  abstract = {{B}ackground : {A} previous study showed for {A}nopheles gambiae s. s. a gradation of feeding preference on common plant species growing in a malaria holoendemic area in western {K}enya. {T}he present follow-up study determines whether there is a relationship between the mosquito's preferences and its survival and fecundity. {M}ethods: {G}roups of mosquitoes were separately given ad libitum opportunity to feed on five of the more preferred plant species ({H}amelia patens, {P}arthenium hysterophorus, {R}icinus communis, {S}enna didymobotrya, and {T}ecoma stans) and one of the less preferred species ({L}antana camara). {T}he mosquitoes were monitored daily for survival. {S}ugar solution ( glucose 6%) and water were used as controls. {I}n addition, the fecundity of mosquitoes on each plant after (i) only one blood meal ( number of eggs oviposited), and (ii) after three consecutive blood meals ( proportion of females ovipositing, number of eggs oviposited and hatchability of eggs), was determined. {T}he composition and concentration of sugar in the fed-on parts of each plant species were determined using gas chromatography. {U}sing {SAS} statistical package, tests for significant difference of the fitness values between mosquitoes exposed to different plant species were conducted. {R}esults and {C}onclusion: {A}nopheles gambiae that had fed on four of the five more preferred plant species ( {T}. stans, {S}. didymobotrya, {R}. communis and {H}. patens, but not {P}. hysterophorus) lived longer and laid more eggs after one blood meal, when compared with {A}n. gambiae that had fed on the least preferred plant species {L}. camara. {W}hen given three consecutive blood-meals, the percentage of females that oviposited, but not the number of eggs laid, was significantly higher for mosquitoes that had previously fed on the four more preferred plant species. {T}otal sugar concentration in the preferred plant parts was significantly correlated with survival and with the proportion of females that laid eggs. {T}his effect was associated mainly with three sugar types, namely glucose, fructose, and gulose. {E}xcept for {P}. hysterophorus, the results suggest that feeding by mosquitoes on preferred plant species under natural conditions results in higher fitness-related benefits, and that the sugar content in preferred plant parts is largely responsible for these effects.},
