The polytene chromosomes of the mosquito Anopheles bellator compared with those of Anopheles cruzii

A photographic map was made of polytene chromosomes of ovarian nurse cells of Anopheles bellator females. The chromosomes of this species have complete or partial homology with those of A. cruzii, mainly in the telomeric and centromeric regions. Variability at the single band level was observed as asymmetric bands at seven different positions. One inversion (3Ra) was detected in the 3R arm.
