Aedes Mosquitoes Resistance in Urban Community Setting

In response to high incidence of Dengue cases in the less affordable settlements of Malaysia, the susceptibility of Aedes mosquitoes should be assessed to identify the 50% knockdown time (KT50) of adult Aedes mosquitoes to malathion. Wild strain mosquitoes from Shah Alam has shown potential to insecticide resistance with the resistance ratio of 2.2 with 95% mortality. In contrast, wild strain from Pantai Dalam may have developed insecticide resistance with the resistance ratio of 2.4 with 78% mortality. Health education and community should be propagated to promote healthy environment by developing positive attitude and practice towards Dengue prevention.
