Abstract
Pyrethroids such as deltamethrin (DEL) and bifenthrin (BT) have been widely used in prevention, control, and elimination of insect pests of durian in durian plantation areas of Borai District, Trat Province. This study assessed the susceptibility of Mansonia uniformis female adult populations collected from a horticulture area of urban fringe in Bo Phoi Subdistrict, Borai District, Trat Province as compared to Anopheles dirus collected from rubber plantation area of forest fringe in Dan Chumphol Subdistrict, Borai District, Trat Province. Insecticide susceptibility test using discriminating concentrations of 0.05% DEL and 0.09% BT as recommended by the World Health organization was done. Findings of testing the susceptibility revealed that the susceptibility of Ma. uniformis to DEL (mortality of 92.5% and 95% CI = 89.6-95.7) and BT (mortality of 88.6% and 95% CI = 83.4-93.8) had a tendency to decrease its susceptibility and hence increased resistance. Meanwhile An. dirus was highly susceptible to both DEL and BT showing the mortality of 100%. Possible resistance in Ma. uniformis requires for further testing of confirmed resistance whether the same population tested possesses pyrethroid-resistant genes.
