This study explores the levels of insecticide resistance in <em>Aedes aegypti</em> mosquitoes to deltamethrin. A study was carried out in dengue-endemic areas of Thailand to find the situation of insecticide susceptibility status of dengue vectors. Female <em>Ae. aegypti</em> mosquitoes were collected from <em>8</em> districts in different provinces and were exposed to various discriminating concentrations of deltamethrin (1×, 5×, and 10×) using the WHO insecticide resistance intensity bioassay. All tested populations of <em>Ae. aegypti</em> were found to be resistant to the WHO discriminating concentration of deltamethrin (0.03%). Mosquito populations collected from Surat Thani (SUT), Nakhon Si Thammarat (NST) and Ayutthaya (AYU) Provinces were resistant to deltamethrin exposure up to 10× the discriminating concentration suggesting the high resistant intensity. The effect of pre-exposure to the insecticide synergist, piperonyl butoxide (PBO), was also tested at the discriminating concentration of 0.03% deltamethrin. A significant increase in susceptibility to deltamethrin and knockdown percentage was observed in all populations of mosquitoes that were pre-exposed to PBO. These findings indicate that dengue control in Thailand with deltamethrin only could be threatened by high resistance in <em>Ae. aegypti</em> populations. It is recommended that vector control strategies incorporating PBO as an effective synergist can enhance the susceptibility of mosquitoes in the presence of deltamethrin resistance.</p></div>","PeriodicalId":15094,"journal":{"name":"Journal of Asia-pacific Entomology","volume":"27 3","pages":"Article 102282"},"PeriodicalIF":1.1,"publicationDate":"2024-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141484491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
