RÉSUMÉ
A modified sweeping method was developed using a cotton sweep net for control of Ae. aegypti immatures in 200 liter (44 gallon) metal drums which are major sources of breeding in Yangon. Laboratory experiments revealed that with only 4 sweeps (approximately 10 minutes duration), the mean % removal (+/- SD) of Ae. aegypti fourth stage larvae was 88.5% +/- 1.47. This was followed by a field study undertaken in Sanchaung township, Yangon. Twenty-eight drums with moderate (< 500 immatures) to high (> or = 500 immatures) Ae. aegypti density were tested in the field. It was found that with only 4 sweeps per drum, a total of 24,886 immatures were removed out of 29,155 immatures in these 28 drums, giving a mean % removal per drum of 85.36% +/- 10.74 (range = 55.54-98.62%). This sweeping method is simple, cost-effective, and readily accepted by the community. It could be an appropriate technology for control of the dengue hemorrhagic fever (DHF) vector Ae. aegypti.
