title: [Comparative assessment of several methods of calculating the number of sandflies in the open air (Psychodidae)].
abstract: In summer of 1973-1974 a comparative counting of the number of sandflies was carried out by two methods in the Turkmenian Soviet Socialist Republic. Sheets of oil paper fastened vertically to two wires at a height of 60 cm above the ground at a distance of 20 cm one from another (barriers) and sheets in the form of "flags" (Dergachova and others, 1973) were used simultaneously. 15860 sandflies (X on one sheet 31.2+/-3.2 specimens) were collected on 50 barriers consisting of 10 sheets each; and on 500 flags 7640 sandflies (X on one flag 15.3+/-1.37 specimens) were collected. When sandflies are caught on flags the coefficient of counting equal to 2.1+/-0.37 should be taken.
