Abstract
Objective: This study aims to determine the susceptibility status of Aedes aegypti, Aedes albopictus, Culex quinquefasciatus and Anopheles subpictus to insecticides Cypermethrin 0.05% in Makassar City. Methods: The samples were adult females of mosquitoes aged 3-5 days. They were tested with exposure of Cypermethrin 0.05% and one control with three replication. The number of samples per test treatment and control was 20. The data were analyzed by looking at the mortality percentage of each treatment to determine differences in susceptibility status to Cypermethrin 0.05%. The analysis also involved a probit test on a Minitab application to view the LT50, LT90, LT95, LT99. Results: Showed that the mortality rate of Aedes aegypti was 53.3% with a resistant status, while the result for Aedes albopictus and Culex quinquefasciatus were 85% and 81.7% respectively with a tolerant status. Anopheles subpictus was still susceptible with a mortality rate of 100%. The LT99 values is 3635.75; 1664.65; 2070.2; 106.9. Conclusion: Susceptibility of Aedes aegypti mosquito, Aedes albopictus, Culex quinquefasciatus, Anopheles subpictus have variations in susceptibility. Value lethal time showed that the insecticide Cypermethrin 0.05% takes a long time to kill mosquito.
