Measures Undertaken for Aedes aegypti and Aedes albopiсtus Control in 2016 in Sochi, Results and Ways of Improvement

Objective of the study is to assess the effectiveness of anti-mosquito measures (against Aedes aegypti and Aedes albopiсtus mosquitoes) in the territory of Sochi and determine the ways to improve the tactics of insecticide, including larvicide, treatments.
Materials and methods. The monitoring data were analyzed in 156 points of mosquito numbers counting, 57 of which were located at sites that were subjected to treatment, including repeated ones. The count of mosquitoes was carried out by the “observer” method within 20 minutes. Statistical processing of the data was carried out using the “Past” package. Differences in mean values were calculated using the Mann-Wilcoxon-Whitney test. At the points of detection of Ae. aegypti or Ae. albopictus mosquitoes additional targeted anti-mosquito treatments were carried out. Results and conclusions. In 2016, an extremely low numbers of mosquitoes Ae. aegypti were observed. Abundance of mosquitoes Ae. albopictus is described as “high”: more than 11,000 specimens were collected in the territory stretching from the state border with the Republic of Abkhazia in the east to the city of Novorossiysk, inclusive, to the west.
The highest numbers of mosquitoes Ae. albopictus were registered in the territory of cemeteries. Performed anti-mosquito activities demonstrated their effectiveness in urbanized areas and some park zones with a high numbers of permanently residing population and tourists due to higher treatment density, small number of places favorable for the breeding of mosquitoes Ae. albopictus directly in these territories and nearby. To prevent the spread of mosquitoes Ae. aegypti and Ae. albopictus in the territory of epidemically significant objects from neighboring sites, monitoring of their numbers should be continued throughout the city and in all potential habitats. The continuation of monitoring activities across the entire Black Sea coast remains a topical issue due to the possibility of further expansion of the mosquitoes areal.
