Field test of fly control using Nankor : 0, 0-dimethyl 0-2, 4, 5-trichlorophenyl phosphorothioate

Abstract

Field tests of fly control using Nankor^[○!R] (0, 0-dimethyl 0-2, 4, 5-trichlorophenyl phosphorothioate) were carried out from 21 Sept. to 21 Oct., 1960, in a rural district in Mino, Osaka Prefecture, Japan. The results were summarized as follows : By the spray of 200cc of 0.5% kerosene solution of Nankor per 33m^2 in the dwellings or 100cc of 0.5% emulsion of Nankor per a square meter in the barns of the live-stock, the fly population estimated by using fly ribbons was decreased remarkably and the effect of Nankor lasted for 7 days. On the second time (7 Oct.), the fly control was done by renewing of litter and the spraying in the barns of the live-stock. As the result, the fly population in the dwellings was gradually decreased and its effect lasted for 7 days. The application of 2 liters of 0.025% emulsion of Nankor per a square meter was effective to fly larvae in latrines, but the larvae emerged again in 11 days after the application.
