本文报道了速灭灵(右旋苯醚菊酯)对德国小蠊和家蝇的药效,实验采用玻璃瓶接触法,实验结果表明速灭灵对家蝇的半数致死浓度LC_(50)=0.714mg/m~2:其对德国小蠊的半数致死浓度LC_(50)=42.425mg/m~2。速灭灵原药是日本住友化学工业株式会社新近在国内推广的拟除虫菊酯类杀虫剂,其杀死力较强,而且其毒性极低。
In this paper, the efficacy of nifedipine (D-phenylenethrin) against German cockroach and housefly was reported. The glass bottle contact method was used in the experiment. The experimental results showed that the median lethal concentration (LC50) 0.714mg / m ~ 2: its LC50 for German cockroach (42) = 42.425mg / m ~ 2. The main drug is the pyrethroid insecticide recently promoted by Sumitomo Chemical Co., Ltd. in Japan. Its killing power is high and its toxicity is very low.
