食茱萸、肖楠、無患子甲醇抽出物對紙張抗灰衣魚及顏色之影響

本研究探討食茱萸（Zanthoxylum ailanthoide）與肖楠（Calocedrus formosana）材部及無患子（Sapindus mukorossi）果實之甲醇抽出物對灰衣魚（Ctenolepisma longicaudata）之忌避與致死性，並分析試驗紙張經甲醇抽出物處理後對白度、色差值等性質的影響。試驗結果顯示無患子果實、食茱萸及肖楠材部之甲醇抽出物對於灰衣魚皆具有忌避效果，當以10%之抽出物濃度處理48hr時之忌避率皆高達97～100%，其中以肖楠材部之甲醇抽出物的忌避效果表現最佳，甚至在處理濃度降至0.5%時，其忌避率仍在97%左右。此外，經致死試驗結果發現，肖楠材部之甲醇抽出物在濃度5%時對灰衣魚會產生致死現象，在12hr內可達到100%之致死率。對紙張性質影響以無患子果實之甲醇抽出物對白度與色差變化最小，而肖楠材部之甲醇抽出物差異最大。綜合試驗結果發現，肖楠材部甲醇抽出物在衣魚忌避之效果最好，但對紙張之色差影響最大，其次則為食茱萸材部。由試驗結果推測，肖楠材部之甲醇抽出物對灰衣魚之致死機制可能是經由呼吸入、食入或接觸而造成死亡，此部分仍須進一步探討。

This study aimed to determine the repellency and mortality on the gray silverfish (Ctenolepisma Longicaudata) by methanolic extracts from trucks of Zanthoxylum ailanthoides, Calocedrus formosana and seed of Sapindus mukorossi. We also evaluate the whiteness and color difference value of the paper which were treated by the extracts. The result showed that all of the extracts have repellency to silverfish. After test for 48hr, the rates of repellency were 97 to 100% at the concentration of 10%. Calocedrus formosana obtained the best repellency with repellency rate achieved about 97% when the concentration was 0.5%. In addition, when the concentration is 5%, the mortality of Calocedrus formosana extracts are 100% while the silverfish was treated after 12hr. Sapindus mukorossi treated papers show the minimum of whiteness and color difference changes, but the whiteness and color difference changes are remarkable for Calocedrus formosana. To summarize, Calocedrus formosana has the best efficiency on repellency, and then Zanthoxylum ailanthoides; on mortality, Calocedrus formosana has the best efficiency. Afterward more research should be carried out to make sure if the mortality of silverfish was caused by breath in or ingestion or contact with the extracts of Calocedrus formosana.
