Intrapopulation differentiation of cytogenetic structure in species of the genus Chironomus (Chironomidae: Diptera)

摘要

Intrapopulation cytogenetic differentiation caused by seasonal and annual variation of the cytogenetic population structure in Chironomus plumosus, C. balatonicus, and Camptochironomus tentans was examined. Significant seasonal and annual differentiation in populations of these species was absent. The level of intrapopulation cytogenetic differentiation was estimated. Mean intrapopulation genetic distances were 0.002±0.0004 in C. plumosus, 0.003±0.0005 in C. balatonicus, and 0.009±0.0026 in C. tentans.
