摘　　要：采用点滴法,测定野西瓜苗不同溶剂提取物、不同月份乙醇提取物、不同部位乙醇提取物对枸杞蚜虫的活性。结果表明,氯仿提取物、十月份乙醇提取物、籽的乙醇提取物的活性最高,48h的校正死亡率分别为86.39%、88.17%、91.56%。由此表明,野西瓜苗对枸杞蚜虫具有较强的触杀活性,为开发以野西瓜苗为原料的植物杀虫剂提供依据。The drop method was used to determine the insecticidal activities to Wolfberry aphids of Hibiscus trionum L extracts from different polar solvents,different months,and different parts.The results showed that Chloroform extract,October ethanol extract,Seed of ethanol extract had the highest activity.The corrected mortalities of 48h were 86.39%,88.17%,and 91.56%,respectively.It showed that Hibiscus trionum L had very high contact toxicity to wolfberry aphids.
