    Abstract: A cyclopropanecarboxylate of the formula:

    WHEREIN R1 is methyl, R2 is lower alkoxymethyl, lower alkenoxymethyl, lower alkynoxymethyl or acyl such as lower alkanoyl, lower alkenylcarbonyl or lower alkynylcarbonyl or, when taken together with the adjacent carbon atom, R1 and R2 may represent a cyclic ketone group preferably having 4 to 6 carbon atoms and R3 is a group of the formula:

    (WHEREIN R4 is lower alkyl, lower alkenyl, lower alkynyl, benzyl, thenyl, furylmethyl, phenoxy or phenylthio, R5 is hydrogen or lower alkyl or R4 and R5 may link together to form a polymethylene chain preferably having 3 to 4 carbon atoms and X is oxygen, sulfur or vinylene) or a group of the formula:

    (WHEREIN R6 is benzyl, thenyl or furylmethyl), which is useful as an insecticide characteristic in exerting rapidly the insecticidal activity against various harmful insects.
