    Abstract

    Chromosome studies on samples of the Anopheles gambiae complex were carried out in a village of the rice-growing area of the Rusizi Valley (Burundi). A large predominance of An. arabiensis was observed throughout the year. Anopheles gambiae was also present but represented about 4% only of the indoor resting An. gambiae s.l. The finding of human blood-fed specimens in animal shelters suggests partial exophily. Abdominal appearance observations indicated a gonotrophic dissociation during the dry season. Both An. arabiensis and An. gambiae showed a low degree of inversion polymorphism, in agreement with the general picture shown in East Africa. The most frequent karyotypes are typical of wet savannas
