N-phenyl-5-substituted aminopyrazole preparations and application thereof for controlling coleoptera pests. The title compound is as shown by formula (I), wherein X represents SO or S; R represents C1-C4 alkyl or C1-C4 halogenated alkyl; R1 and R2 are the same or different, and represent H, C3-C6 halogenated alkenyl, C3-C6 alkynyl, C3-C6 halogenated alkynyl, cyclopropylmethyl; with the proviso that R1 and R2 do not represent H at the same time, and when X is S and R is CF3, R1 and R2 do not represent propargyl at the same time. The insecticidal compounds have insecticidal rate of 65-100% on flea beetle at the concentration of 10-1,000 ppm. The insecticidal compounds can be prepared into wettable powder, emulsifiable concentrate, suspension, microemulsion, water emulsion and water-dispersible granule in the presence of corresponding adjuvants.
