The resistance status of Aedes aegypti larvae to Temephos in Depok, Sleman, Yogyakarta
Abstract
There are still many cases of dengue hemorrhagic fever and tend to increase
over time. One strategy to reduce the increase in cases of dengue infection is
to eradicate Aedes aegypti as a vector using insecticides. The use of insecticides
for a long time can cause resistance. The purpose of this study was to determine
the resistance status of Aedes aegypti larvae against temephos in Depok, Sleman.
This quasi experimental test was carried out on 3rd instar larvae of aedes
aegypti from RW 9 and 10 Minomartani, Depok, Sleman. The treatment group
was exposed 0.02 ppm temephos for 24 hours. The analysis was presented in the
form of percentage of larval mortality and resistance categories based on WHO
guidelines. The mortality percentage of Aedes aegypti larvae in RW 9 was 100%,
while the mortality from RW 10 was 97%. Aedes aegypti larvae in Depok district,
Sleman are still susceptible to temephos at a dose of 0.02 ppm.
