Resistensi Aedes aegypti terhadap Insektisida Kelompok Organopospat dan Sintetik Piretroid di Provinsi Sumatera Utara dan Provinsi Jambi

Abstract

Vector control using insecticide is a major effort to control Dengue Haemorrhagic Fever. The excessive use of insecticides leads to insecticide resistance in Aedes aegypti. This study aimed to determine the resistance status of Aedes aegypti in North Sumatra and Jambi Province to malathion, deltametrin, cypermethrin, lambda cyhalothrin and alpha cypermethrin. A cross sectional study was conducted during 2015, the research location covers North Sumatera area (Tebing Tinggi, Deli Serdang, and Pematang Siantar) and Jambi (Muaro Jambi, Jambi, and Batang Hari). Susceptibility test using WHO kits was applied on F1 generation and interview with Local Public Health Officer was carried out to obtain information about the usage of insecticide in both provinces. Resistance to malathion, cypermethrin, and lambda cyhaltorhin was observed in Ae. aegypti populations from all study area. Tolerant status to deltamethrin only found in Aedes aegypti from Deli Serdang, whilst the other strains were resistant. Ae. aegypti population from all study area were tolerant to alpha cypermethrin. Malathion and cypermethrin were the only insecticide ever used in both provinces. We conclude that alpha cypermethrin was effective to combat Ae. aegypti and can be used as an alternative insecticide for dengue control program in Northern Sumatera and Jambi Province.
