Tingkat Kematian Anopheles Vagus Yang Terpapar Insektisida Permethrin 2% (W/W) di Dalam Serat Benang Kelambu (Mortality Rate of Anopheles Vagus Exposed By Permethrin 2% (w/w) in Fiber Yarn Net)
Various efforts to control mosquito-borne diseases have been done i.e the use of insecticide¬treated nets (ITN). The aim of this study was to determine the insecticide permethrin in the nets to control Anopheles vagus mosquito that were widely distributed in the village of Tanjung Seleman, Muara Enim district based upon age and frequency of laundering. An experimental research using a complete randomized design was conducted in April-December 2010. Data regarding the effective¬ness ofpermethrin against Anopheles, were collected through biossay test (WHO cone test) with con¬tact method. Entomology bioassay data is the average of mosquito mortality for nets that given in 2006 was 66. 5%, for the nets in 2007 the mortality rate reached 67. 3%, and for mosquito nets in 2008 the mortality rate reached 67.5%. It shows that there were differences effect on mortality of An. vagus which exposed to mosquito net that has never been washed with the washing 1 -3 times or more, white the mortality 4 mosquito that exposed to different age al nets shows no significantly difJerence. Percentage of An. vagus mortality that exposed by permethrin insectiside is still high.
