[Behavioral features of the imago of malaria mosquitoes (Diptera, Culicidae, Anopheles) in uzbekistan].

Abstract

Morphological, cytogenetic, and molecular genetic analyses made in the Fergana, Chirchik-Akhangaran, Mirzachul, and Zarafshan physicogeographical districts of Uzbekistan revealed the closely related species An. artemievi malaria mosquito from the An. maculipennis complex. In the human settlements and natural biotopes under their canopy of 7 physicogeographical districts of Uzbekistan, there were 6 Anopheles mosquito species (An. artemievi, An. claviger, An. hyrcanus, An.martinius, An. pulcherrimus, and An. superpictus); An. superpictus is a dominant species in the human settlements and An. artemievi in subdominant. An.pulcherrimus was dominant and An. superpictus was subdominant under natural canopy conditions. The latter is of widespread occurrence in the mountain and piedmont areas of Uzbekistan. It is encountered in all the physicogeographical districts. An. artemievi is distributed in the river valleys in the Fergana, Chirchik-Akhangaran, Mirzachul, and Zarafshan physicogeographical districts. An. pulcherrimus is common in the plain river valleys, except in the Qashqadaryo physicogeographical district. An. martinius is found in the Qashqadaryo and Nizhneamudryo physicogeographical districts. Livestock houses are the most attractive day's rests for mosquitoes; utility rooms rank next in mosquito density. Housing premises are slightly occupied by mosquitoes. The maximum size of aggressive mosquitoes is noted in July, August, and early September.
