RESUMEN
The Guard aerosol generator is a universal multioperational device without a field-of-use restriction in the application of permitted chemical and biological substances, by combining the function of a controlled dispersion aerosol generator and a remote small- and large-drop sprayer in one mechanism and can use aerosol pesticides. The drop fractionation range is as follows: 3-50, 50-100, 100-300, and 200-400 microm for aerosol, dead water, small-drop, and large-drop spraying, respectively, with smooth and step control of working liquid drops. Treatment using the Guard generator has been shown to be highly effective against agricultural and forestry pests. This paper describes the advantages of the Guard sprayer over those of the conventional air and ground ones. The long-term use of the Guard generator to control mosquitoes and ticks in the Tyumen region could substantially improve the epidemiological situation of tick-borne infections and protect children's recreation centers from attacks of bloodsuckers.

There are synchronous undulating variations in the number of ticks and in the incidence of tick-borne encephalitis and Ixodes tick-borne borreliosis in the south of the Tyumen Region. Since 1990s, there has been an increase in the incidence of tick-borne infections and in the number of ticks. The highest epidemic risk areas of 1418 have been treated with acaricides due to the additional financing made by the Tyumen Region in 2002-2004. The treatments with the agents Sipaz-super and Briz (25% c.e. cipermethrin) have ensured 98-100% freedom of the areas from ticks. In Tyumen and in the south of the Tyumen Region, the number of human suction of ticks has reduced from 601 and 1231 per 100,000 in 2001 to 424 and 658 cases in 2004, respectively. The authors have developed guidelines for tick-controlling measures in large areas of the Tyumen Region.

Measures for protection of the general population from the attacks of vectors of natural and focal infections were implemented by OOO "Spetsbioservis" at the expense of the regional budget in the involving foci oftick-borne encephalitis (TBE) and Ixodes tick-borne encephalitis in the south of the Tyumen Region during 2002-2004. The organizational and tactical issues of ground antitick treatments were perfected during this work. The paper describes the maximum effective completeness of teams of disinfectors and their supply with materials and equipment, as applied to local conditions. This scheme of organizational and tactical measures for acaricidal treatments in the south of the Tyumen Region in 2002-2004 has indicated their high effectiveness and mobility. In 2002-2003, tick bites were not recorded in children's health facilities. In these years, the incidence of TBE in the population of Tyumen reduced by 39.3% as compared with 2001. The qualitative implementation of acaricidal treatments, their extended scopes, successively intensified sanitary educational work among the population, and introduced personal prophylactic agents (repellents and protective clothes) will substantially affect the epidemiological situation associated with tick-borne infections in the region.

Field trials of an aerosolic regulated dispersity generator used to protect the areas of children's health centers (CHC) from bloodsucking two-winged insects were performed within the framework of the Tumen Administration's program on human protection from tick-borne encephalitis in the 2003 season. The technological parameters of the generator's operation and the organizational and tactical points of aerosolic treatments were worked on during these trials. The latter demonstrated the high efficiency of the use of insecticidal aerosols for the protection of CHC areas. The elaborated scheme of measures permitted large-scale aerosolic treatments in an area of more than 12,000 m2, by protecting 15 CHCs from attacking of bloodsucking insects. The obtained positive results may be used by specialists in other regions of Siberia.
