| 1 | In territory of Western Siberia last decade the change populations and spases structure malaria mosquitoes of a sort Anopheles is registered. It is supposed, that the change of a parity of competing kinds in common maintained reservoirs in many respects is connected to microevolutionary processes occurring at mosquitoes in conditions warming of a climate. In populations of insects as a whole there was a sharp reduction of a share of “northern” inversions XL1, XL2, 2R1, 3R1, 3L1 and distribution of variants, alternative to them | 1186 | ||||
| 2 | Researches of the chromosomal organisation and polymorphism of inversion of Far East malarial mosquito A. sinensis Wiedemann a complex «hyrcanus» were carried out in Primorye Territory. During work the chromosomal map of a kind is made, marker disks are noted. Wide intraspecific chromosomal polymorphism on all parts of autosome is revealed. The analysis of polymorphism of inversion in different points of catching of larvae in the south of Primorye Territory has revealed various level of a variety of the chromosomal variants, correlating with degree of remoteness biotopes from sea coast. The greatest polymorphism is established in population in a distance from the sea (settlement Sibirtsevo); the least is in vicinities of Vladivostok; variability has intermediate character in population of mosquitoes of state Artem.

| 3 | Experimental researches of stability to asphyxia at preimaginal stages of malarial mosquito Anopheles atroparvus are presented. In experiments of larvae and pupae of mosquitoes were in vessels with water without access to atmospheric air. The stability depends on concentration of the dissolved oxygen in water in different temperature conditions. At alternative concentration of oxygen in water two opposite tendencies of speed of destruction of preimaginal stages of development are fixed. At concentration of oxygen of 0 mg/l in three set modes of temperatures (15 °С; 23 °С; 30 °С) stability of individuals to an asphyxia from I age to pupae is increased. In the water sated with oxygen at initial concentration of oxygen of 7–8 mg/l, on the contrary – larvae of younger age differed the raised viability in comparison with individuals of advanced ages.

| 4 | Behavioral features of malarial mosquitos’ larvae Anopheles atroparvus (Diptera, Culicidae) are studied and connected with additional ways of meal reception – a substratum scraping and cannibalism. Results of experiments demonstrate that larvae of young and advanced stages Anopheles have various trophic and spatial niches in biotopes. Fall of food concurrence among stages and pressure of cannibalism on larvae of younger stages are reached. At the same time, individuals of advanced stages A. аtroparvus actively dive on depth of ten centimeters in search of forage, being switched over to alternative type of a food – the scraping.

| 5 | The article deals with the species composition and structure of the population inversion of malarial mosquitoes in Central Europe: Germany, Poland, Belarus. In the studied samples there were revealed two species Anopheles: A. messeae and A. maculipennis. There was set inversion polymorphism and XL-3R-shoulders polytene chromosomes of A. messeae. The authors discuss regularities of the composition and the frequency of the inversion of options depending on the region of Europe and the characteristics of local environmental factors habitats.

| 6 | The dynamics of the population-species of Anopheles mosquitoes in Central Siberia on trans-sect Tomsk – Achinsk – Lower Ingash – Taishet – Toulon – Bratsk. In all areas, the study found two types of malarial mosquito Anopheles messeae and A. beklemishevi. Is dominant everywhere A. messeae. Scope of A. beklemishevi first documented in the basin. Angara, 500 km to the east than observed to date. By latitudinal trans-sect from west to east in the populations of A. messeae identified two alternative trends: the decline in the diversity of options on the sex chromosome and increase the frequency diversity on both shoulders third autosomes.
