Claim:
A malononitrile compound represented by the formula (I): wherein, R 1 represents a C1 to C5 (halo)alkyl, a C2 to C5 (halo)alkenyl, a C2 to C5 (halo)alkynyl or a hydrogen atom; R 2 represents a C1 to C5 (halo)alkyl, a C1 to C5 (halo)alkyloxy, a C2 to C5 (halo)alkenyl, a C2 to C5 (halo)alkynyl, hydrogen atom or a cyano; R 3 and R 4 are the same or different and are a C1 to C6 (halo)alkyl, a C2 to C6 (halo)alkenyl, a C2 to C6 (halo)alkynyl, a C3 to C6 (halo)cycloalkyl, a C4 to C6 (halo)cycloalkenyl or a hydrogen atom, or R 3 and R 4 together may form a C2 to C6 (halo)alkylene or a C4 to C6 (halo)alkenylene; R 5 represents a halogen atom, a cyano, a nitro, a C1 to C4 (halo)alkyl, a C2 to C4 (halo)alkenyl, a C2 to C4 (halo)alkynyl, a C1 to C4 (halo)alkyloxy, a C1 to C4 (halo)alkylthio, a C1 to C4 (halo)alkylsulfinyl, a C1 to C4 (halo)alkylsulfonyl, a C2 to C4 (halo)alkylcarbonyl, a C2 to C4 (halo)alkyloxycarbonyl, a C2 to C4 (halo)alkylcarbonyloxy, a phenyloxy or a phenylthio (the above-mentioned phenyloxy and phenylthio may be substituted with a halogen atom or a C1 to C3 alkyl); n is an integer of 0 to 4 and when n is 2 or more, R 5 may be the same or different.
