  abstract = {{T}he individual circadian periodicity in eight hosts of {P}lasmodium falciparum gametocytes is studied in {S}enegal. {T}he average time series does not present any periodicity. {A}s for filariasis ({P}ichon and {T}reuil, 2004), it could be considered that this lack of global periodicity is in fact due to the coexistence, in each host, of two completely periodic, out of phase rhythms. {H}ere we propose a simple mathematical method to test this assumption, which is confirmed. {T}here is a complete morning rhythm with peak at 10 a.m. and another evening rhythm with peak at 10 p.m., both rhythms being at equal proportions on average. {A} similar temporal pattern is suggested in {G}ambia. {T}he same morning rhythm is observed in {T}anzania, but the evening rhythm happens two hours earlier, explaining the occurrence of a global subperiodic fluctuation ({M}agesa et al., 2000). {T}he paradoxical situation of gametocytes following a circadian morning rhythm in spite of the nocturnal activity of vectors is discussed.},
