摘要:AbstractIn 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.
