ABSTRACT
The authors characterize the annual cycle of An. pulcherrimus population, distinguish the stages of this cycle that differ by the population composition and number and by the size of its area. The spatial structure of the population depends on the site of water bodies for wintering and the conditions at different territories. High numbers of mosquitoes were found in the southern part of the oasis at villages of rice-growing farmers. Mosquito population densities in the central parts of the oasis are much lower and are increased nearby sandy islets.

Data on fauna of bloodsucking mosquitos (Culicidae), obtained during the survey in the irrigated part of Takhta-Kupyr District of Kara-Kalpakia in 1988-1989, are presented. The density of mosquito populations of mass species in different parts of the oasis is, to a great extent, caused by the presence of reservoirs of different types and also by the features of anthropogenic landscapes.

Physical and mechanical parameters of the paint-sprayer 2600H were studied under laboratory conditions. Studies of the feasibility of using this device for desinsection were performed under real conditions in moderate--and hot-climate areas. High efficiency of POC and pyrethroids spraying for home mosquito and fly control was demonstrated. High pressure paint-sprayer treatment ensured a longer residual effect than "Automax". The use of the sprayer for desinsection may save time and labour.
