Anopheles sacharovi, a primer malaria vector species of Turkey, have a significant public health importance. It is aimed to determine the insecticide resistance status in Anopheles sacharovi populations in the Aegean and Mediterranean regions of Turkey. A total of 1638 individuals were analysed from 15 populations. Bioassay results indicated all An. sacharovi populations were resistant to DDT, malathion, fenitrothion, bendiocarb, propoxur. Many populations have begun to have resistance against permethrin and deltamethrin. Biochemical analyses results revealed that glutathione-S-transferases and P450 monooxygenases might be responsible from the mechanisms of DDT resistance; esterases and acetylcholinesterase might be responsible for organophosphate and carbamate resistance; P450 monooxygenases and esterases might be responsible for pyrethroid resistance into populations sampled from the study area. Allele-specific primers detected L1014F and L1014S mutations that provide kdr resistance against pyrethroids and DDT. Increased acetylcholinesterase insensitivity was detected while Ace-1 G119S mutations were not detected in An. sacharovi populations by using allele-specific primers. Overall results indicate the presence of multiple resistance mechanisms in Turkish An. sacharovi field populations suggesting that populations might gain resistance against all possible insecticide in the future. Therefore, insecticide resistance management strategies are urgently needed for effective vector control implementation.

首次实施等位基因特异性引物,用于检测疟疾载体 Anopheles sacharovi 中的敲低和乙酰胆碱酯酶靶位点突变

Anopheles sacharovi 是土耳其的一种初级疟疾病媒物种,具有重要的公共卫生重要性。其目的是确定土耳其爱琴海和地中海地区按蚊种群的杀虫剂抗性状况。共分析了 15 个种群的 1638 个个体。生物测定结果表明所有 An。sacharovi 种群对 DDT、马拉硫磷、杀螟硫磷、苯菌威、残杀威具有抗性。许多人群已经开始对氯菊酯和溴氰菊酯产生抗药性。生化分析结果表明,谷胱甘肽-S-转移酶和P450单加氧酶可能与DDT耐药机制有关;酯酶和乙酰胆碱酯酶可能是造成有机磷和氨基甲酸酯抗性的原因;P450 单加氧酶和酯酶可能是对从研究区取样的种群产生拟除虫菊酯抗性的原因。等位基因特异性引物检测到 L1014F 和 L1014S 突变,这些突变提供了对拟除虫菊酯和 DDT 的 kdr 抗性。检测到乙酰胆碱酯酶不敏感性增加,而在 An 中未检测到 Ace-1 G119S 突变。sacharovi 种群使用等位基因特异性引物。总体结果表明土耳其语中存在多种抗性机制。sacharovi 野外种群表明种群在未来可能对所有可能的杀虫剂产生抗药性。因此,迫切需要有效的病媒控制实施杀虫剂抗性管理策略。等位基因特异性引物检测到 L1014F 和 L1014S 突变,这些突变提供了对拟除虫菊酯和 DDT 的 kdr 抗性。检测到乙酰胆碱酯酶不敏感性增加,而在 An 中未检测到 Ace-1 G119S 突变。sacharovi 种群使用等位基因特异性引物。总体结果表明土耳其语中存在多种抗性机制。sacharovi 野外种群表明种群在未来可能对所有可能的杀虫剂产生抗药性。因此,迫切需要有效的病媒控制实施杀虫剂抗性管理策略。等位基因特异性引物检测到 L1014F 和 L1014S 突变,这些突变提供了对拟除虫菊酯和 DDT 的 kdr 抗性。检测到乙酰胆碱酯酶不敏感性增加,而在 An 中未检测到 Ace-1 G119S 突变。sacharovi 种群使用等位基因特异性引物。总体结果表明土耳其语中存在多种抗性机制。sacharovi 野外种群表明种群在未来可能对所有可能的杀虫剂产生抗药性。因此,迫切需要有效的病媒控制实施杀虫剂抗性管理策略。总体结果表明土耳其语中存在多种抗性机制。sacharovi 野外种群表明种群在未来可能对所有可能的杀虫剂产生抗药性。因此,迫切需要有效的病媒控制实施杀虫剂抗性管理策略。总体结果表明土耳其语中存在多种抗性机制。sacharovi 野外种群表明种群在未来可能对所有可能的杀虫剂产生抗药性。因此,迫切需要有效的病媒控制实施杀虫剂抗性管理策略。
