BACKGROUND The control of leishmaniasis, a tropical neglected disease, has been concern of Iranian health authorities due to the increasing number of cases during the last two decades. The objective of this study was to determine deltamethrine residue on the impregnated bed nets using HPTLC technique in a leishmaniasis control program in Iran. METHODS During this experimental study, a total o...

 pyrethroid-impregnated bednets have been shown to be one of the most promising tools that have emerged in recent years to control malaria.mosquito may be physically irritated by pyrethroid reducing the time searching for blood meals,or driving them away.permethrin impregnated nets also may deter a proportion of mosquitoes from entering houses.irritant effect of nets treated with 200 mg and 500...

BACKGROUND Studies indicate that physical damage to long-lasting insecticide-treated nets (LLINs) occurs at a surprisingly rapid rate following net distribution. To what extent does such damage affect the impact of LLINs? Can vectors pass a compromised LLIN barrier to bite? Do more resistant vectors enter the insecticide-treated nets (ITNs) through holes? METHODS The study was carried out in ...

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 ...

OBJECTIVE To assess the effectiveness of impregnated mosquito nets, indoor residual spraying and larval control relative to the impacts of climate variability in the decline of malaria cases in Eritrea. METHODS Monthly data on clinical malaria cases by subzoba (district) in three zobas (zones) of Eritrea for 1998-2003 were used in Poisson regression models to determine whether there is statis...

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...

Background. This study evaluated dose-response, persistence, irritancy and wash resistance of mosquito nets treated with a synergized natural pyrethrins-formulation against Anopheles gambiae s.s. Methods. Multi-filament polyester netting was impregnated to deposit doses of pyrethrins equivalent to 75 mg/m2, 100 mg/m2, 250 mg/m2, 500 mg/m2, and 1000 mg/m2. Dose-response, persistence, and wash re...

This article reviews the current status of the use of insecticide-impregnated mosquito nets and other impregnated materials in the Americas. Studies from Brazil, Colombia, Ecuador, Guatemala, Peru, Suriname, and Venezuela are examined. It is concluded that most studies have suffered from experimental design errors, short duration problems, and/or inadequate measurement of health indicators. The...
