Chromosome number in Coptotermes formosanus (Isoptera: Rhinotermitidae)

摘要

Observation of cells from the ovaries and testes of primary kings and queens, and dealates, indicated that the haploid chromosome number in Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae) is 21. This is comparable to reports of chromosome numbers in Reticulitermes species. No permanent interchange complexes were observed in C. formosanus, possibly because of relatively limited inbreeding in C. formosanus colonies in comparison to termite species in which such complexes have been found.
