Pyrethrins is a mixture of pyrethrins, which are insecticidal compounds derived from the Chrysanthemum flower. Pyrethrins induce mortality of C. fatigans mosquitoes when used at a concentration of 200 mg/ft alone or in combination with the synergist piperonyl butoxide on glass, wood, or mud panels, with the effect persisting for 3-4 weeks. Pyrethrins are toxic to rats via oral administration (LCs = 700 and 1,030 mg/kg for female and male rats) and inhalation (LD = 3.4 mg/L), as well as to rainbow trout (LC = 52.2 µg/L). Formulations containing pyrethrins have been used in the control of insects in agriculture and horticulture.

工作液浓度 mg/ml;

DMSO母液配制方法 mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,

体内配方配制方法μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。

配置后的溶液总体积

1. 首先保证母液是澄清的;
           2. 一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
