在阿根廷，2009年夏季报告的登革热病例超过2.5万例，即使在以前没有登革热的省份也是如此。以敏感的洛克菲勒株为对照，分析了2007/2008年夏季采集的登革热主要媒介埃及伊蚊的7个种群对杀幼虫剂Temephos的敏感性水平。虽然在实验过程中没有观察到控制失败，但大多数致死浓度和阻力比值表明存在初期阻力。一个监测Ae.抗性的综合方案。这个国家需要埃及的杀虫剂。
In Argentina, more than 25,000 cases of dengue were reported in the summer of 2009, even in provinces where the disease was formerly absent. We analysed the susceptibility levels to the larvicide temephos in seven populations of Aedes aegypti, the primary vector of dengue, collected during summer 2007/2008, using the susceptible Rockefeller strain as a control. Although no control failures were observed during the experiment, a majority of the lethal concentration and resistance ratio values indicate an incipient resistance. An integrative program to monitor the resistance of Ae. aegypti to insecticides is needed in the country.
