C and ASG banding ofCeratitis capitata(Wied.) (Diptera Tephritidae) were carried out. Results obtained by ASG banding differ according to the length of slides treatment times. With longer times we obtained C bands, with shorter times we obtained G like bands. The C bands are similar to those obtained by C-banding method. These bands agree with the bands described by others authors for C-banding. This fact shows that the same classes of heterochromatin are involved in C-banding and in ASG banding with longer times. With shorter times of treatment we obtained G-like bands. Sometime the G-like bands present variations for the chromosomes N° 1 and N° 4.
