dc.description.abstractA study was carried on Aedes albopictus mosquito in residential areas and its fitness cost in response to the insecticide exposure. The study to evaluate the current knowledge level on Aedes mosquitoes and dengue among Penang residence in urban Sg. Dua and sub-urban Batu Maung involved 202 respondents mainly on the observation of general Aedes' mosquito behaviour and its preventive measure, and lifestyle (on usage of artificial light) in changing the behaviour of Aedes mosquitoes. There is a direct link between the knowledge of the Aedes biting frequency with human lifestyle on the light use. However, the level of knowledge is poor on Aedes mosquitoes and dengue in both urban and sub-urban respondents. Following the survey, to investigate the effects of malathion and permethrin insecticides on the life history of Ae. albopictus mosquitoes were chosen for subsequent studies. The female mosquitoes were exposed to sub-lethal concentration of 1.5% malathion and 0.2% permethrin using WHO adult bioassay and female survivors were evaluated for their fitness parameters. We discovered 0.2% permethrin have significantly more effects on the fitness cost of Ae. albopictus, even though had developed resistance towards permethrin. Permethrin has decrease the fecundity, shorten the development periods on each larval stages and influence the sex ratio with more emerge male of Ae. albopictus. Regarding the increasing concern on the current activity of Ae. albopictus and Cx. quinquefasciatus mosquitoes in the residential areas, 24 hour trapping was conducted at urban Sg. Dua and sub-urban Batu Maung residence area using two different traps; BG- Sentinel Trap and CDC Fay-Prince Light Trap. CDC Fay-Prince light traps was most effective in trapping Cx. quinquefasciatus.en_US
