoring and resistance management influence decisions on whether it will be worth developing and marketing.
杀菌剂抗性风险是指病原菌抗药性发展使杀菌剂防效丧失或药效降低的可能性。
2.
To evaluate risk of resistance to fungicide is of great importance in developing, introducing, applying novel fungicides, and managing resistance, however, systemic evaluation to resistance risk has not been made yet in China, examples of risk evaluation are rare abroad and prediction is often not in accordance with actual situation.
杀菌剂抗性风险评估对于新药的研制、引进、应用和抗药性治理的决策至关重要,我国对此尚未系统研究,国外评估病菌抗药性风险实例极少,预测往往与实际不符。

In order to expound the mechanism of chlorfenapyr and the resistance risk of beet armyworm (Spodoptera exigua) to chlorfenapyr, the toxicity of chlorfenapyr to beet armyworm larvae (S.
为明确虫螨腈的致毒机理及甜菜夜蛾(Spodoptera exigua)对虫螨腈的抗性风险,本文以甜菜夜蛾为试虫,采用微量点滴法测定了虫螨腈对不同龄期甜菜夜蛾幼虫的毒力以及PBO(增效醚)、DEM(顺丁烯二酸二乙酯)和TPP(磷酸三苯酯)三种增效剂对虫螨腈的增效作用;测定了虫螨腈对甜菜夜蛾幼虫呼吸作用、保护酶系(超氧化物歧化酶SOD、过氧化物酶POD、过氧化氢酶CAT)、解毒酶系(羧酸酯酶、谷胱甘肽-S-转移酶、细胞色素P450酶系)的影响;采用点滴法进行了甜菜夜蛾对虫螨腈的抗性筛选,获得了对虫螨腈低水平抗性的甜菜夜蛾品系,并比较了抗虫螨腈甜菜夜蛾种群与相对敏感种群幼虫氧化磷酸化水平、解毒酶系比活力、保护酶系比活力、生物适合度的差异;测定了虫螨腈与其他药剂间的交互抗性。
