Claims
- 1. A method of repelling conifer-infesting bark beetles from a surface subject to attack by said beetles, comprising treating the surface with a repellent compounds selected from the group consisting of: benzaldehyde, benzyl alcohol and nonanal, in amounts sufficient to repel said beetles from said surface, or eluting said compound from inert devices or carriers applied to said surface in amounts sufficient to repel said beetles from said surface.
- 2. A method of protecting individual logs, trees and groups of coniferous tree hosts from attack by conifer-infesting bark beetles, comprising treating said logs, trees and groups of coniferous tree hosts with one or more a repellent compounds selected from the group consisting of: benzaldehyde, benzyl alcohol and nonanal, in amounts sufficient to repel said bottles.
- 3. The method of claim 1 wherein said compound or mixture is combined with a green leaf volatile selected from the group consisting of hexanal, (E)-2-hexenal, 1-hexanol, (E)-2-hexen-1-ol, (Z)-2-hexen-1-ol, and (Z)-3-hexen-1-ol, and mixtures thereof.
- 4. The method of claim 2 wherein said compound or mixture is combined with a green leaf volatile selected from the group consisting of hexanal, (E)-2-hexenal, 1-hexanol, (E)-2-hexen-1-ol, (Z)-2-hexen-1-ol, and (Z)-3-hexen-1-ol, and mixtures thereof.
- 5. The method of claim 1 wherein said compound or mixture is combined with an antiaggregation pheromone selected from the group consisting of verbenone and 3-methylcyclohex-2-ene-1-one.
- 6. The method of claim 2 wherein said compound or mixture is combined with an antiaggregation pheromone selected from the group consisting of verbenone and 3-methylcyclohex-2-ene-1-one.
- 7. The method of claim 1 wherein said compound or mixture is combined with a green leaf volatile, or mixtures thereof, and an antiaggregation pheromone selected from the group consisting of verbenone and 3-methylcyclohex-2-ene-1-one.
- 8. The method of claim 2 wherein said compound or mixture is combined with a green leaf volatile, or mixtures thereof, and an antiaggregation pheromone selected from the group consisting of verbenone and 3-methylcyclohex-2-ene-1-one.
- 9. The method of claim 1 wherein said conifer-infesting bark beetles are selected from the group consisting of Dendroctonus ponderosae, Dendroctonus rufipennis, Dendroctonus pseudotsugae, Ips pini, and Dryocoetes confusus.
- 10. The method of claim 2 wherein said conifer-infesting bark beetles are selected from the group consisting of Dendroctonus ponderosae, Dendroctonus rufipennis, Dendroctonus pseudotsugae, Ips pini, and Dryocoetes confusus.
