[The species and karyotype composition of malaria mosquito larvae in different water reservoirs of the city of Moscow].

The species and karyotype composition of malaria mosquito larvae was investigated in different water reservoirs of the city of Moscow. Cytogenetic analysis identified 2 malaria mosquito species: An. maculipennis Mg and An. messeae Fall. An. messeae was predominant in all the biotopes studied. The proportion of An. maculipennis varied from 0 to 23.8% and averaged 6.27%. An. messeae larvae were found to have chromosomal polymorphism. Individual local An. messeae populations having a definite, historically established, time and space resistant karyotype structure were shown to form in Moscow. The resistance of the karyotype structure of the populations was provided by reversible fluctuations in the rate of chromosomal inversions.

[Distribution of aedes (stegomyia) aegypti l. and aedes (stegomyia) albopictus skus. mosquitoes on the Black Sea coast of the Caucasus].

There is evidence that in the Black Sea coastal area, Ae.albopictus mosquitoes are encountered everywhere from N. Afon to Dzhubga over a length of 250 km of the coast and Ae.aegypti ones are from N. Afon to Agoi, Tuapse District (215 km). The Ae.albopictus mosquitoes have extended 44 km in length and 600 m in height in the eastern part of the coast (Krasnaya Polyana).

[Detection of Aedes (Stegomyia) albopictus skus. Mosquitoes in the Russian Federation].

Aedes (Stegomyia) albopictus Skus. mosquitoes were for the first time collected in the Bolshoi Sochi region in the Russian Federetion. 16 females and 1 male were morphologically and genetically identified as Ae. albopictus and Aedes aegypti, respectively.

[Results of epidemiological surveillance of malaria vectors in the Moscow open water reservoirs].

In the past 2 years, the malaria epidemiological situation in Moscow has drastically deteriorated, sporadic cases of local transmission of tertian malaria (Plasmodium vivax) have been notified, which permits one to pose a problem, namely to eliminate malaria in the megapolis by 2010. Monitoring and assessment of the entomological situation, surveillance of the malaria vectors Anopheles mosquitoes in particular, acquire vital importance. The entomological surveillance has shown its efficiency on the territory of the megapolis and a need for continuous monitoring and assessment in future in order to consolidate the achieved success and to attain malaria elimination in Moscow by 2010. The major benefit of hydraulic measures is that they are directed on fundamental radical environmental enhancement. The impact of timely and properly implanted hydraulic measures is long-term, therefore this prophylactic line has been considered to be of priority.

[Results of epidemiological supervision of malaria vectors in the open water reservoirs of Moscow].

In the past 2 years, the malaria epidemiological situation has drastically improved in Moscow: only sporadic cases of local transmission of tertian (Plasmodium vivax) malaria have been notified, which sets a task to eradicate malaria in the megalopolis in 2010. In this connection, the surveillance of the malaria vectors Anopheles mosquitoes is assuming prime importance. The results of entomological monitoring have shown its efficiency on the territory of the megalopolis. Main efforts have been directed to the application of safe controlling methods against the mosquitoes and to hydraulic engineering actions to reduce "area susceptibility". Entomological observations have demonstrated benefits from the correctly chosen and constantly performed hydraulic engineering measures that guarantee a long-term and positive impact on the malaria situation.
