The Chromosome Analysis of 5 Diptera Insect Cell Lines

The Chromosome analysis of 5 Dip tera insect cell lineswasmade by direct method, with regular Giemsastaining. Chromosomes of these cells in metaphase were counted under the microscope. The chromosome numbersand their nuclear typeswere analyzed. C6 /36 belonged to dip loid cell lines and its chromosome mode was 6. SL2belonged to hyperdip loid cell lines and its chromosome mode range was 8～12. L-2 /M delta 2-3 belonged to hyperdip loid cell lines and its chromosome mode range was 8～20. Aedes albopictus Skuse belonged to dip loid cell linesand its chromosome mode was 6. N IH-SaPe-4 belonged dip loid or hypodip loid cell lines and its chromosome modewas 10. Chromosome numbers in the 5 cell lines were not comp letely changed.
