Dengue Hemorrhagic Fever (DHF) in Indonesia is an endemic disease with morbidity level tends to
increase from year to year and extends to 400 regencies/cities from 474 regencies/cities in Indonesia. This
disease even frequently causes Outbreaks (KLB). One of the dengue controls is chemical control. Chemical
control by using insecticides is the most popular form of control in the society because it is easy to
implement. Insecticides are most commonly used are lambda cyhalothrin and sipermetrin because it is
cheap and readily available. The use of the same insecticide for around 2-20 years and improper dosage
can cause mosquitoes to become resistant.
This study aimed to test the susceptibility of mosquitoes to Lamdacyhalothrin and cypermethrin.
This research was experimental and the study design used "with Pretest-Posttest Control Group".
Susceptibility Test used 500 Aedesaegypti mosquito as sample and using 20 tubes with ach tube is filled 25
mosquitoes. 0.05% of Lamdacyhalothrin and 0.05% of cypermethrin were put in 8 tubes while for control
was 4 tubes containing plain white paper. Mosquitoes were exposed for 1 hour, then transferred into paper
cup containing cotton containing sugar water, then stored for 24 hours. The observation was then carried
out and calculating the percentage of dead mosquitoes.
The results showed the number of dead mosquitoes with Lamdacyhalothrin was 7%, included in
the category of resistance (WHO). The number of dead mosquitoes with cypermethrin was 2.5% which is
also in the category of resistance. This susceptibility status categories are taken based on the criteria of the
WHO, the mortality <80% means resistant, the mortality of 80-97% are tolerant, and 98% - 100% is
susceptible (WHO, 1975)
The society is advised  to use insecticide in the right dose, limiting the excessive use of
insecticides and if necessary, only to use non-chemical control.
