摘要

本研究以桃園縣、彰化縣、臺南縣、臺東縣為例，於2009年至2010年間進行臺灣珍貴老樹之病蟲害調查。四縣共有333棵老樹分屬於30種，分別為桃園縣63棵、彰化縣110棵、臺南縣99棵及臺東縣61棵，樹種以榕樹、茄冬、樟樹佔的比率最高，分別為52％及22％。病蟲害調查部分病害分為7類、蟲害分為10類、生理問題分6類，不明原因有8棵，其中病害以木材腐朽、煤煙病及褐根病所佔的比例最多；蟲害則以薊馬、白翅葉蟬及白蟻所佔的比率最高；生理問題方面則以花臺及水泥柏油鋪面障礙為主；不明原因有8棵分別位於桃園縣及臺東縣。

This paper was based on previous trees disease survey (2009-2010) in Taoyuan, Changhua, Tainan and Taitung counties. A Total of 333 historical trees (Taoyuan: 63 Changhua: 110, Tainan: 99, Taitung: 61) were classified into 30 species. Ficus microcarpa (52%) and Bischofia javanica (21%) are two major historical trees in these four counties. We identified that seven tree diseases were caused by microorganisms, ten by insect pests and six by physiological disorders. But eight historical trees in Taoyuan and Taitung counties were not determined. In disease issues, wood rots caused by wood-decay fungi, sooty mold and brown root rot occupied higher proportions. For insect pests, thrip, Typhlocyba subrufa and termites were the major problems. For physiological problems, the raised growing bed and cement surface barrier are found to be major factors.
