A cyclopropanecarboxylate represented by the formula, WHEREIN R1 is hydrogen atom, methyl or ethyl group, R2 is methyl, ethyl, 2-methyl-1-propenyl or 2-methoxycarbonyl-1propenyl group when R1 is hydrogen atom, or R2 is methyl or ethyl group when R1 is methyl or ethyl group, and R3 and R4 are respectively hydrogen atom, methyl or ethyl group, provided that the case where R1, R3 and R4 are simultaneously hydrogen atom is excluded, R5 is a lower alkynyl or a lower alkenyl group, R6 is a lower alkynyl, a lower alkenyl or a lower alkoxyalkyl group, R7 is hydrogen atom, a lower alkyl or a lower alkoxy group or a halogen atom, n is 1 or 2, and X is oxygen or sulfur atom, which is useful as an active ingredient of insecticides. |
