Feeding deterrence in agricultural pests such as hemiptera, lepidoptera and coleoptera

Abstract

Compounds are used as agents that deter feeding of crops by agricultural pests such as hemiptera, lepidoptera and coleoptera, including, but not limited to, stink bugs, codling moth larvae and granary weevils. Feeding deterrence is obtained by contact of the insects with at least one of the compounds of the structure (I) wherein R is —OH, ═O, —OC(O)R, —OR, or —(OR), wherein each R, is 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 OR 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, —(CH2)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.
