[Comparative karyological study of 2 close species of blackflies of the genus Eusimulium].

The structure of polytene chromosomes in the salivary gland of two hard for distinguishing species Eusimulium montium Rubz. and E. gviletense alizadei Djaf. was studied. The comparative-karyologic analysis of the taxons showed many common features in their karyotypes: complete conjugation of the homologous chromosomes in the connection between the length and the arms of chromosomes. At the same time these species are well distinguished karyologically according to the two inversions of the homozigotic type in the chromosomes I and III, to the duplication in IIL, and to the deficiency of the telometric region in IIIL of E. montium. These readjustments are considered to be secondary which suggests E. gviletense alizadei to be phylogenetically older than E. montium.

[Towards a diagnostic view of Hyalomma (Hyalomma) aegyptium (Acari, Ixodidae)].

The diagnostic characters of larval, nymphal and adult Hyalomma aegyptium (L., 1758) based on specimens from the territory of most part of the area are given. In the diagnoses of immature stages, was used the characters, which were formerly tested by the author for diagnostics of other Hyalomma species occurring in the former USSR. Commonly used characters and those which were revealed by the author as useful for the majority of Euhyalomma Filippova, 1984 and Hyalommina Schulze, 1919 species, have been used in the diagnoses of male and female. Differential diagnosis of Hyalomma aegyptium. Female: genital orifice as wide arch with straight posterior margin (fig. 2, 5); vestibular part of vagina funnel-like, greatly swollen (fig. 2, 5); setae of alloscutum stick-like, tapering in apical one (figs 2, 3, 4); second segment of palps with proximal narrowing (figs 3, 1, 2); spurs of coxae I widely separated, triangular, wide, subequal in size (fig. 3, 5). Male: any grooves of conscutum absent, except short and pit-like cervical ones (fig. 4); punctation sparce and impressive (fig. 4); adenal shields short and wide, without inner branch, posterior part widened, anteromedian margin straight (fig. 5, 4); spurs of coxae I widely separated, triangular, wide, subequal in size (fig. 6, 5). Nymph: posteromedian setae of alloscutum stick-like and, as a rule, with indented apices (fig. 7, 2); spurs of coxae I large, median spur as equilateral triangle and shorter than lateral one (fig. 7, 8); spurs of coxae II-IV well developed, with acute apices (fig. 7, 8). Larva: posterior part of scutum (behind the eyes) heavy elongated, its apex straight, postero-lateral incisions weakly developed (fig. 8, 1); spurs of coxae I as equilateral triangle in shape and with rounded apices, spurs of coxae II-III very large (fig. 8, 5).

[An analysis of the morphometric traits of the pupae of 3 populations of Testisimulium kondici (Diptera: Simuliidae)].

In the pupae of three populations of Testisimulium kondici (Bar.) the variations of nine quantitative characters are determined. The discrepancies between these populations are analyzed. With the help of statistical indices the specific distinctions of one of the studied populations from two others, which are not essentially different, is established. Earlier (Kachvorian, 1989; Kachvorian and Tonoian, 1990) karyological and phenotypical differences between the larvae of these populations were found. Considering that the isolated population develops under anthropogenic influence a link between the above discrepancies and this influence is assumed to exist.
