  abstract = {{B}ackground: {A} severe outbreak of dengue occurred in {B}urkina {F}aso in 2016, with the most cases reported in {O}uagadougou, that highlights the necessity to implement vector surveillance system. {T}his study aims to estimate the risk of arboviruses transmission and the insecticide susceptibility status of potential vectors in four sites in {B}urkina {F}aso. {M}ethods: {F}rom {J}une to {S}eptember 2016, house-to-house cross sectional entomological surveys were performed in four cities stretching along a southwest-to-northeast railway transect. {T}he household surveys analyzed the presence of {A}edes spp. larvae in containers holding water and the {W}orld {H}ealth {O}rganization ({WHO}) larval abundance indices were estimated. {WHO} tube assays was used to evaluate the insecticide susceptibility within {A}edes populations from these localities. {R}esults: {A} total of 31,378 mosquitoes' larvae were collected from 1,330 containers holding water. {A}edes spp. was the most abundant (95.19%) followed by {C}ulex spp. (4.75%). {A}edes aegypti a key vector of arboviruses ({ARBOV}) in {W}est {A}frica was the major {A}edes species found (98.60%). {T}he relative larval indices, house index, container and {B}reteau indexes were high, up to 70, 35, and 10, respectively. {A}edes aegypti tended to breed mainly in discarded tires and terracotta jars. {E}xcept in {B}anfora the western city, {A}e. aegypti populations were resistant to deltamethrin 0.05% in the other localities with low mortality rate under 20% in {O}uagadougou whereas they were fully susceptible to malathion 5% whatever the site. {I}ntermediate resistance was observed in the four sites with mortality rates varying between 78 and 94% with bendiocarb 0.1%. {C}onclusions: {T}his study provided basic information on entomological indices that can help to monitor the risks of {ARBOV} epidemics in the main cities along the railway in {B}urkina {F}aso. {I}n these cities, all larval indices exceeded the risk level of {ARBOV} outbreak. {A}edes aegypti the main species collected was resistant to deltamethrin 0.05% and bendiocarb 0.1% whereas they were fully susceptible to malathion 5%. {T}he monitoring of insecticide resistance is also important to be integrated to the vector surveillance system in {B}urkina {F}aso.},
