FEEDING DETERRENCE OF PESTS SUCH AS HEMIPTERA, LEPIDOPTERA AND COLEOPTERA

摘要

Compounds are used as agents that deter feeding by insect pests, such as Hemiptera, Lepidoptera and Coleoptera. 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)R₄, —OR₆, or —(OR₆)₂, each R₆ is independently an alkyl group containing from 1 to 4 carbon atoms and R₄ is 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 CH₂ with the proviso that when X is O, R can only be ═O; each Z is independently (CH) or (CH₂); y is a numeral selected from 1 and 2; R₁ is 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; R₂ is 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; R₃ is 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)_nOH, —C(O)OR₅, —CH₂C(O)OR₇, —CH₂C(O)R₈, —C(O)NR₉R₁₀, and —CH₂C(O)NR₁₁R₁₂ where each of R₅, R₇, R₈, R₉, R₁₀, R₁₁ and R₁₂ is 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.
