The biting indoor cycle of Anopheles gambiae s.s. was studied in a rural zo
ne near Bouake from 6pm to 6am. The cycle was characterized by a peak betwe
en midnight and 1am (n = 19 181). The parturity rate of biting females regu
larly increased from 6pm until 3am, then remained at a high level up to 6am
(n = 14 239). Infected bites were observed from 7pm to 6am with a maximum
between 0 and 3am, and 96.7% of them were obtained between 11pm and 4am (n
= 219). It appears that malaria transmission occurs essentially at the mome
nt when villagers are in bed. The correct use of impregnated bed nets may t
hus greatly reduce malaria transmission.
