Abstract: A pyrethroid,alpha-cypermethrin,manafactured in Guangzhou,was tested against the larvae of mosquito, C.quinquefastiatus,and housefly, Musca domestica,in comparison with deltamethrin in the laboratory. The LC50 was 0.001 8mg/L for alpha-cypermethrin,and comparison with 0.001 38mg/L for deltamethrin against mosquito. The LD50 was 0.003 59mg/♀ for alpha-cypermethrin,and 0.002 03mg/♀ for deltamethrin against housefly.
