- Abstract
Stem-Boring Pest (SBP) cause the most prevalent problem that harms the health of trees. Traditional SBP prevention uses manual survey of wormholes and is a time-consuming process. This paper proposes a novel Trunk Wormhole Detection (TWD) method based on Bio-Impedance Spectroscopy (BIS) measurements. A horizontal and a vertical trunk wormhole phantoms are prepared, and comparative BIS measurements under the situations without and with holes are performed using a precision impedance analyzers WK6500B. Remarkable differences both on impedance amplitudes and phases have been found before and after the holes formed in the phantoms. The Cole model parameter analysis finds that the Cole parameter R∞ decreases by 43.82% in the horizontal phantom, and decreases by 63.13% in the vertical phantoms, which suggests that R∞ may be an efficient indicator to detect trunk wormholes.
