Abstract: This paper introduced a new pyrethroid insecticide prepared by the condensation of permethrin acid chlorocyl and amine alcohol,in which its synthetic procedure has also been reported. Through the element analysis of the sample,the theoretical value agreed well with that of practice determination.The biological determination of its effect has been done with flies,mosquitoes and cockroaches. The result indicated that LC₅₀ was 0.00264ppm for the larval of Culex pipiens pallens and LD₅₀ was 0.00165-0.00182ug per insect:With the dosage of 5mg/m³,the KT₅₀ was 4.7 min for adult Culex pipiens pallens and 3.7 min for Musca domestica vicina,while both of the death rates in 24h were 100%;The forced contact tests at 54mg/m² showed that KT₅₀ was 6.2 min for Periplaneta americana and 6.0 min for Blattella germanica.
