[Comparative study on polytene chromosomes of two isolates of Simulium quinquestriatus].
The salivary glands were exposed and isolated from the larvae of Simulium quinquestriatus and stained in carbol fuchsin, squashed between slide and coverslide. Slides were examined and photographed under microscope to measure the polytene chromosomes. Systematic analysis was made. Results indicated that the number of the polytene chromosomes of both isolates is three. The main characteristic chromosomal structures are homologized. Only the banding types of II L are different.
