摘要

測試橡木、柳桉、楓木、鐵杉、杉木、柳杉對美洲室塵璊的抑制力，飼料中混有杉木及柳杉木屑時，塵璊族群負成長；混有橡木木屑時，繁殖大於對照組。六種木材的正己烷萃取物中，杉木稀釋500倍處理組分別殺死了72％的美洲室塵璊；正己烷萃取後再以丙酮萃取所得物的殺璊力低；杉木及柳杉的精油稀釋500倍後，均可殺死約半數的塵璊。忌避性測試中，美洲室塵璊多顯著有往萃取物反方向移動的現象，但無法以統計分析證實有忌避行為。橡木的正己烷萃取物稀釋500倍處理組為唯一表現有誘引現象者依據本研究結果，吾等推薦杉木及柳杉為居家地板或牆壁飾材，並建議勿用橡木。

The suppression by oak, lauan, maple, hemlock, China fir and Japanese fir on Dermatophagoides farinae (Hughes) was tested. Adding the powder of China fir or Japanese fir to the diet resulted in negative population growth for this dust mite. Addition of the powder of oak resulted in a higher population increase. N-hexane extracts of China fir killed 72% of mites at a concentration of 0.2%. Acetone extracts drawn after hexane extraction gave low mite mortality. Essential oils of China fir and Japanese fir killed approximately 1/2 of the tested mites. This mite showed a movement away from the extract in most of repelling tests. However, this was not proven statistically. The 0.2% hexane extract of oak was the only one showing an attractant effect. Based on the results of this study, we recommend China fir and Japanese fir for the construction of house floors and walls, but nor oak.
