地下活動之家白蟻（Coptotermes formosanus）（等翅目：鼻白蟻科）之食物偏好性

"The food preference of the Formosan subterranean termite, Coptotermes formosanus (Isoptera : Rhinotermitidae)"

白蟻之食物偏好性因木材種類而異，主要係某些木材具天然抗蟻成份，令白 蟻忌避甚至具殺蟻功效。天然抗蟻成份之形成是在邊材（sapwood）老化過程中，其衍生物屯積於輸導組織中成為心材（heartwood）時所形成的。張及王整理有關熱帶木材中抗蟻成份之各國文獻，歸納4屬的熱帶樹種中，共含4類10種的抗蟻成份；如台灣紅檜（Chamaecyparis formosensis）含chamaecynone及 iso-chamaecynone兩種半酶類的重要抗蟻成份，避免受白蟻侵襲。

"Five different kinds of wood blocks, Chamaecyparis formosensis, Tectona grandis, Cunninghamia lanceolata, Gonystylus bancanus, and Pinus luchuensis, were put into one tubular can in a random complete block design, and then burried at 15 cm depth under soil for attracting the Formosan subterranean termites, Coptotermes formosanus. The loss weights were calculated after 8 weeks. The result indicated that the termite most preferred Pinus luchuensi amoung the wood blocks tested. In addition, the relative position of wood blocks in a tubular can did not affect the feeding preference of the termite."
