Populations of Choristoneura rosaceana (Harris) from orchards in Ontario were shown to be resistant to azinphos-methyl and to other types of organophosphorus insecticides. Resistance extended to methyl carbamates and to methomyl. The laboratory population used for these assays and selected with azinphosmethyl was also resistant to the pyrethroid, cypermethrin. Resistance was associated with increased esterase activity and was reduced by the addition of the synergist DEF. IEF studies of esterases also indicated increased activity in resistant populations, but did not identify any unique esterases associated with the resistance. Resistance was highly correlated (r = 0.78) with elevated esterases but not with increased glutathione-S transferase activity (r = 0.13). Other mechanisms did not appear to be related.
安大略省果园中的蔷薇卷叶蛾（Harris）种群被证明对谷硫磷和其他类型的有机磷杀虫剂具有抗性。这种抗性还扩展到了氨基甲酸甲酯类和灭多威。用于这些试验并经谷硫磷筛选的实验室种群对拟除虫菊酯氯氰菊酯也具有抗性。抗性与酯酶活性增加有关，并且通过添加增效剂DEF可降低抗性。酯酶的等电聚焦研究也表明抗性种群中的活性增加，但未鉴定出与抗性相关的任何独特酯酶。抗性与酯酶升高高度相关（r = 0.78），但与谷胱甘肽 - S转移酶活性增加无关（r = 0.13）。其他机制似乎没有关联。
