บทคัดย่อ (EN): Dengue and chikungunya remain major public health problems in Thailand. In an effort to find effective and safe insecticides to control Aedes aegypti mosquitoes, plant-derived essential oil may serve as an alternative compound to commercially available mosquito insecticides. In this study, the efficacy of Cymbopogon citratusessential oil was investigated against Ae. aegypti from areas where their parent mosquitoes were infected with dengue and chikungunya viruses. Three field strains of Ae. aegypti from Chiang Mai, Tak and Phitsanulok were detected for dengue and chikungunya viruses by One-step qRT-PCR. Essential oil from C. citratus was extracted by hydodistillation and its chemical compositions were identified by GC-MS. This oil was tested on susceptible strain of Ae. aegypti to establish discriminating concentration against F1 progeny from field-caught Ae. aegypti. The mosquitoes from all three provinces were positive for both dengue and chikungunya viruses. Dengue infection rates in Ae. aegypti ranged from 0.74% to 2.28% with DENV 1, DENV 2 and DENV 3 serotypes, whereas chikungunya infection rates in the mosquitoes ranged from 1.97% to 4.80%. The major constituents of essential oil identified were geranial (28.77%) and neral (22.74%). Discriminating concentration of the essential oil was set at 0.814%. Using the established concentration, all three field strains of F1 female Ae. aegypti were found completely susceptible to the essential oil. The efficacy of C. citratus essential oil is possibly based on its major chemical composition. C. citratus is promising plant source for the control of Ae. aegypti in dengue and chikungunya-risk areas.
