Abstract:
A method of repelling noxious insects comprising the step of exposing said noxious insects to a composition containing from 0.1 to 90 wt. %, based on the total weight of the composition, of at least one of 2-(1-hydroxyalkyl)-cycloalkanols represented by at least one of the following formulae (1), (5) and (6): wherein n is an integer of 4-10, R1 is hydrogen or a straight-chain saturated hydrocarbon radical having 1-6 carbon atoms; R2 is hydrogen or a methyl group; Rm represents m of the same or different, straight-chain or branched, saturated or unsaturated, hydrocarbon radicals R which, as a substituent group, is bonded to carbocyclic atoms; m is an integer of 0-8, provided that m is at least one when either one of R1 or R2 is an alkyl group and m is at least 2 when both R1 and R2 are alkyl groups; the sum of the carbon atoms of Rm does not exceed 8, wherein when n is 4, R is optionally an isopropylidene group which intramolecularly bridges between the third and sixth carbocyclic atoms and with the proviso that compounds of the following formulae (2)-(4) and (7)-(10) are excluded therefrom: wherein R3 and R4 are each a straight-chain or branched, saturated or unsaturated, hydrocarbon radical having 1-8 carbon atoms; and R5 and R6 are each independently hydrogen or a lower alkyl group having at most 3 carbon atoms, with the sum of the carbon atoms of R5 and R6 being 0-3.
