Aedes aegypti mosquito’s resistance state to malathion insecticide in Surabaya, West Java Province
Abstract
Penyakit Demam Berdarah Dengue telah lama menjadi masalah kesehatan di beberapa negara Asia khususnya di Indonesia dengan angka kesakitan dan kematian tetap tinggi setiap tahun terutama pada golongan anak-anak. Pada tahun 1968 sejak ditemukan kasus demam berdarah di Jakarta dan Surabaya, sebanyak 58 orang menderita dan meninggal 24 orang (CFR 41,3%). Sampai sekarang penyakit ini telah menyebar di seluruh provinsi di Indonesia dengan jumlah kasus pada tahun 2005 mencapai 95,279 kasus, tahun 2006 kasus 114,656 dan tahun 2007 mencapai 123,828 kasus (Dep.Kes. RI. 2008). Keadaan ini erat kaitannya dengan peningkatan mobilitas penduduk sejalan dengan semakin lancarnya hubungan transportasi. Dengue haemorragic fever is a relatively common problem in Indonesia, with high mortality and morbidity cases. Control of A. aegypti using insecticide as fogging is the best and fast method. The aim of the research is to identify the susceptibility of A. aegypti againt malathion. The study started from July until December 2009. The research using the WHO “Susceptibility tes methods” in 5, 15, 30, 45, and 60 minutes contact time with three replications. The A. aegypti mosquitoes were come from some areas which categorized as high to low case area. The regression curve in mortality of field mosquitoes from high to low case indicated that the curves tended to move to the right side. Even, the result of RR95 count of A. aegypti from high case area showed less than ten times (RR95 =5,576), but these mosquito’s mortality rate were 85%, which mean the population are being tolerant againts of malathion.
