摘要

本研究係探討以DIN EN118白蟻試驗法評估食茱萸（Zanthoxylum ailanthoides）幹材及無患子（Sapindus mukorossi）果皮之甲醇抽出物對台灣家白蟻（Coptotermes formosanus）之防治效能。試驗結果顯示，無患子果皮甲醇抽出物於1%濃度下之浸漬木塊試驗30天後重量損失率為10.6%；而食茱萸幹材甲醇抽出物浸漬木塊之重量損失率為14.6%，試驗對照組之重量損失率為40.8%。浸漬組之白蟻啃食率遠低於對照組，顯示具有良好之抗白蟻效果。

In this experiment, DIN EN118 standard method was used to evaluate the resistance of formosa termites (Coptotermes formosanus) by methanol extreacts from ＂Zanthoxylum ailanthoides＂ wood and ＂Sapindus mukorossi＂ fruits peel. After 30 days of observation, the results showed that the weight loss rates of wood blocks impregnated at 1% concentration methanol extract of ＂S. mukorossi＂ peel was 10.6%; and was 14.3% when impregnated in the extract of ＂Z. ailanthoides＂ wood, then for the control sample was 40.8%. The weight loss rate of treated wood blocks were both lower than that of control showing good effect to against the formosa termites.
