Tóm tắt : | Dengue Bulletin. 2007 Dec; 31: 124-130. 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 adults colonized from the drain water and seasoned tap water (p>0.05), indicating that Ae. aegypti oviposit their eggs on a substrate which is readily available. In a choice test, the number of eggs laid by Ae. aegypti in drain water (1630.67 ± 204.26) was significantly more than that in seasoned tap water (221.33 ± 53.18) (p0.05), indicating that water from the drain did not contain high organic content. Significant water conductivity (p |
