(Diptera: Culicidae) is an important vector for many human diseases. The aim of this study was to evaluate the susceptibility level of larval and adult stages of to different groups of WHO recommended insecticides for vector control.
Larval stages of the mosquitoes were collected from their natural habitats in Rafsanjan County at Kerman Province, southeast of Iran in 2016. Insecticide susceptibility status of adult female against DDT (4%), deltamethrin (0.05%), malathion 5%, and bendiocarb (0.1%) were determined using WHO standard insecticide susceptibility test. Additional test was carried out to determine the susceptibility status of larvae of to temephos. Bioassay data were analyzed by Probit program.
adults showed resistance to all four groups of the tested insecticides according to the WHO criteria for resistance evaluation. The lethal concentrations for 50% mortality (LC) and 90% mortality (LC) of temephos against larvae were 0.18mg/l and 0.78mg/l, respectively. This finding also confirms resistance to temephos based on the WHO recommended instructions for resistance evaluation.
Resistance to all groups of the tested insecticides should be considered for future vector control investigations in the study area.
（双翅目：蚊科）是多种人类疾病的重要传播媒介。本研究的目的是评估[蚊种名称]幼虫和成虫阶段对世界卫生组织推荐用于病媒控制的不同组杀虫剂的敏感水平。
2016年，从伊朗东南部克尔曼省拉夫桑詹县的自然栖息地收集了[蚊种名称]的幼虫阶段。使用世界卫生组织标准杀虫剂敏感性试验确定成年雌性[蚊种名称]对滴滴涕（4%）、溴氰菊酯（0.05%）、马拉硫磷5%和残杀威（0.1%）的杀虫剂敏感性状况。进行了额外的试验以确定[蚊种名称]幼虫对杀螟硫磷的敏感性状况。生物测定数据通过概率程序进行分析。
根据世界卫生组织的抗性评估标准，[蚊种名称]成虫对所有四组测试杀虫剂均表现出抗性。杀螟硫磷对[蚊种名称]幼虫的半数致死浓度（LC50）和90%致死浓度（LC90）分别为0.18mg/l和0.78mg/l。这一发现也根据世界卫生组织推荐的抗性评估指南证实了对杀螟硫磷的抗性。
在研究区域未来的病媒控制调查中应考虑对所有测试杀虫剂组的抗性。
