Feeding deterrence of pests such asand

Abstract

Compounds are used as agents that deter feeding by insect pests, such asand. Feeding deterrence is obtained by contact of the insect pests with at least one of the compounds of the structure (I) wherein R is —OH, ═O, —OC(O)R, —OR, or —(OR), each Ris independently an alkyl group containing from 1 to 4 carbon atoms and Ris a branched or straight chain, saturated or unsaturated, hydrocarbyl group with zero to two double bonds and from 1 to 15 carbon atoms; X is O or CHwith the proviso that when X is O, R can only be ═O; each Z is independently (CH) or (CH); y is a numeral selected from 1 and 2; Ris H or a branched or straight chain, saturated or unsaturated hydrocarbyl group with zero to two double bonds and from 1 to 15 carbon atoms; Ris H or a branched or straight chain, saturated or unsaturated hydrocarbyl group with zero to three double bonds and from 1 to 15 carbon atoms; Ris selected from H, a branched or straight chain, saturated or unsaturated hydrocarbyl group with zero to three double bonds and from 1 to 15 carbon atoms, —(CH)OH, —C(O)OR, —CHC(O)OR, —CHC(O)R, —C(O)NRR, and —CHC(O)NRRwhere each of R, R, R, R, R, Rand Ris independently selected from H and a branched or straight chain, saturated or unsaturated hydrocarbyl group with zero to three double bonds and from 1 to 15 carbon atoms and n is an integer of from 1 to 12; the bond between the 2 and 3 positions in the ring structure may be a single or a double bond; and wherein the compounds of structure (I) contain from 9 to 20 total carbon atoms in the compounds.
