Abstract:
The study was designed to evaluate the effectiveness of bed-net impregnation with Ale l0SC at a dose 25mg a.i/m2 based on bioassays, entomological indices and to evaluate side effects and the influence of washing of bed-nets in terms of insecticide residual effects. The trials were conducted from November 2003 to November 2004 in Quyet Chien commune, Hoa Binh province's Tan Lac district. Polyester bed-nets impregnated with Ale l0SC at dose of 25mg ai/m2 were found to have 6-month residual effects and to remain effective in malaria vector control after one wash (60 days after treatment). Ale l0SC bed-net impregnation were found to reduce the density of day time indoor resting and human biting anopheline mosquitoes. There are unsignficant side effects among spraymen, dippers and villagers in the treatment areas caused by bed-net impregnation at dose of 25mg ai/m2 were observed.
