Kepadatan Vektor Dan Status Resistensi Nyamuk Demam Berdarah Dengue (Aedes Aegypti) Terhadap Malation Di Kota Bitung Tahun 2017

Abstract

The success of DBD vector control depends on the vector susceptibility status of the insecticide used. Periodic monitoring of susceptibility to insecticide vulnerability is important. The purpose of this research is to know the vector density, and the susceptibility status of Dengue Hemorrhagic Mosquito (Ae.aegypti) to the malation in Bitung City. The benefits of this study are expected to provide information on the vector density and the susceptibility status of dengue fever mosquitoes (Ae.aegypti) to malathion in Bitung City so that it becomes the evaluation material of DHF control program in planning in order to suppress the increase of DHF case in Bitung City. This study is an observational descriptive study to obtain an overview of vector density and insecticide susceptibility status (malathion) in Bitung city. The population in the study was the house and population of Ae.aegypti mosquitoes while the sample was a vector density of 100 houses. The results of the research The vector density is House Index (HI) = 44, Container Index (CI) = 21.4 and Breteau Index = 73 all show high density of larvae and test results of Ae.aegypti mosquito susceptibility status using malathion o, 8% impregnated paper and WHO standard susceptibility test, that Ae.aegypti mosquito susceptibility to malathion was done by counting the number of dead mosquitoes at one hour and 24 hours after exposure was stated to be resistant to malathion (mosquito mortality <80%). So immediately carry out the rotation of other insecticides by first testing the insecticides to be used.
