OBJECTIVE To compare the efficacy of seven pyrethroid insecticides for impregnation of mosquito nets, six currently recommended by WHO and one candidate (bifenthrin), under laboratory conditions. METHODS Tests were conducted using pyrethroid-susceptible and pyrethroid-resistant strains of Anopheles gambiae and Culex quinquefasciatus. Knock-down effect, irritancy and mortality were measured us...

BACKGROUND In Ecuador, dengue virus (DENV) infections transmitted by the Aedes aegypti mosquito are among the greatest public health concerns in urban coastal communities. Community- and household-level vector control is the principal means of controlling disease outbreaks. This study aimed to assess the impact of knowledge, attitudes, and practices (KAPs) and social-ecological factors on the p...

BACKGROUND Insecticide treated nets (ITNs) have been proved as one of the most effective ways of reducing malaria morbidity and mortality in children and pregnant women. Proper use and care of insecticide treated nets reduce malaria health risk to children. OBJECTIVE To determine maternal use of insecticide treated nets in the prevention of malaria among children under five years in Nyamira d...

Mosquitoes (Diptera: Culicidae) are the most medically important arthropods worldwide, vectoring numerous agents that negatively affect humans, including dengue, arboviral encephalitides and malaria parasites. These mosquito-borne pathogens adversely affect millions of people annually, and the total burden of diseases associated with mosquitoes is well documented (e.g. see Sachs and Malaney 200...

Dengue fever is a common mosquito-borne viral infectious disease in the world and widely spread, especially tropical subtropical regions. At this moment, one of best ways to fight prevent mosquito bites. In study, we present mathematical model that carefully considers personal protection for humans. It an epidemiological translates dengue through system differential ordinary equations which tak...

The study assessed the operational feasibility and acceptability of insecticide-treated mosquito nets (ITNs) in one Primary Health Centre (PHC) in a falciparum malaria endemic district in the state of Orissa, India, where 74% of the people are tribes and DDT indoor residual spraying had been withdrawn and ITNs introduced by the National Vector Borne Disease Control Programme. To a population of...

Owing to the development of pyrethroid resistance in Anopheles gambiae, there is a need to develop chemical alternatives for use on mosquito nets. Synthetic insect repellents are widely used for personal protection as skin or clothing applications. The efficacy of repellent-treated nets (RTN) was evaluated in experimental huts in Côte d'Ivoire against pyrethroid-resistant populations of An. gam...
