Chen, C D; Nazni, W A; Seleena, B; Moo, J Y; Azizah, M; Lee, H L (2007)The comparative oviposition preferences of Aedes aegypti to water from storm-water drains* and seasoned tap water were evaluated in the laboratory. The sample was collected from concrete storm-water drains with stagnant clear water in a dengue-endemic site, Taman Samudera, Selangor. Ae. aegypti adults were given a blood meal and released into the cage. Gravid females were given a choice between drain water and seasoned tap water for egg deposition. In a no-choice test, there was no significant difference in the numbers of eggs, larvae, pupae and ...

Nazni, W A; Selvi, S; Lee, H L; Sadiyah, I; Azahari, H; Derric, N; Vasan, S S (2009-12)Two strains of Aedes aegypti, a RIDL® strain (MyRIDL513A) and a laboratory strain (MyWT), were used in the insecticide-susceptibility study. Two-to-five-day-old female mosquitoes from both strains were tested for their susceptibility against seven insecticides from the class of organophosphate, carbamate, pyrethroids and organochlorine. The adult bioassay was performed according to WHO standard procedures. The 50% lethal time (LT50) value was determined for each strain against the seven insecticides. Both the MyRIDL513A and MyWT strains were ...
