b a ckground: the long-lasing insecticide impregnated nets (llins) is considered as an effective tools for malaria vector control. the aim of this study was to evaluate the residual efficacy of alpha-cypermethrin long lasting im- pregnated nets (llin-interceptor®) against anopheles stephensi using tunnel test. m e t hods: the wash-resistance of interceptor® nets were assessed under laboratory c...

Its relatively low cost and high surface area makes activated carbon an ideal adsorbent candidate for H2S removal. However, physical adsorption of is not very effective; therefore, methods to facilitate reactive oxidation on carbons are interest. The performance removal non-impregnated, impregnated, doped in low-temperature syngas was evaluated fixed-bed breakthrough tests. importance oxygen co...

The use of long lasting insecticide nets (LLINs) treated with pyrethroïd is known for its major contribution in malaria control. However, LLINs are suspected to induce behavioral changes in malaria vectors, which may in turn drastically affect their efficacy against Plasmodium sp. transmission. In sub Saharan Africa, where malaria imposes the heaviest burden, the main malaria vectors are widely...

BACKGROUND & OBJECTIVE Insecticide treated mosquito nets are increasingly being used in malaria control programmes. One of the problems with the treatment of bed nets with conventional formulations of insecticides was that regular washing of treated nets diminish insecticidal effect. Lambdacyhalothrin 2.5 capsule suspension (CS) (2.5% a.i., w/v), a new water-based microencapsulated formulation ...

an interventional field trial study was carried out in the dehdahst area, kohgiloyeh & buyer ahmad province, iran, during 1997-1998. efficacy of deltamethrin-impregnated bednet at target dosage of 25 a.i. mg/m2 and the incidence of malaria were compared in treated and untreated villages. in this area anopheles superpictus is the dominant species and the activity of the species occurs in one pea...

OBJECTIVE Universal coverage with insecticide-treated bed nets is a cornerstone of modern malaria control. Mozambique has developed a novel bed net allocation strategy, where the number of bed nets allocated per household is calculated on the basis of household composition and assumptions about who sleeps with whom. We set out to evaluate the performance of the novel allocation strategy. METH...
