Abstract
This study aimed to aware the efficacy of Deltamethrin single-acting formula and mixed-acting formula to eliminate Aedes aegypti by Thermal space spraying in the dengue fever endemic area, Bang Sai Sub-district, Mueang District, Chonburi Province. This research was an experimental research which was performed by the Cage Bio-assay test. The sample groups were 3-5 days old adult female Aedes aegypti, laboratory strain and Bang Sai strain. The test was performed with Deltamethrin single-acting formula; consisting of Deltamethrin 0.5% at a rate of 1 g/ha, and Deltamethrin mixed-acting formula; consisting of Deltamethrin 0.5% + S-bioallethrin 0.75% + Piperonyl Butoxide 10% at a rate of 0.75 g/ha. The results of the study found that the efficiency of Deltamethrin single-acting formula when tested with Aedes aegypti in the laboratory and Bang Sai found a mortality rate of 100 % for both mosquito stains, and Deltamethrin mixed-acting formula when tested with Aedes aegypti in the laboratory and Bang Sai found a mortality rate of 100 % for both mosquito species. Therefore, from the results of the study, it was found that the Deltamethrin single-acting formula with an application rate of 1 gram/ha and the Deltamethrin mixed-acting formula with an application rate of 0.75 grams/ha, these could eliminate Aedes aegypti
in the outbreak areas with no difference, with a mortality rate of both mosquito species of 100 %.
In addition, the outbreak situation in the area should study other factors for effective disease control.
