  abstract = {{T}he urban area of {D}akar, {S}enegal, contains more than 5,000 market-garden wells that provide permanent sites for mosquito larvae, in particular #{A}nopheles arabiensis$ {P}atton, the major vector of malaria. {A} study of the bioecology of mosquito larvae was conducted over 1 yr with a monthly visit to 48 of these wells. {O}verall, 9,589 larvae were collected of which 80.1% were #{C}ulcinae$ and 11.9% #{A}nophelinae$. {L}arvae from stages 2 and 4 (n = 853) were identified to 10 species. #{A}n. arabiensis$ represented 86% of the anophelines collected and #{A}n. ziemanni$ {G}runberg 14%. {T}he most common #{C}ulcinae$ species included #{A}edeomyia africana$ {N}eveu-{L}emaire, #{C}ulex quinquefasciatus$ {S}ay, and #{M}imomyia splendens$ {T}heobald. {M}aximum anopheline abundance was observed at the end of the dry season in {J}une, whereas maximum #{C}uliniae$ abundance was observed at the end of the rainy season in {S}eptember. {M}ost wells (67%) did not harbor any #{A}n. arabiensis$ larvae and in the remaining 33% the larval abundance was low, averaging 0.54 larvae in stages 3-4 per tray sample. {T}o identify factors that determine the abundance of larvae in these wells, a co-inertia (multivariate) analysis was carried out to account for physicochemical variables (depth, turbidity, temperature, p{H}, conductivity, {N}a(+), {HCO}3(-), {CO}3(--), and {NO}3(-) concentrations) and biological variables (abundance of mosquito species, predators (e.g. fish, #{D}ystiscidae$, #{N}otonectidae$, odonates), molluscs (#{B}ulinus$ and #{B}iomphalaria$), and surface plants (water lettuce, #{L}emma$ and filamentous algae). {T}he co-inertia analysis indicated that the abundance of #{A}n. arabiensis$ was associated with #{C}s. quinquefasciatus$ and #{C}x. decens$ for the physiochemical data but was not associated with other mosquito species for floro-faunistic data...
