({D}iptera: {C}ulicidae) is known to feed on plant sugars, but this is the first experimental study to consider whether it discriminates between plant species. {T}hirteen perennial plant species were selected on the basis of their local availability within the vicinity of human dwellings and larval habitats of {A}n. gambiae s.s. in western {K}enya. {G}roups of 100 or 200 mosquitoes were released into cages either with a cutting of one plant type at a time (single-plant assay) or with cuttings of all 13 plants simultaneously (choice assay), respectively, and left overnight. {I}n the choice assay, direct observations of the percentages of mosquitoes perching or feeding on each plant were recorded over four 1-h periods each night. {F}or both types of assay, mosquitoes were recaptured and the percentage that had fed on plants was assessed by testing them individually for the presence of fructose. {T}o identify which plants the choice-assay mosquitoes had fed on, gas chromatography ({GC}) profiles of samples of mosquito homogenates were compared with {GC} profiles of extracts from relevant parts of each plant. {F}our of the plants that were observed to have been fed on most frequently in the choice assay ({P}arthenium hysterophorus {L}., {T}ecoma stans {L}., {R}icinus communis {L}., and {S}enna didymobotrya {F}resen) were also shown to have been ingested most often by mosquitoes in both types of assay, suggesting that {A}n. gambiae is differentially responsive to this range of plants, regardless of whether the plants were presented singly or mixed together. {S}ignificantly more females than males fed on plants, with the exception of {P}. hysterophorus {L}., one of the plants most frequently fed on. {F}or most plant species (ten of 13), {GC} profiles indicated that {A}n. gambiae obtained sugars primarily from flowers. {T}he exceptions were {R} hysterophorus {L}., {L}antana camara {L}. and {R}. communis {L}., on which {A}n. gambiae fed more often from leaves and stems than from flowers.}, keywords = {{A}nopheles gambiae ; {K}enya ; malaria ; nectar ; plant feeding ; {KENYA}}, booktitle = {}, journal = {{M}edical and {V}eterinary {E}ntomology}, volume = {21}, numero = {1}, pages = {103--111}, ISSN = {0269-283{X}}, year = {2007}, DOI = {10.1111/j.1365-2915.2007.00672.x}, URL = {https://www.documentation.ird.fr/hor/fdi:010037936}, }
