Distribution of Voltage-gated Sodium Channel Mutations in Aedes Aegypti Populations from Rural Areas of Indonesia
Abstract
Introduction:
Semarang has been one of the endemic districts; since 2017, it has contributed to high dengue cases in Central Java. The study was conducted to see the mutation in the Voltage-Gated Sodium Channel (VGSC) Aedes aegypti genera.
Materials and Methods:
Aedes aegypti from 6 sub-districts in Semarang were examined, where each sub-district was taken from 2-3 villages endemic areas with high fogging intensity in Semarang. Ten larvae samples were taken from each village.
Results and Discussion:
The results showed that the resistant samples were 48.4% heterozygous and 51.6% homozygous resistant from Bawen, 100% heterozygous resistant from Bandungan, 73.3% heterozygous and 26.7% homozygous resistant from West Ungaran, 65% heterozygous and 35% homozygous resistant from Sumowono, 23.3% heterozygous and 66.7% homozygous resistant, and 10% still susceptible from Ambarawa, and 30% heterozygous and 70% homozygous resistant from East Ungaran districts.
Conclusion:
Based on the results of the molecular test, the Ae. Aegypti in Semarang Regency has proven resistance to the pyrethroid insecticide cypermethrin.
