  abstract = {{B}ackground: {S}everal cases of malaria are frequently recorded during the dry period in {O}uagadougou town ({B}urkina {F}aso). {T}his has led to the design of a series of studies focusing on both parasitological and entomological investigations intended to provide relevant health data on the risk of local malaria transmission according to the way of urbanisation. {M}ethods: {A} cross-sectional entomological survey was carried out in various districts of {O}uagadougou in {A}pril and {O}ctober 2006. {A}dult malaria vectors were collected using {CDC} traps and indoor insecticide spraying performed in four houses during four consecutive days/nights. {I}ntensive larval sampling was also done in available water ponds throughout the study sites. {R}esults: {I}n {A}pril, the anopheline breeding sites consisted only of semi-permanent or permanent swamps located mainly in the two peripheral districts. {D}espite the presence of anopheline larvae in these breeding sites, less than five {A}nopheles gambiae s.l. adults were caught by {CDC} traps and indoor insecticide spraying. {I}n {O}ctober, additionally to the permanent breeding sites reported in {A}pril, some rainfall swamps were also found positive to anophelines. {T}he number of adults' mosquitoes was higher than that collected in {A}pril (2 vs 159 in {O}ctober). {O}ut of 115 larvae of {A}n. gambiae s.l. analysed by {PCR} in {A}pril, 59.1% (68/115) were identified as {A}nopheles arabiensis, 39.1% (45/115) as {A}n. gambiae {M} while the {S} form represented less than 2%. {O}verall 120 larvae and 86 females were identified by {PCR} in {O}ctober as {A}n. gambiae {M} form (51%) and {A}n. arabiensis (42.2%). {T}he {S} form represented only 6.8%. {T}he global sporozoite rate recorded was high (6.8%) and did not differ between the districts except in the central district where no positive mosquito was detected. {C}onclusion: {A}lthough only few adults' mosquitoes were actively caught during the driest month, malaria vectors persisted all year long that increases the risk of urban malaria transmission. {T}he distribution of breeding sites and especially the occurrence of malaria vectors were more abundant in the periphery, which is more like that of a rural settlement. {T}he evolution of malaria prevalence and the factors sustaining the risk of transmission in {O}uagadougou as well in many {A}frican cities during the dry season are discussed.},
