Abstract: The title compounds were synthesized by the esterification reaction of 1,3,5-substituted-4-methylol pyrazole with substituted cyclopropane carbonyl chloride,their structure were confirmed by means of 1H NMRand elementary analysis.The bioassay showed that the lethal of 1,2 against mosquito larvae at 1.5×10-7mol/Lwere 100%,The killing activities of 1 and 2 were higher than those of pyrethroid insecticides phenothrin(2×10-6mol/L)and phthalthrin (4×10-6mol/L).The other compounds 3,5,12 showed a higher antiphytoviral activity against TMV(tobacco mosaic virus)compared with DHT(2.4-dioxohexahydro-1,3,5-triazine).
