Introduction Since the pioneer work of DARRIET et al. (1 984), insecticide impregnated bed nets have clearly proved their efficacy in reducing malaria transmission and morbididy (GREENWOOD & BAKER, 1993; CHO1 et al., 1995; LENGELER et al., 1996) and even overall infant mortality (BINU et al., 1996; NEVU et al., 1996), and are now considered to be an efficient tool for malaria vector control if ...

In the study carried out in the rural district of Borkhar (Isfahan, Iran) from March 2003 to March 2004 efficacy of deltamethrin impregnated bed nets (IBs) and curtains (ICs), polyester mesh size 156 holes/ inch2, (25 holes/cm2) were compared to that of non-impregnated bed nets (NIBs) and curtains (NICs), in relation to zoonotic cutaneous leishmaniasis (ZCL) control. Deltamethrin impregnated be...

Insecticide-impregnated bed nets act as a physical barrier to repel and kill mosquitos. Community intervention trials suggest that these nets are effective in preventing malaria-related mortality and morbidity--but not malaria infection--in areas of low and moderate transmission; the results from areas of high transmission are not so encouraging. Comparison of the results from these trials and ...

a field trial was carried out in the chabahar district of sistan and baluchistan province, southeastern iran on the efficacy of mosquito nets treated with a suspension formulation of deltamethrin (k-o thrin®) against malaria vectors. treated nets were used in three villages, and in the two control villages, one used untreated nets and the other used indoor spraying with deltamethrin (wp 10%), w...

A 3-year entomological study was carried out on the transmission of malaria in a village of 900 inhabitants in a rice-growing area of Burkina Faso. In the study area inhabitants use bed nets to protect themselves from mosquito bites. In the first year of the study, baseline data were collected; in the second year, the village was divided in two parts and all the bed nets in the southern part we...

Randomized controlled trials in African settings with different intensities of malaria-transmission have shown that insecticide-treated nets are efficacious in reducing postneonatal mortality from all causes (1,2). The Gambian National Impregnated Bed-net Programme achieved an 83% net-treatment rate, and overall mortality of children aged less than five years fell by 25% a decade ago (1). Howev...

The spread of resistance to pyrethroids in the major Afrotropical malaria vectors Anopheles gambiae s.s. necessitates the development of new strategies to control resistant mosquito populations. To test the efficacy of nets treated with repellent and insecticide against susceptible and insecticide-resistant An. gambiae mosquito populations, we impregnated mosquito bed nets with an insect repell...

The Peruvian Ministry of Health has distributed insecticide-treated nets (ITNs) in the country's Amazon region since 1999. Net use is nearly universal among mestizo communities in this area, but residents traditionally use non-impregnated muslin nets. We evaluated the cultural acceptability of Ministry ITNs using qualitative methods. Our results show that nets serve various functions for users:...
