[Mass tracing of Aedes vexans vexans by means of radioactive phosphorus for the study of their flight range from the breeding sites].

In the valley of the Upper Yenisei IV instar larvae of A. vexans vexans were traced with 32P and then 1.86 mln imagos were released. Among 442 857 mosquitoes caught after hatching 243 were traced. Most of the traced individuals did not yet start looking for prey and were caught during the first five days near the hatching site. 14 radioactive females were caught within 4.5 km distance from the hatching site in the following weeks.

[Survival of helminth eggs in the wastewater mud in the sludge beds of Chita waterworks].

The species composition, size, and survival of human and domestic animal helminth eggs was determined in the wastewater mud in the sludge beds of the waterworks of Chita. It was shown that when the wastewater mud was little dried in the sludge beds under distinctly continental climatic conditions for three years, their complete disinvasion did not take place. The eggs of seat-worms (Enterobius vermicularis), whipworms (Trichuris trichiura), broad tapeworms (Diphylobotrium latum), and teniae were undetectable in the mud samples after the second and third year of drying. Surviving Ascaris eggs may develop in the soil to the invasion stage under the climatic conditions of Chita, by creating a risk for new infections.

[New mosquito species, Aedes (Ochlerotatus) sergievi sp. n].

The description of female, male genitalia and the fourth instar larva of a new species of mosquito, A. (O.) sergievi, from the Tuva ASSR (South Siberia) is given as well as data on its breeding places. It belongs to spring and early summer species and breeds both in fresh and salt waters. Anal gills in the larvae breeding in fresh waters are significantly (P greater than 0.001) longer than those from salt waters (mean ratio between the upper anal gill length and saddle length is 2/3 and 1/2, respectively). A. sergievi is apparently related to East Asia steppe zone (Mongolian - Chinese formations) : besides Tuva, it is found in East Kazakhstan and may occur in Zabaikalye, Mongolia and North China.
