DETAILED DESCRIPTION OF THE INVENTION

[0022] The invention's main structural component is a Dual Threaded Screw Post 9. One end of this post is tapered and can be either threaded like a wood screw or smooth like a nail. This end is mounted through the bark of a tree and into its wood. Located on the other end of this post is a Mounting Plate 11. This plate can be either mated to the post using Nuts and Washers 10 or the plate can be manufactured as part of the post.

[0023] The purpose of the Mounting Plate 11 is to mount the Controller 13 and Vibration Transducer 2 & 12. The Controller includes Signal Generator 1, Microphone 4 and Signal Analyzer 5. The Wires and Connector 14, provide electrical connectivity between the Controller 13 and Vibration Transducer 2 & 12.

[0024] A Solar Panel 6, Battery 7 and/or Power Outlet 8 provide power to the Signal Generator 1 and Signal Analyzer 5 via Wires and Connector 14. The Signal Generator 1 creates an electrical waveform and sends this waveform to the Vibration Transducer 2 & 12. The electrical shape of the waveform is representative of the vibration to be generated by the Vibration Transducer 2 & 12. This can range in frequency from 0.1 Hz to 20 Hz with preferred frequencies ranging from 1 Hz to 5 Hz.

[0025] The Vibration Transducer 2 & 12 converts the electrical waveform into mechanical vibrations that are transferred into the Tree 3 via the Mounting Plate 11 and Dual Threaded Screw Post 9. The mechanical vibrations propagate throughout the Tree 3 in a ringing decay mannerism.

[0026] The vibrations are similar to the vibrations generated when a woodpecker is pecking on the Tree 3 while foraging for wood-boring insects. The insects detect this vibration and slow or stop their movement so they will not be detected by the ‘would be’ predator. The duration of the vibrations disrupts the insect's movement and activity, including its eating habits. This prolonged disruption alters their natural development cycle and results in a deformed insect, which reduces its ability to damage the Tree 3, or it dies of starvation, which stops further damage to the Tree 3.

[0027] Different species of insects can have different predators. Therefore, the Signal Generator 1 can produce waveforms with varying amplitude, frequency, shape, duty cycle and duration to more closely match that of the selected predator.

[0028] The Microphone 4 and Signal Analyzer 5 are used together to monitor the movement and activity of the insects in the tree. The same Dual Threaded Screw Post 9 that is used to mount the invention to the Tree 3 and transfer the vibrations into the Tree 3 is also used to transfer the movement and activity vibrations generated by the insects in the Tree 3 to a Microphone 4 on the Mounting Bracket 11. This monitoring can provide the system with information to know when the insects have slowed and/or died. The Signal Analyzer 5 can halt the Signal Generator 1 when the elimination is complete. It can provide input to the Signal Generator 1 to modifywaveform. It may also provide a status output, such as LED lights.
