Polytene chromosomes arrangement of chironomus and polypedilum midge larvae

Chironornus and Polypedilum are among important genera in Chironomidae family. Both genera are abundance and very diverse in aquatic ecosystem. Chironomus and Polypedilum are dominant and frequently found during the sampling processes. The objectives of this study were to establish the standard poly...
