Spatial Distribution Of The Conventional Resistance Of Aedes Aegypti Mosquito And Case Of Dengue Fever, Kediri, Indonesia, 2020

Abstract

Dengue Hemorrhagic Fever (DHF) is a health problem in the world. The highest number of DHF sufferers in Kediri Regency in 2016 was in the Districts of Pare, Ngasem and Kunjang. DHF vector control techniques include: fogging using the active ingredient malathion for the adult stage of mosquitoes. Vector resistance to insecticides is a global phenomenon, especially for vector-borne disease control program managers and is the single obstacle to the success of chemical vector control. Detection of vector resistance using conventional detection with the standard method of WHO Susceptibility test using impregnated paper. The purpose of the study was to describe the Spatial Distribution of Conventional Resistance of Aedes aegypti Mosquitoes in Kediri Regency. This type of True Experiment research uses Aedes aegypti mosquitoes in dengue-endemic areas in Kediri Regency. The research sample was the 3rd offspring (F3) of the adult Aedes aegypti mosquito. Exposing the Aedes aegypti mosquito with 5% malathion insecticide with a contact time of 45 and 60 minutes. Data analysis includes the percentage of mosquito mortality, determining resistance status by referring to the WHO category standard and describing mosquito resistance and connecting the percentage of mosquito deaths with dengue fever cases using the geoda application. amples of the test biota (Aedes aegypti mosquito larvae) were obtained from 11 (eleven) sub-districts, namely Pare, Ngasem, Kandat, Kunjang, Purwoasri, Wates, Gampeng, Papar, Puncu, Kayen, Kandangan. The mortality percentage of Aedes aegypti mosquitoes exposed to Malathion 5% with exposure within 60 minutes is less than 90%, namely Pare District with resistant status, while ten (10) other districts are above 90% with vulnerable status. The percentage of sub-districts that use malathion insecticides for more than 10 years is 54.54% and the use of malathion insecticides is following the procedures set by the government. It is necessary to rotate the use of insecticides in controlling the DHF vector, monitoring and evaluating the susceptibility status of the DHF vector to insecticides used by the Kediri District Health Office every 1-2 years, as well as monitoring and evaluating the density of mosquitoes.
