First evidence for breeding Aedes aegypti L in the area of Greater Sochi and in some towns of Abkhasia

A preliminary survey of some widely spaced settlements in Greater Sochi (and in the city of Sochi) in a period of late July to early October 2007 has revealed man-biting females and swarming males of Aedes aegypti females indoors and outdoors. Man-biting Ae. aegypti females, like males swarming near...

Summary:A preliminary survey of some widely spaced settlements in Greater Sochi (and in the city of Sochi) in a period of late July to early October 2007 has revealed man-biting females and swarming males of Aedes aegypti females indoors and outdoors. Man-biting Ae. aegypti females, like males swarming nearby, were also present in the town of Gudauta under study in September (the males and females of this species were found on one-day youngsters in the animal houses) and in the suburbs of the town of Sukhumi (Republic of Abkhazia). Ae. aegypti breeding places and larvae were revealed at the back of houses in Gudauta. Detection of not only males, but also females and preimagoes of this species suggests that a local breeding Ae. aegypti population is available in this area. The findings show that a local breeding population of Ae. aegypti mosquitoes has reemerged in the inspected area of the Black Sea coast (Tuapse-Sukhumi) with a humid Mediterranean climate after 35-40-year absence. Prevention of outbreaks of menacing human arbovirus diseases in the importation of their pathogens to the health resort-tourist area of the Caucasian Black-Sea coast requires urgent organization of a continuous entomological service for environmental monitoring, organization, and implementation of measures to eradicate Ae. aegypti.
