  abstract = {{B}ackground: {T}he {H}uman {B}lood {I}ndex ({HBI}, proportion of bloodmeals of a mosquito population obtained from man) is relevant to epidemiological assessment and to the modification of measures to interrupt malaria transmission since the vectorial capacity of the vector varies as the square of the {HBI}. {A}nopheles pseudopunctipennis is a main malaria vector in {S}outh {A}merica. {U}nfortunately, few data exist concerning {HBI} values in its range of distribution and none from {B}olivia where this species is considered as an important malaria vector in the central {A}ndes. {M}ethods: {T}he host choice of {A}n. pseudopunctipennis has been studied in {M}ataral, a characteristic village of the central {A}ndes of {B}olivia. {M}osquito host feeding preference experiments (equal accessibility to host in homogenous environment) were monitored using baited mosquito nets in latin square designs. {H}ost feeding selection experiments (natural feeding pattern in heterogeneous environment) was measured by bloodmeal analysis, using {ELISA} to determine the origin of blood. {M}osquito bloodmeals were collected on various occasions, using various techniques in a variety of sampling sites. {A} survey of the possible blood sources has also been carried out in the village. {D}ata were analysed with the forage ratio method. {R}esults: {A}n. pseudopunctipennis chooses amongst hosts. {S}heep, goats, donkeys and humans are the preferred hosts, while dogs, pigs and chicken are rarely bitten. {A}n. pseudopunctipennis has an opportunistic behaviour, in particular within the preferred hosts. {T}he {HBI} in {M}ataral is approximate to 40% and in the central {A}ndes, may range from 30-50%, in accordance to other findings. {A} high proportion of mixed meals were encountered (8%), and cryptic meals are likely more numerous. {T}here was no difference amongst the {HBI} from parous and nulliparous mosquitoes. {C}onclusion: {F}orage ratio analysis is a powerful tool to interpret mosquito host choices. {H}owever, refinements in sampling strategies are still needed to derive accurate and precise {HBI}s that could be computed to compare or follow epidemiological situations. {T}he low antropophily of {A}n. pseudopunctipennis, associated with changing environmental conditions, leads to unstable malaria ({P}lasmodium vivax) transmission in the central {A}ndes. {T}he opportunistic behaviour of this vector may be used to attract mosquitoes to insecticide. {Z}ooprophylaxis is a promising alternative control strategy.},
