对泰国各地收集的 32 个埃及伊蚊种群和来自泰国南部的 5 个白纹伊蚊种群进行了标准的世卫组织接触生物测定，以评估对三种常用合成拟除虫菊酯：氯菊酯、溴氰菊酯和高效氯氟氰菊酯的敏感性。在伊蚊中检测到对氯菊酯的广泛生理反应。埃及伊蚊的存活率从 56.5%（泰国北部的南邦府）到只有 4%（泰国东北部的加拉信府和泰国南部的普吉岛）不等。 Ae 的全部 32 个种群。发现埃及伊蚊对氯菊酯具有初步耐药性（62.5%）或被认为具有耐药性的存活水平（37.5%）。 Ae 的四个种群。发现白纹伊蚊对溴氰菊酯具有初期耐药性（97-80% 死亡率），一种对溴氰菊酯具有初期耐药性（98% 死亡率），其他地区也存在初期耐药性（观察到 97-82% 死亡率）。相比之下，Ae 的所有种群。埃及伊蚊对推荐操作剂量的高效氯氟氰菊酯完全敏感（死亡率为 100%）。 Ae 的所有五个种群。发现白纹伊蚊对溴氰菊酯和高效氯氟氰菊酯完全敏感。合成拟除虫菊酯的明确初期或耐药性的证据要求采取适当的反应和对策，以减轻耐药性的进一步发展和蔓延。根据这些发现，我们得出结论，登革热蚊媒对合成拟除虫菊酯的常规和全面敏感性监测应该是耐药性管理政策和疾病控制活动的必要组成部分。矢量生态学杂志 36 (1): 204-212。 2011年。
Thirty-two Aedes aegypti populations collected throughout Thailand and five populations of Aedes albopictus from southern Thailand were subjected to standard WHO contact bioassays to assess susceptibility to three commonly used synthetic pyrethroids: permethrin, deltamethrin, and lambda-cyhalothrin. A wide degree of physiological response to permethrin was detected in Ae. aegypti, ranging from 56.5% survival (Lampang, northern Thailand) to only 4% (Kalasin in northeastern and Phuket in southern Thailand). All 32 populations of Ae. aegypti were found to have evidence of incipient resistance (62.5%) or levels of survival deemed resistant (37.5%) to permethrin. Four populations of Ae. albopictus were found with incipient resistance (97 - 80% mortality) and one with resistance (98% mortality) to deltamethrin, with incipient resistance (observed 97-82% mortality) in other localities. In contrast, all populations of Ae. aegypti were completely susceptible (100% mortality) to the recommended operational dosage of lambda-cyhalothrin. All five populations of Ae. albopictus were found completely susceptible to both deltamethrin and lambda-cyhalothrin. Evidence of defined incipient or resistance to synthetic pyrethroids mandates appropriate response and countermeasures to mitigate further development and spread of resistance. In light of these findings, we conclude that routine and comprehensive susceptibility monitoring of dengue mosquito vectors to synthetic pyrethroids should be a required component of resistance management policies and disease control activities.
