摘要: 目的 测定盘式蝇香的毒性和药效,验证蝇香的应用前景。方法应用霍恩氏法、玻璃方箱法和模拟现场法分别进行急性吸入毒性试验及室内药效试验。结果SD大鼠对测试蝇香的LC50>10000mg/m3,急性吸入毒性属微毒;室内药效KT50为7.77min(6.7865~8.9165),KT95为32.30min,试蝇24h死亡率为100%;模拟现场药效KT50为15.23min(14.4321~16.0910),KT95为34.66min,试蝇24h死亡率亦为100%。结论蝇香的毒性较低,药效较好,有良好的应用前景。

Abstract: Objective To evaluate the applied foreground of Zhuda brand insecticide,toxicity and efficacy was tested. Methods Using Horn's method,efficacy in laboratory and in analogous site were carried out. Results LC50 was over 10 000 mg/m3 to SD rat,this insecticide was in a low toxicity level; laboratory efficacy test to Musca domestica vicina: the KT50 and KT95 were 7.77 min(6.786-58.916 5) and 32.30 min after 24 hour,the mortality was 100%. Analogous site test to Musca domestica vicina:the KT50 and KT95 were 15.23 min (14.432-116.091 0) and 34.66 min respectively,the 24 hour mortality is 100%. Conclusion The insecticide was in a low toxicity level,efficacy was preferable.
