Long lasting pyrethroid treated bednets are the most important tool for preventing malaria. Pyrethroid resistant Anopheline mosquitoes are now ubiquitous in Africa, though the public health impact remains unclear, impeding the deployment of more expensive nets. Meta-analyses of bioassay studies and experimental hut trials are used to characterise how pyrethroid resistance changes the efficacy o...

Long-lasting insecticidal nets (LLINs) have been advocated as an effective tool against malaria transmission. However, success of this community based intervention largely depends on the knowledge and practice regarding malaria and its prevention. According to the national strategy plan on evaluation of LLINs (Olyset nets), this study was conducted to determine the perceptions and practices abo...

Despite the free distribution of insecticide impregnated nets, malaria is still cause many deaths, particularly among children under 5 years old, casting doubt on real use these mosquito nets by parents. The present work aimed to identify factors associated with low nets. This was a cross-sectional study an analytical aim, carried out in locality Fô-Bouré (Sinendé) 2019 old and their A cluster ...

An insect growth regulator, pyriproxyfen, has been used for the control of a range of pest insects, including mosquitoes. Pyriproxyfen is effective in inhibiting adult emergence and sterilizing adult females. The Asian tiger mosquito, Aedes albopictus (Skuse), is an important vector of dengue and chikungunya, and is expanding its distribution throughout Europe and the Americas. In the present s...

general knowledge of at risk people regarding malaria is key element to facilitate appropriate treatment and prevention behaviours. the aim of this study was to assess the family heads' understanding of malaria transmission, signs and symptoms, and preventive measures in malaria-affected districts of iran.in 2009 in a cluster randomized cross-sectional survey data were collected from the heads ...

This review study envisages the role of insecticide-elicited mosquito behaviour for disease eradication programmes. Changes in due to insecticides may, at times, be more practical importance than actual lethal effect insecticide, especially if these changes help disrupt contact between man and mosquito. Two important aspects behaviour, either repellency or irritability biting patterns response ...

The degree of effectiveness of mosquito nets against malaria in the Americas has remained uncertain. We carried out a case-control study of net use and mild malaria in the Amazonas state of Colombia. Two hundred ninety cases were enrolled via the Health Department services, and 977 community-based controls matched for age, sex, and place of residence. We found that a large proportion of the pop...

Background: Insecticide-treated nets represent currently a key malaria control strategy, but low insecticide re-treatment rates remain problematic. OlysetTM nets are currently one of two longlasting insecticidal nets recommended by WHO. An assessment was carried out of the effect of OlysetTM nets after seven years of use in rural Tanzania. Methods: A survey of OlysetTM nets was conducted in two...

Spatial analyses of the effect of insecticide (permethrin)-treated bed nets (ITNs) on nearby households both with and without ITNs was performed in the context of a large-scale, group-randomized, controlled mortality trial in Asembo, western Kenya. Results illustrate a protective effect of ITNs on compounds lacking ITNs located within 300 meters of compounds with ITNs for child mortality, moder...
