Comparative oviposition preferences of Aedes (Stegomyia) aegypti (L.) to water from storm water drains and seasoned tap water.
AbstractThe 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

Khoury, S.; Graczyk, T.; Burnham, G.; Jurdi, M.; Goldman, L. (2016-08)Drinking water at Shatila Palestinian Refugee Camp in Beirut, Lebanon is of poor quality and unpredictably intermittent quantity. We aimed to characterize drinking water sources and contamination at Shatila and determine how drinking water can be managed to reduce community health burdens. We interviewed the Popular Committee, well owners, water vendors, water shopkeepers and preschool administrators about drinking water sources, treatment methods and the population served. Water samples from the sources and intermediaries were analysed for ...
