论文摘要
艾德斯白phopictus已在摩洛哥拉巴特的阿格达尔地区新录制。这种侵入性蚊子的建立可能会通过严重的流行病来影响公共卫生，尽管其在城市和郊区地区较高的滋扰。载体控制主要基于环境管理，但可以使用化学杀虫剂在高峰期降低成人蚊子密度。但是，摩洛哥尚未研究这种蚊子对杀虫剂的敏感性水平。本文报告了为监测成人和幼虫AE的杀虫剂耐药性而进行的第一项研究结果。目前在载体控制中使用的杀虫剂的白化病。该研究是在2018年5月至6月在该国西北部拉巴特进行的。按照WHO测试程序进行了成人敏感性测试。在诊断剂量（DD）下测试了一种有机氯酸盐（DDT 4％），一种拟甲虫（Cyfluthrin 0.15％），一个有机氯酸酯，一个有机氯酸盐（ddt 4％），一种有机氯酸盐（ddt 4％），一个有机氯酸盐（ddt 4％），一个有机氯酸盐（ddt 4％），一个有机氯酸盐（ddt 4％），一个有机氯酸盐（ddt 4％），一个有机氯酸盐（ddt 4％），一个有机氯酸酯（ddt 4％），一个有机氯酸盐（ddt 4％），一个有机氯酸酯（ddt 4％），一个有机氯酸盐（ddt 4％），一个有机氯酸盐（0.15％），一个氨基甲酸酯（0.1％）和一个有机磷酸盐（Fenithrothion 1％）。 Bendiocarb的五倍DD也用于产生有关蚊子成人耐药性强度的信息。执行的敏感性生物测定结果表明，该载体易受Cyfluthrin的影响，并且对DDT，Bendiocarb和Fenithrothion具有抗药性。根据谁的标准操作方案来建立剂量 - 尔术关系并扣除LC50和LC90然后抗电阻比，对Temephos进行了幼虫生物测定。我们证明了AE的幼虫种群。这种杀虫剂仍然是明智的。这些信息可以帮助决策者计划杀虫剂耐药性管理。
Aedes albopictus has been newly recorded in Agdal district at Rabat in Morocco. The establishment of this invasive mosquito could affect the public health by causing serious epidemics despite of its high nuisance in urban and sub-urban areas. Vector control is mainly based on environmental management but chemical insecticides can be used to reduce adult mosquito densities during peak periods. However, the level of susceptibility of this mosquito to insecticides has not been studied yet in Morocco. This paper reports the results of the first study conducted to monitor the insecticide resistance of adult and larva Ae. albopictus to the insecticides currently used in the vector control. The study was carried out during May-June 2018 at Rabat from the north-west of the country. Adult susceptibility tests were performed following the WHO test procedures. One organochlorate (DDT 4%), one pyrethroids (cyfluthrin 0.15%), one carbamate (bendiocarb 0.1%) and one organophosphate (fenithrothion 1%) were tested at diagnostic doses (DD). The five-fold DD of bendiocarb were also used to yield information on the intensity of mosquito adult resistance. The results of the performed susceptibility bioassay showed that the vector is susceptible to cyfluthrin and resistant to DDT, bendiocarb and fenithrothion. Larval bioassays to temephos were conducted according to WHO standard operating protocol to establish the dose-mortality relationship and deduct the LC50 and LC90 then resistance ratios. We show that larval populations of Ae. albopictus are still sensible to this insecticide. This information could help policy-makers to plan insecticide resistance management.
