Species diversity and abundance of frit flies from the genus Meromyza have been assessed in coastal biotopes, grasslands, and agro-ecosystems of Vologda oblast (Russia) and Warsaw province (Poland). The Jaccard quotient of similarity (IG) of frit fly abundance has shown a uniformity between coastal banks and grasslands along these banks, as well as between(More)
The morphological diversity of antennal sensory organs in larvae of Galeruca sp. (Coleoptera, Chrysomelidae), Limnephilus centralis (Trichoptera, Limnephilidae), and Eristalis tenax (Diptera, Syrphidae) was studied. A sensory cone on the antenna was found in all the species studied. The cuticular part of the antennal cone is pierced with pores. No(More)
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(More)
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(More)
Evolutionary trends of the morphometric characteristics of postgonites (structures important for copulation) and variability of the mtDNA COI gene region were analyzed for 27 species of the genus Meromyza Mg. The total area, the area and height of the protuberance, and the length ratio of the main part and the protuberance were analyzed for the anterior(More)
We have studied distribution of mass species of flies Meromyza acuminata and M. nigrofasciata on the cereal fields of Mongolia. By the beginning of July, coming from the areas near the industrial wheat fields, M. acuminata had dominated on those fields. M. nigrofasciata was found on wild cereals. The highest number of M. acuminata was on the wheat, less on(More)
