Morphology of the wings and attachment apparatus in the evolution of the family Hippoboscidae (Diptera).

Using a complex analysis of the molecular genetics, morphological, and ecological characteristics of Hippoboscidae flies, the phylogenetic structure and trends in the evolution of morphological characters that contribute to the ectoparasitic lifestyle of hippoboscid flies of the north of Eurasia were studied for the first time. The research was carried out on 26 Palearctic species from 10 genera. The analysis of molecular phylogeny revealed the levels of clustering of the family with the species predominantly parasitizing mammals or birds, the time of cluster formation, and the divergence of species in the Palearctic conditions.

The role of plants in the formation of species-specific features in grass flies (Diptera, Chloropidae, Meromyza).

In the current manuscript, we present the results of comparative analysis of seven species of flies in the "" cluster and of the evolutionary close species , based the following criteria: 1) 14 external key features; 2) shape and area of the anterior processes of postgonites; 3) mtDNA CO1 region and 4) host plant diversity data. We could demonstrate the primary role of host plants in species formation inside genus and calculated the timing of the divergence of and the species of "" cluster. Based on our estimates of evolution rate for mtDNA CO1 gene, we could conclude that that divergence of herbs happened before the speciation of grass flies .

Variability of the key features and revision of a group of closely related species of grassflies (Diptera, Chloropidae, ).

The following external morphological features of members of the genus Mg. have been analyzed: the ratio of the height of frontal triangle to the length of the head; the presence of black setae on the lower surface of genae; the degree of manifestation of ocellus spot; the ratio of the length of mesonotum to scutellum; the length and color of the mid strip of the mesonotum and its degree of manifestation on the scutellum; and the thickness of hind femurs. Additionally, the size and shape of anterior and posterior processes of the postgonite, and the type of attachment of the posterior process have been investigated.

[Factors Affecting the Dynamics of Circadian Activity of Frit Flies Meromyza saltatrix (L) (Diptera: Chloropidae)].

The dynamics of circadian activity in adult frit flies of the Holarctic species Meromyza saltatrix (L) from Mongolian, Moscow, and Polish populations was studied. Synchronous peaks of activity were revealed with the periodicity multiple of three-four hours, which may depend on the level of light. The direct effect of temperature and humidity on the activity of flies outside the optimal values of these factors was found.

[Phylogenetic relations between frit fly groups from the genus Meromyza based on genetic and morphological analysis].

Phylogenetic relations between groups of frit fly species from the genus Meromyza were studied on the mtDNA COI locus and on the morphology of the male reproductive apparatus. Branching of the phylogenetic tree constructed by the Neighbor-Joining method unites sequences of samples from species of the genus Meromyza in five clusters with high support. It was demonstrated that joining of species in a certain cluster corresponds to uniformity of morphological traits of male parameres.
