Abstract Background Pyrethroid resistance poses a major threat to the efficacy of insecticide-treated nets (ITNs) in Burkina Faso and throughout sub-Saharan Africa, particularly where is present at high intensity. For such areas, there are alternative ITNs available, including synergist piperonyl butoxide (PBO)-based dual active ingredient as Interceptor G2 (treated with chlorfenapyr alpha-cypermethrin). Before deploying on large scale it crucial characterize profiles primary malaria vector...

Malaria, one of the world's greatest public health challenges, is an endemic disease with stable transmission in Togo. Combating malaria requires effective vector control. This study provides temporal data on insecticide resistance status major Anopheles gambiae sensu lato (s.l.) from Togo.Two to 5 days old females An. s.l., originating three localities (Baguida, Kovié, Kolokopé) were subjected insecticide-impregnated papers during 3 years (2012, 2013, 2016) as follows: organochlorides (4%...

Entomological surveillance of lymphatic filariasis and malaria infections play an important role in the decision-making national programs to control, or eliminate these both diseases. In areas where diseases prevalence is low, a large number mosquitoes need be sampled determine vectors infection rate. To do this, efficient mosquito collection methods must used. This study part this framework, assess appropriate for xenomonitoring coexistence context with Burkina Faso. Mosquito collections...

A novel strategy applying an organophosphate-based insecticide paint on doors and windows in combination with long-lasting insecticide-treated nets (LLINs) was tested for the control of pyrethroid-resistant malaria vectors a village setting Vallée du Kou, rice-growing area west Burkina Faso. Insecticide Paint Inesfly 5A IGR™, comprised two organophosphates insect growth regulator, applied to pyrethroid-treated LLINs. The killing effect monitored 5 months by early morning collections...

Twenty years after the latest publications performed on parasitological indices of malaria transmission in northwest second city Burkina Faso, it was important to update epidemiological profile children under age 15 years. The objective this study determine and compare parameters by season, area, two zones (rice savanna) Bobo-Dioulasso, Faso. Overall, results showed that there no significant difference within fifteen between rice site savannah whatever season (<mml:math...

Introduction: Lymphatic filariasis (LF) and malaria are two vector-borne diseases which parasites can simultaneously infect human or mosquito. In Burkina Faso, studies mainly focused on the control of these independently. Hence, there is a lack information their co-transmission to both vector. The present study aimed at providing baseline data from endemic areas in Faso towards successful integrated management diseases. Methods: was carried out six sites distributed East, Center-East...
