Genetic variability and differentiation of natural populations of Chironomus plumosus L. and C. balatonicus Devaiet al. were studied. The genetic structure of 3 C. plumosus and 4 C. balatonicus populations were described using electrophoretical analysis of 21 enzyme loci. C. plumosus and C. balatonicus populations are characterized by the similar parameters of genetic variability, which indicate high level of genetic polymorphism. For C. plumosus .hivin.P0.95 is 0.557 .+-. 0.3, .hivin.Hob is 0.194 .+-. 0.018, .hivin.a is 2.15 .+-. 0.048; for C. balatonicus .hivin.P0.95 is 0.526 .+-. 0.038, .hivin.Hob is 0.177 .+-. 0.014, .hivin.a is 1.97 .+-. 0.05. Interpopulational coefficient of genetic distance is 0.029 .+-. 0.002 for C. plumosus and 0.041 .+-. 0.006 for C. balatonicus. Genetic distance between the species is 0.346 .+-. 0.009, which permits to consider C. plumosus and C. balatonicus to be sibling species. Adh, Idh-1 and Got-2 are diagnostical loci in determination of species.
