 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Diagnostic Doses of Two Pyrethroids Currently Used for Control of Aedes aegypti L. (Diptera: Culicidae), a Vector of Dengue) ผู้เขียน:Suntorn Pimnon, ดร.วราภรณ์ จันทรจำนงค์, ผู้ช่วยศาสตราจารย์ , คณัจฉรีย์ ธานิสพงศ์, ดร.ธีรภาพ เจริญวิริยะภาพ, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractDetermining the diagnostic dose is crucial in evaluating the susceptibility of a mosquito population to certain insecticides. Presently, the diagnostic doses of only two pyrethroids (permethrin and ?-cyhalothrin) have been published for monitoring insecticide susceptibility of Aedes aegypti. Therefore, the objective of this study was to establish the diagnostic doses for two synthetic pyrethroids—bifenthrin and ?-cypermethrin—currently used in dengue vector control, using the United State Department of Agriculture (USDA) standard strain of Aedes aegypti. These diagnostic doses were subsequently used to evaluate the susceptibility status in fi eld collected specimens of Ae. aegypti. Based on the baseline susceptibility levels, all three fi eld strains demonstrated varying levels of physiological resistance to each compound. Strong resistance to bifenthrin was seen in one strain from Nong Khai resulting in 14.14% mortality whereas complete mortality (100%) was observed in the USDA standard strain when exposed to the established diagnostic doses of these two synthetic pyrethroids. These diagnostic doses could be applied for monitoring the susceptibility status in mosquito populations across Thailand. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Resistance to Synthetic Pyrethroids in Aedes aegypti (Diptera: Culicidae) in Thailand) ผู้เขียน:Patcharawan Sirisopa, คณัจฉรีย์ ธานิสพงศ์, Theeraphap Chareonviriyaphap, ดร.วราภรณ์ จันทรจำนงค์, ผู้ช่วยศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe insecticide susceptibility level of mosquito populations is one of the major factors infl uencing the success of vector control. In this study, Aedes aegypti from seven localities with a current dengue outbreak in Thailand were subjected to synthetic pyrethroid insecticide susceptibility assays. The results revealed that Ae. aegypti from all localities were strongly resistant to bifenthrin, permethrin and deltamethrin. High resistance to lambda-cyhalothrin was detected from all localities with the exception of Ae. aegypti from Bangkok and Uttaradit which demonstrated incipient resistance. However, Ae. aegypti from Bangkok, Phra Nakhon Si Ayutthaya, Sakon Nakhon and Chumphon showed incipient resistance to alpha-cypermethrin whereas Ae. aegypti collected from Uttaradit, Mukdahan and Phatthalung were susceptible. In addition, Ae. aegypti from Bangkok, Phra Nakhon Si Ayutthaya and Uttaradit demonstrated incipient resistance to cypermethrin while susceptibility of Ae. aegypti from Mukdahan, Sakon Nakhon, Phatthalung and Chumphon to cypermethrin was observed. It was concluded that fi eld-collected Ae. aegypti from all localities had developed resistance to the synthetic pyrethroids, with the majority of these being to bifenthrin, permethrin and deltamethrin. |
