Synthetic Aggregation Pheromone For Manipulating The Behaviour Of Codling Moth, Cydia Pomonella, Larvae
This invention relates to a composition and procedure for manipulating the behaviour of codling moth larvae, Cydia pomonella (L.) (Lepidoptera: Olethreutidae). In particular, this invention relates to the use of specific pheromone components for manipulating the behaviour of C. pomonella larvae. A composition of chemicals for manipulating the behaviour of Cydia pomonella larvae, said composition comprising two or more chemicals in all possible combinations and ratios selected from the group consisting of: 1) heptanal; 2) 6-methyl-5-hepten-2-one (sulcatone); 3) myrcene; 4) octanal; 5) 3-carene; 6) (+)-limonene; 7) (E)-2-octenal; 8) nonanal; 9) (E)-2-nonenal; 10) decanal; 11) geranylacetone.
1 . A composition of chemicals for manipulating the behaviour of Cydia pomonella larvae, said composition comprising two or more chemicals in all possible combinations and ratios selected from the group consisting of: 1) heptanal; 2) 6-methyl-5-hepten-2-one (sulcatone); 3) myrcene; 4) octanal; 5) 3-carene; 6) (+)-limonene; 7) (E)-2-octenal; 8) nonanal; 9) (E)-2-nonenal; 10) decanal; 11) geranylacetone.
2 . A composition as claimed in claim 1 wherein the composition is combined with non-pheromonal attractants of larvae.
3 . A composition as claimed in claim 1 wherein the composition is contained in, or released from, slow release devices.
4 . A composition as claimed in claim 1 wherein the composition is contained in, and released from, an apparatus or matrix that provides suitable pupation sites for attracted Cydia pomonella larvae.
5 . A method for attracting Cydia pomonella larvae into an apparatus, said apparatus containing a composition comprising two or more chemicals in all possible combinations and ratios selected from the group consisting of: 1) heptanal; 2) sulcatone; 3) myrcene; 4) octanal; 5) 3-carene; 6) (+)-limonene; 7) (E)-2-octenal; 8) nonanal; 9) (E)-2-nonenal; 10) decanal; 11) geranylacetone.
6 . A method as claimed in claim 5 wherein the apparatus is corrugated cardboard.
7 . A method as claimed in claim 5 wherein the apparatus is a matrix that polymerizes and hardens after application.
8 . A method as claimed in claim 5 wherein the apparatus or matrix contains an insect-killing agent.
9 . A method as claimed in claim 8 wherein the killing agent is a chemical insecticide.
10 . A method as claimed in claim 8 wherein the killing agent is a biological insecticide.
11 . A bait and apparatus or matrix for deployment in an area containing fruit or nut crops, said bait incorporating a composition of chemicals as claimed in claim 1 , and said apparatus or matrix providing suitable pupation sites for Cydia pomonella larvae.
12 . An apparatus or matrix as claimed in claim 11 wherein the apparatus or matrix is deployed directly to apple, pear, walnut, or other fruit or nut trees.
13 . An apparatus or matrix as claimed in claim 11 wherein the apparatus is deployed directly to apple, pear, walnut, or other fruit or nut storage bins.
14 . A method of manipulating the behaviour of Cydia pomonella larvae through attraction or arrestment which comprises exposing larvae to two or more chemicals as claimed in claim 1 .
15 . A method of diagnosing whether protection of apple, pear, walnut, or other fruit or nut crops is warranted, comprising exposing the fruit or nut crop to a composition as claimed in claim 1 , and determining whether Cydia pomonella larvae are attracted by the composition.
16 . A method of protecting apple, pear, walnut, or other fruit or nut crops from attack by Cydia pomonella larvae by deploying proximate to fruit or nut crops a composition as claimed in claim 1 .
17 . A composition as claimed in claim 1 wherein the composition is used in combination with tactics aimed at controlling adult male and/or female Cydia pomonella.
18 . A composition as claimed in claim 1 wherein the two or more chemicals are combined with a carrier.
