Abstract
在臺灣，過去多用10% DDT粉劑25kg/ha用量防治鐵甲蟲，據試驗所知5% DDT粉劑45kg/ha用量、1% γ-BHC粉劑35kg/ha、1% γ-BHC粉劑25kg/ha及0.5% γ-BHC粉劑45kg/ha等4種處理其純淨殺蟲效果與10% DDT粉劑25kg/ha用量者並無明顯差別，但該等藥劑之價格不同，故應參照當時之售價而選用適宜之藥劑及用量。
This is the first report on the experiment of several kinds of chlorinated hydrocarbon insecticides against the spiny leaf beetle adults, conducted during 1950-1953. The results are shown as follows: 1. According to the laboratory investigations, it showed that 5% DDT dust with the dosage of 45 kg per ha, 0.5% γ-BHC dust 45 kg per ha, 1% γ-BHC dust 35 kg per ha and 1% γ-BHC 25 kg per ha were not different in toxicity from 10% DDT dust with the dosage of 25 kg per ha, as shown in table 1. 2. Basing on the result of field tests, corrected mortalities were obtained by various dosages and concentrations of different chemicals.
