Abstract
Abstract An efficient cost- and labor-saving method is proposed for controlling the population of two kinds or more of different species of insectan pests in a field by means of distributing dispensers of sex pheromone compounds for the respective species of the insects when one of the sex pheromone compounds is an unsaturated C 10 to C 12 alcohol and the other is an unsaturated C 14 to C 20 acetate or aldehyde. When these two classes of the compounds are mixed in such a proportion that the overall solubility paramater δ of the mixture is 9.1 to 9.7 and the mixture is contained in a dispenser body made of polyethylene or a copolymer mainly composed of ethylene moiety, the two compounds can be concurrently emitted from the dispenser in the form of vapor each at a controlled rate over a desired length of time.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
137 words
A method for simultaneously controlling the rates of concurrent vapor release of a first sex pheromone compound of insects which is an aliphatically unsaturated alcohol having 10 to 12 carbon atoms in a molecule and a second sex pheromone compound of insects which is an aliphatically unsaturated acetate or aldehyde having 14 to 20 carbon atoms in a molecule, which comprises: (a) mixing the first and the second sex pheromone compounds of insects into a liquid mixture; and (b) enclosing the liquid mixture in a container having a wall made of a polyethylene or a copolymer of ethylene composed of at least 90% by weight of an ethylene moiety so that the first and the second sex pheromone compounds concurrently permeate the wall as a barrier and are released to the atmosphere in the form of vapor.
Claim 2
Independent Claim
137 words
A method for simultaneously controlling the rates of concurrent vapor release of a first sex pheromone compound of insects which is an aliphatically unsaturated alcohol having 10 to 12 carbon atoms in a molecule and a second sex pheromone compound of insects which is an aliphatically unsaturated acetate or aldehyde having 14 to 20 carbon atoms in a molecule, which comprises: (a) mixing the first and the second sex pheromone compounds of insects into a liquid mixture; and (b) enclosing the liquid mixture in a container having a wall made of a polyethylene or a copolymer of ethylene composed of at least 90% by weight of an ethylene moiety so that the first and the second sex pheromone compounds concurrently permeate the wall as a barrier and are released to the atmosphere in the form of vapor.
Claim 3
Independent Claim
181 words
A method for simultaneously controlling the rates of concurrent vapor release of a first sex pheromone compound of insects which is an aliphatically unsaturated alcohol having 10 to 12 carbon atoms in a molecule and a solubility parameter δ in the range from 9.9 to 10.1 and a second sex pheromone compound of insects which is an aliphatically unsaturated acetate or aldehyde having 14 to 20 carbon atoms in a molecule and a solubility parameter δ in the range from 8.6 to 9.0, which comprises: (a) mixing the first and the second sex pheromone compounds of insects into a liquid mixture in such a proportion that the mixture has an overall solubility parameter δ in the range from 9.1 to 9.7; and (b) enclosing the liquid mixture in a container having a wall made of a polyethylene or a copolymer of ethylene composed of at least 90% by weight of an ethylene moiety so that the first and the second sex pheromone compounds concurrently permeate the wall as a barrier and are released to the atmosphere in the form of vapor.
Claim 4
Independent Claim
181 words
A method for simultaneously controlling the rates of concurrent vapor release of a first sex pheromone compound of insects which is an aliphatically unsaturated alcohol having 10 to 12 carbon atoms in a molecule and a solubility parameter δ in the range from 9.9 to 10.1 and a second sex pheromone compound of insects which is an aliphatically unsaturated acetate or aldehyde having 14 to 20 carbon atoms in a molecule and a solubility parameter δ in the range from 8.6 to 9.0, which comprises: (a) mixing the first and the second sex pheromone compounds of insects into a liquid mixture in such a proportion that the mixture has an overall solubility parameter δ in the range from 9.1 to 9.7; and (b) enclosing the liquid mixture in a container having a wall made of a polyethylene or a copolymer of ethylene composed of at least 90% by weight of an ethylene moiety so that the first and the second sex pheromone compounds concurrently permeate the wall as a barrier and are released to the atmosphere in the form of vapor.
Claim 5
Independent Claim
148 words
A method for simultaneously controlling the rates of concurrent vapor release of a first sex pheromone compound of insects selected from the group consisting of E,E-8,10-dodecadienol and E-5-decenol and a second sex pheromone compound of insects selected from the group consisting of Z-8-dodecenyl acetate, 11-tetredecenyl acetate, Z,Z-3,13-octadecenyl acetate and Z,Z-11,13-hexadecadienal which comprises: (a) mixing the first and the second sex pheromone compounds of insects into a liquid mixture in such a proportion that the mixture has an overall solubility parameter δ in the range from 9.1 to 9.7; and (b) enclosing the liquid mixture in a container having a wall made of a polyethylene or a copolymer of ethylene composed of at least 90% by weight of an ethylene moiety so that the first and the second sex pheromone compounds concurrently permeate the wall as a barrier and are released to the atmosphere in the form of vapor.
