Bushland et al.,-´ first found in 1944 that 10% DDT killed 100% of the body louse and duration of residual effectiveness of 10% DDT powder was between 30 days and 40 days.
Hurlbut et al. found that the korean body louse had developed a marked degree of resistance to DDT.
The problem of controlling medical insect still constitutes one of the serious problem yet to be sobed. Furthemore, the marked development of medical insect resistance to insecticide as reported here and elsewhere has added another difficulty to the control of disease.
In order to tests on residual effectiveness of insecticide, the author carried out a test on residual effectiveness of several insecticide of korean body louse. Body louse collect at old people´s home in the Taegu.
The insecticid, 5% Oil DDT, 1% Lindane powder, 5% Malathion, 1% Dibrom, 0.03% Pipedrin+O.2 % DDVP used.
Adult Iouse placed on filter paper 12 hour after treated with various insecticid and so on 48 hour, 7 day, 14 day respectively. KT,, was computed with Bliss probit analysis method. The number of knockdown louse were counted at 10 minute interval from this experiment, one can draw the following conclusions.
1. A marked difference in the residual effectiveness of insecticide was seen to exist between various insecticide.
2. The killed effect of insecticide was seen to highest effect by 0.03% Pip-Arin+0.2% DDVP.
