Methods of monitoring and controlling the walnut twig beetle,
View Patent ↗Disclosed are methods which include exposing a beetle of the species Pityophthorus juglandis and/or treating surfaces susceptible to infestation by the species or to infection by Geosmithia morbida with compositions including one or more semiochemicals capable of being produced by Pityophthorus juglandis . The semiochemicals can be 3-methyl-2-buten-1-ol, conophthorin or chalcogran. Also disclosed are compositions and systems used in the methods.
1. A system comprising:
an effective amount of a composition, the composition comprising a semiochemical capable of being produced by Pityophthorus juglandis , and
a permeable container or a support substrate holding the composition and configured to release the semiochemical over a period of time at a release rate,
wherein the system is configured for use in the treatment of a surface subject to infestation by Pityophthorus juglandis , and further wherein the semiochemical is 3-methyl-2-buten-1-ol and the release rate is in the range of from about 0.2 μg/day to about 200 mg/day.
2. The system of claim 1 , wherein the system further comprises another composition comprising a racemic mixture of trans-(5S,7S)-7-methyl-1,6-dioxaspiro[4,5]decane, (−)-trans-(5S,7S)-7-methyl-1,6-dioxaspiro[4,5]decane, a racemic mixture of 2-ethyl-1,6,-dioxaspiro[4,4]nonane, or combinations thereof.
3. The system of claim 1 , comprising the permeable container.
4. The system of claim 3 , wherein the permeable container is a pouch or a bubble cap.
5. The system of claim 1 , further comprising a trap coupled to the composition, the trap configured to capture Pityophthorus juglandis.
6. The system of claim 1 , wherein the release rate is in the range of from about 0.1 mg/day to about 150 mg/day.
7. A system for treating a surface subject to infestation by Pityophthorus juglandis , the system comprising:
a composition comprising a semiochemical capable of being produced by Pityophthorus juglandis ; and
an insect trap comprising a bait;
wherein the semiochemical is 3-methyl-2-buten-1-ol and the bait for the insect trap is the composition; and further wherein the system is configured to release the semiochemical over a period of time at a release rate in the range of from about 0.2 μg/day to about 200 mg/day.
8. The system of claim 7 , further comprising a release device holding the composition and configured to release the semiochemical over the period of time at the release rate.
9. The system of claim 7 , wherein the release rate is in the range of from about 0.1 mg/day to about 150 mg/day.
