Abstract
Abstract The insect attractants of the present invention are highly specific for yellow jackets (Vespula spp.), attracting few other insects and no beneficial species such as honey bees. These attractants are organic esters having a total of from nine to 12 carbon atoms, and they have at least one center of unsaturation, as exemplified by cis-3-hexenyl butyrate and 2-methylpentyl crotanate, or an alicyclic radical as in 4-methylcyclohexyl butyrate. The ester, 2,4-hexadienyl butyrate, was outstanding in field tests. Incorporated into compositions containing an insecticide, chemosterilant or other control agent, the attractants provide an improved means of reducing or eliminating populations of yellow jackets.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
86 words
A METHOD OF ATTRACTING YELLOW JACKET WASP (VESPULA SPP) COMPRISING EXPOSING SAID WASPS TO AN EFFECTIVE ATTRACTANT AMOUNT OF AN ESTER HAVING AN ALCOHOL MOIETY AND AN ACID MOIETY AND HAVING A CHAIN LENGTH OF FROM 10 TO 12 CARBON ATOMS, SAID ALCOHOL MOIETY BEING DERIVED FROM A SATURATED ALIPHATIC HYDROCARBON ALCOHOL CONTAINING FROM FIVE TO SIX CARBON ATOMS AND SAID ACID MOIETY BEING DERIVED FROM AN ACID SELECTED FROM THE GROUP CONTAINING OF ALKENOIC AND ALKUNOIC ACIDS EACH CONTAINING FROM FOUR TO SEVEN CARBON ATOMS.
Claim 2
Independent Claim
86 words
A METHOD OF ATTRACTING YELLOW JACKET WASP (VESPULA SPP) COMPRISING EXPOSING SAID WASPS TO AN EFFECTIVE ATTRACTANT AMOUNT OF AN ESTER HAVING AN ALCOHOL MOIETY AND AN ACID MOIETY AND HAVING A CHAIN LENGTH OF FROM 10 TO 12 CARBON ATOMS, SAID ALCOHOL MOIETY BEING DERIVED FROM A SATURATED ALIPHATIC HYDROCARBON ALCOHOL CONTAINING FROM FIVE TO SIX CARBON ATOMS AND SAID ACID MOIETY BEING DERIVED FROM AN ACID SELECTED FROM THE GROUP CONTAINING OF ALKENOIC AND ALKUNOIC ACIDS EACH CONTAINING FROM FOUR TO SEVEN CARBON ATOMS.
Claim 3
Independent Claim
12 words
The method of claim l in which the ester is 2-methylpentyl crotonate.
Claim 4
Dependent Claim
12 words
The method of claim 1 in which the ester is pentyl 2-heptynoate.
Claim 5
Dependent Claim
12 words
The method of claim 1 in which the ester is isopentyl 2-heptynoate.
Claim 6
Independent Claim
85 words
A method of attracting yellowjacket wasps (Vespula spp.) comprising exposing said wasps to an effective attractant amount of an ester having an alcohol moiety and an acid moiety and having a chain length of from 10 to 11 carbon atoms, said alcohol moiety being derived from an unsaturated aliphatic hydrocarbon alcohol containing from four to six carbon atoms and said acid moiety being derived from an acid selected from the group consisting of alkenoic and alkynoic acids each containing from four to seven carbon atoms.
Claim 7
Independent Claim
85 words
A method of attracting yellowjacket wasps (Vespula spp.) comprising exposing said wasps to an effective attractant amount of an ester having an alcohol moiety and an acid moiety and having a chain length of from 10 to 11 carbon atoms, said alcohol moiety being derived from an unsaturated aliphatic hydrocarbon alcohol containing from four to six carbon atoms and said acid moiety being derived from an acid selected from the group consisting of alkenoic and alkynoic acids each containing from four to seven carbon atoms.
Claim 8
Dependent Claim
12 words
The method of claim 5 in which the ester is 2,4-hexadienyl crotonate.
Claim 9
Dependent Claim
12 words
The method of claim 5 in which the ester is 3-butynyl 2-heptynoate.
