三蔬安生物测定的标准化研究

Study on Standardization of Bioassay for Sanshu′an

利用甜菜夜蛾 2龄幼虫对三蔬安进行不同方法的生物测定 ,研究生物测定中喂毒方法 ,观察时间以及计算方法的反应中值的稳定性。结果表明 :三蔬安产品质量检测标准在以甜菜夜蛾 2龄幼虫的生物测定中以LC50 方法操作较稳定 ,观察时间以 96h为宜 ,数理统计方法选用工作机率值法为好。

Bioassays of Sanshu′an acting on the second instar larva of spodoptera exigua are made by various means to research the feeding pesticide, observative time and the stability of reaction mid value in calculation method. The results indicate that bioassay method LC 50 is the most stable operative one for checking the quality of Sanshu′an, the optimum observation time is 96 hours, and the method of practical probability is the best mathematical statistics one.
