Abstract: The results of the experiment showed that FS-1 Shachongwang had the Characteristics of quick knockdown, strong lethality, broad range for insects, iong lasting time for themosquito,the housefly,the cockroach .the flea and the mite ect.After being stored for 15 monthsunder the usual temperature .it still had good effect on insects and its decomposition rate of activecontent was 3.69 percentage.The stability of its emulsifying agent was good.It did not grate afteradding 30～50 times water to it.

摘要： 目的：研究FS－1杀虫王透明水剂的稳定性。方法：分别进行稳定性测定、乳化性状观察；用气相色谱－程序升温法，测定药物有效含量；用直接喷雾法，观察杀虫效果。结果：新配制的药剂对家蝇、淡色库蚊、德国小蠊的KT₅₀分别为3′10″、1′20″、2′50″，24小时死亡率均为100％；常温下存放15个月，仍保持较高的杀虫效力。有效含量分解率为3．69％。加水30～50倍不分层。结论：该药剂对卫生害虫击倒速度快，致死力强，杀虫谱广，持续时间长，乳化稳定性好。
